PHP - How Secure Is My Anti-directory Transversal Code?
Hi guys, I wrote this speck of code to prevent directory transversal. However, I'm not that great with security issues, so I would like some of the gurus to offer pointers/tips/hints as to whether my code is safe or not and how to improve it.
$pageID = $_GET["pageid"]; $pageNewIDLower = strtolower($pageID); $pageNewID = ereg_replace("[^A-Za-z0-9]","",$pageNewIDLower); if (strstr($pageNewID,"../") || strstr($pageNewID,"%") != true) { // do stuff } else { include("pages/home.htm"); } If this looks wrong, let me know. I didn't take it directly from my php code as I'm on a cell phone at the moment. Similar TutorialsCan anyone help me make this more secure? I want to link the info to .inc instead of pulling this info straite from the page // cPanel info $cpuser = 'userhere'; // cPanel username $cppass = 'passwordhere'; // cPanel password $cpdomain = 'mysite.com'; // cPanel domain or IP $cpskin = 'x'; // cPanel skin. Mostly x or x2. // See following URL to know how to determine your cPanel skin // http://www.zubrag.com/articles/determine-cpanel-skin.php // Default email info for new email accounts // These will only be used if not passed via URL $epass = 'hispassword'; // email password $edomain = 'mysite.com'; // email domain (usually same as cPanel domain above) $equota = 20; // amount of space in megabytes The only time it pulls the info is in this line // Create email account $f = fopen ("http://$cpuser:$cppass@$cpdomain:2082/frontend/$cpskin/mail/doaddpop.html?email=$euser&domain=$edomain&password=$epass"a=$equota", "r"); if (!$f) { $msg = 'Cannot create email account. Possible reasons: "fopen" function allowed on your server, PHP is running in SAFE mode'; break; } $msg = "<h2>Email account {$euser}@{$edomain} created.</h2>"; Thank you for the h elp once again I've been developing a php application that runs my entire company for the last 4 years. One of the things I never thought of until now is that the server guys or anyone else could copy the source code and db and be able to start up another company which brings up my question to you.... How would you protect your application? My thought is to create one small php file that is encrypted with something that is required to make the entire site run (not sure at this point what it would be that they couldn't just rebuild). Then if this file sees it's on a different domain/ip it requests data from my site which logs the info for me to look at. If I find out it's something not approved, it would then not allow the program to run and will give a error. What is your idea? I had a programmer who was doing a job for me look over one of my pages and added this security to my POST submit button: Code: [Select] ##### secure ##### if(!empty($_POST['user_url']) & preg_match('/(order.*?by|union.*?select|select.*?from|update.*?set|"|\'|\/*)/', $_POST['user_url'])) exit; if(!empty($_POST['user_url']) & !preg_match('/https?:\/\/[\w\d:#@%\/;$()~\\_?+-=.&]*/', $_POST['user_url'])) exit; ################# However now it doesnt matter what i type into the text box it always Exits the script... can anyone see whats happening here? PS. the purpose the of the text box is to insert URLs into my database... so it would need to allow that format. Hi Little Help Needed I have created a new website In the index.php file i want to show records from database Now, here is how the problem arise I want to import codes from github intead of hosting those files on my server because i want to keep it opensource Below is the code I am using <?php // connect to the database include('connect-db.php'); // get results from database $sql = "SELECT id, upadhi, name FROM munishri"; $result = $conn->query($sql); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { echo "id: " . $row["id"]. " - Name: " . $row["upadhi"]. " " . $row["name"]. "<br>"; } } else { echo "0 results"; } // close connection $conn->close(); ?> Can i host the code to show result in another file and use something like <?php // connect to the database include('connect-db.php'); // get results from database include('http://rawgit.com/th...database.php'); ?