Web application vulnerabilities

move_uploaded_file in PHP does not does not check for the base directory (open_basedir), which could allow remote attackers to upload files to unintended locations on the system.

PHP 4.2.0 and 4.2.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an HTTP POST request with certain arguments in a multipart/form-data form, which generates an error condition that is not properly handled and causes improper memory to be freed.

PHP, when not configured with the "display_errors = Off" setting in php.ini, allows remote attackers to obtain the physical path for an include file via a trailing slash in a request to a directly accessible PHP program, which modifies the base path, causes the include directive to fail, and produces an error message that contains the path.

Safe Mode feature (safe_mode) in PHP 3.0 through 4.1.0 allows attackers with access to the MySQL database to bypass Safe Mode access restrictions and read arbitrary files using "LOAD DATA INFILE LOCAL" SQL statements.

PHP 4.0 through 4.1.1 stores session IDs in temporary files whose name contains the session ID, which allows local users to hijack web connections.

Buffer overflows in (1) php_mime_split in PHP 4.1.0, 4.1.1, and 4.0.6 and earlier, and (2) php3_mime_split in PHP 3.0.x allows remote attackers to execute arbitrary code via a multipart/form-data HTTP POST request when file_uploads is enabled.

PHP 4.0.4pl1 and 4.0.5 in safe mode allows remote attackers to read and write files owned by the web server UID by uploading a PHP script that uses the error_log function to access the files.

PHP 4.0.5 through 4.1.0 in safe mode does not properly cleanse the 5th parameter to the mail() function, which allows local users and possibly remote attackers to execute arbitrary commands via shell metacharacters.

PHP Apache module 4.0.4 and earlier allows remote attackers to bypass .htaccess access restrictions via a malformed HTTP request on an unrestricted page that causes PHP to use those access controls on the next page that is requested.

The Apache module for PHP 4.0.0 through PHP 4.0.4, when disabled with the 'engine = off' option for a virtual host, may disable PHP for other virtual hosts, which could cause Apache to serve the source code of PHP scripts.

PHP 3 and 4 do not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands by triggering error messages that are improperly written to the error logs.

The file upload capability in PHP versions 3 and 4 allows remote attackers to read arbitrary files by setting hidden form fields whose names match the names of internal PHP script variables.

PHP3 with safe_mode enabled does not properly filter shell metacharacters from commands that are executed by popen, which could allow remote attackers to execute commands.

CGI PHP mylog script allows an attacker to read any file on the target server.

php.cgi allows attackers to read any file on the system.

Buffer overflow in PHP cgi program, php.cgi allows shell access.