> I have a weird kind of problem. I uploaded all upload-directories through FTP which have 777 permissions and owner name 'abc' This means I can access all of them through the codes. But while creating files inside those full permitted directories, the compiler complains for access denied. Meanwhile, a different directory is created with same name whose owner is 'apache' itself and the previous directory is lost. Then I cannot change the permissions of that directory through FTP. I don't if it is apache server's problem itself or not. Or is it a way to define user while creating/editing/deleting files and directories through php code itself? $username = $loggedInUser->username; // This is the logged in username $time = time(); $makedir = $username.'_'.$time; $var = getcwd(); $var = str_replace('\users', '\imageuploads', $var); $dirlocation = $var."\\".test_directory($username, $mysqli); function test_directory ($username, $mysqli) { $stmt = $mysqli->prepare("SELECT Temp_Directory FROM uc_users WHERE user_name LIKE ?"); $stmt->bind_param("s", $username); $stmt->execute(); $stmt->bind_result($Tempdir); while ($stmt->fetch()){ return $Tempdir; } } if((!empty(test_directory($username, $mysqli))) && is_dir($dirlocation)){ //echo "this is it"; $thedirectory = $dirlocation; } if(empty(test_directory($username, $mysqli))){ //echo "it's not a directory"; $newdir = $var."\\".$makedir; $query = mysqli_query($mysqli, "UPDATE uc_users SET Temp_Directory='$makedir' WHERE user_name='$username'"); if(!$query){ //echo mysqli_error($mysqli); } mkdir($newdir); //security chmod($newdir, 0644); $thedirectory = $newdir; } if(!is_dir($dirlocation) && (!empty(test_directory($username, $mysqli)))){ //echo "third one"; mkdir($dirlocation); chmod($dirlocation, 0644); $thedirectory = $dirlocation; } Ok, so what I'm doing here is testing to see whether a a record exists of the user having a folder in the MySQL database. Then, if it does, make sure that a folder exists at that location. If there is no folder, we create one for the user. If there is already a folder, we leave it alone. This is for image uploads, and $thedirectory, is where we upload images later on in the script. Hope that makes sense. The code seems to work. But how can I improve it and make it more robust? Or should I just leave it alone? Should I return FALSE from the function for better reliability over empty()? i am using a Anti MySQL Injection my friend made for me config.php //Anti MySQL Injection function anti_injection($sql) { // removes words that contain sql syntax $sql = preg_replace(sql_regcase("/(from|select|insert|delete|where|drop table|show tables|#|\*|--|\\\\)/"),"",$sql); $sql = trim($sql); // strip whitespace $sql = strip_tags($sql); // strip HTML and PHP tags $sql = addslashes($sql); // quote string with slashes return $sql; } <?php include "./config.php"; $title = $_POST[title]; $type = $_POST[type]; $episode = $_POST[episode]; $year = $_POST[year]; $genre = $_POST[genre]; $status = $_POST[status]; $summary = $_POST[summary]; $pictures = $_POST[pictures]; $title = anti_injection($title); $type = anti_injection($type); $episode = anti_injection($episode); $year = anti_injection($year); $genre = anti_injection($genre); $status = anti_injection($status); $summary = anti_injection($summary); $pictures = anti_injection($pictures); ?> When i enter the data from the text box and click submit it still puts the data in to the date base but it shows ]Notice: Use of undefined constant title - assumed 'title' in C:\wamp\www\studying\take 2\addin11.php on line 41 Notice: Use of undefined constant type - assumed 'type' in C:\wamp\www\studying\take 2\addin11.php on line 42 Notice: Use of undefined constant episode - assumed 'episode' in C:\wamp\www\studying\take 2\addin11.php on line 43 Notice: Use of undefined constant year - assumed 'year' in C:\wamp\www\studying\take 2\addin11.php on line 44 Notice: Use of undefined constant genre - assumed 'genre' in C:\wamp\www\studying\take 2\addin11.php on line 45 Notice: Use of undefined constant status - assumed 'status' in C:\wamp\www\studying\take 2\addin11.php on line 46 Notice: Use of undefined constant summary - assumed 'summary' in C:\wamp\www\studying\take 2\addin11.php on line 47 Notice: Use of undefined constant pictures - assumed 'pictures' in C:\wamp\www\studying\take 2\addin11.php on line 48 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 Deprecated: Function sql_regcase() is deprecated in C:\wamp\www\studying\take 2\config.php on line 30 And thanks to the Anti MySQL Injection my Primary key in my database dont work :s can you help? thank you Using MVC, the controller does some logic, gets data from the model, and the view presents the content.
Where should the reverse be performed?
For instance, I have an edit page which is pre-populated with values from the model, and the view changes 1000 to $1,000, 0.4 to 40%, and 2014-10-09 09:31:41 to 10/09/2014 09:31:41 AM.
Now I need to save the values, and must convert them back to their original format before doing so. Should this functionality be performed in the controller, model, or view?
Thanks
This topic has been moved to PHP Freelancing. http://www.phpfreaks.com/forums/index.php?topic=355195.0 Hi guys, I've been working on a script for a while now, and I'm sure it doesn't look great and all, and it's probably really messed up..

Hello guys, i have a problem that i am trying to solve myself for the entire past week. I am not a php programmer and i wish you can help me. There is a russian project called Crot Anti-Plagiarism, it is a open source moodle plugin. I started to use it and it is a really nice feature. The problem is that there are quite few people that are developing it and new features are coming once a year... I see a big "hole" in this project (at least for me) : The plugin checks for plagiarism in the file that you submit only once, if a student resubmits the file it doesn't see that and you need to start the plugin's test again for all the files which is time consuming if you have a lot of submitted files to check. I would like to add a function that will check if a file changed his modified date , if yes - mark for checking, if no - skip the checking. I already added a similar function that checks if the name has changed, but it seems harder to check it by uploaded time(modified time). Things i have already done: I added a new column "assignment_submissions_timemodified" in database. I added a new function that records the "time modified" of the file in the database. But i can't add and i cannot make the comparison between the date of the first time the file submitted versus the date of the second time the same file was resubmitted. Alright no more bullsh**t here is the code: (there are 3 comments that shows what i've changed, starting with //my job...) Thanks a lot! Code: [Select] $apath= $CFG->dataroot."/$assignment->course/moddata/assignment/$asubmission->assignment/$asubmission->userid"; $timemodified= filemtime($apath); //my job... it checks the file's modified time. $files = scandir($apath, 1); if (! $unprocessedsubm = get_record("crot_submissions", "submissionid", $asubmission->id, "crot_submission_file_name", $files[0], "assignment_submissions_timemodified", $timemodified)) //my job...now i guess here is the problem ( "assignment_submissions_timemodified", $timemodified) { echo "$timemodified"; echo "$unprocessedsubm"; print_r($unprocessedsubm); echo "\nsubmission $asubmission->id was not processed yet. start processing now ... \n" ; $atime = microtime(); $atime = explode(" ",$atime); $atime = $atime[1] + $atime[0]; $astarttime = $atime; if(!count($files))break; //TODO we should verify if filename changed //TODO add loop on the documents folder as well as loop for unzipping $apath = $apath."/$files[0]"; // call tokenizer to get plain text and store it in crot_submissions $atext = tokenizer ($apath); // update the crot_submissions table // delete if exists delete_records("crot_submissions", "submissionid", $asubmission->id); // insert the new record $record->submissionid=$asubmission->id; $record->updated = time(); $record->crot_submission_file_name = $files[0]; $record->assignment_submissions_timemodified = $timemodified; //this is my job.... it is recording the date as it has to. $submid = insert_record("crot_submissions", $record); // insert into documents $docrecord->crot_submission_id = $submid; Also i have attached the whole file crot_crone.php. i have made an delete files script which works for only one directory but not sub directory so i want to delete files of same extention from directory and subdirectory. My current code is Code: [Select] <? $dir = 'hmm/'; function scanr($dir){ $arr = glob($dir.'/*.jpg'); foreach($arr as $vv){ //check if $vv is a file if(is_file($vv)){ //if file, get the filename $vx=explode('/',$vv); $file=$vx[count($vx)-1]; // if no extension delete the file unlink($vv); // print the deletion message echo $vv." deleted!<br>";}else{ // if $vv is a dir then scan it again for files scanr($vv); }} } scanr($dir); ?> I'm trying to echo the directory and sub directory only. I am not looking to show the files contained - only folders. I'm not amazing with PhP, so excuse me if it looks terrible xD I've taken tutorials, edited them to fit my wanting and tried it out, it seems to deny anything other than an image type, but could it be abused?

Is this code secure? (Someone told me I should use a switch statement instead?!) Code: [Select] <?php if (isset($_GET['article'])) { $articleFile = preg_replace('#[^A-z0-9_\-]#', '', $_GET['article']).'.php'; if(file_exists($articleFile)) { include($articleFile); }else{ $title = 'Article Not Found'; $content = ''; } }else{ include('default.php'); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Dynamic Content Example</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link type="text/css" rel="stylesheet" href="css/pagelayout.css"> <link type="text/css" rel="stylesheet" href="css/dropdown.css"> </head> <body> <div id="wrapper" class="clearfix"> <div id="inner"> <div id="header"> <!-- DROP-DOWN MENU --> <ul id="topMenu"> <li class="current"><a href="?article=article1">Article 1</a></li> <li><a href="?article=article2">Article 2</a></li> <li><a href="?article=article3">Article 3</a></li> <!-- and so on... --> </ul><!-- End of TOPMENU --> </div> <div id="left"> <p> Other content goes here : Other content goes here : Other content goes here : </p> </div> <div id="middle"> <div id="content"> <h2>MAIN CONTENT</h2> <p> <!-- Dynamically insert Article here using PHP include!! --> <?php echo $content; ?> </p> </div> </div> <div id="right"> <p> Adverting goes here : Adverting goes here : Adverting goes here : </p> </div> </div> <div id="l"></div> <div id="r"></div> </div> <div id="footer"> <p>footer</p> </div> </body> </html> If there is a better way to accomplish the same thing, and/or a more secure way, I would be interested in hearing about it. Thanks, Debbie OK so I have a page that a user can not access unless they are logged in works great. On that page I have links to documents, if you direct link to those docs they work. They should not unless you are logged in. How can I implement this? I wrote an update script, how secure do you think it is? By the way, this is an include. The page it is included on stop attacks by making sure the user is logged in. function update_file($url, $file) { //Get URL content $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); $data = curl_exec($ch); curl_close($ch); $new_content = $data; //Replace with content from URL file_put_contents($file, $new_content); echo $new_content; } function get_url($file) { $domain = 'http://www.mysite.com/'; $folder = 'update/'; $ver = '2.0.1'; $full_url = ''.$domain.''.$folder.'/'.$ver.'/'; $fileu = array ( "functions/update.php" => "".$full_url."functions/update.txt" ); return $fileu[$file]; } $files = array ( 'functions/update.php' ); foreach($files as $file) { update_file(get_url($file),$file); } Hey guys i am making a php application and i have a feature where it allows members to upload images. If there a way to secure a folder to only be allowed access when a member is logged in and not someone accessing the folder and downloading images. Stuped question i know would it be better to store the images in the database as BLOB? but then again could make the database big. Thanks I have parts of my webpage protected with the following Code: [Select] session_start(); if(!isset($_SESSION['myusername'])){ header("Location:login.php"); } else { $username = $_SESSION['myusername']; } How secure is this? The goal is so people who don't have access to the page (don't have a login account) cannot get access Thanks for any tips |
