OpenCATS vulnerabilities

OpenCATS prior to 0.10.0, in the Import module (modules/import/ImportUI.php), can preserve an uploaded file's original name for one import data type and place the file in the web-accessible temporary directory. An authenticated user with Import privileges can select the affected import path and upload a PHP file that remains under an attacker-controlled executable filename, and an import error can leave the file on disk. If the temporary directory is served with PHP execution enabled, requesting the staged file can execute arbitrary PHP code with the web server process privileges. This issue is fixed in version 0.10.0.

OpenCATS 0.9.4 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands by uploading malicious PHP files disguised as resume attachments.

OpenCATS prior to commit 3002a29 contains a PHP code injection vulnerability in the installer AJAX endpoint that allows unauthenticated attackers to execute arbitrary code by injecting PHP statements into the databaseConnectivity action parameter. Attackers can break out of the define() string context in config.php using a single quote and statement separator to inject malicious PHP code that persists and executes on every subsequent page load when the installation wizard remains incomplete.

OpenCATS from version 0.9.1a contains an SQL injection vulnerability in DataGrid filter handling that allows authenticated attackers to inject SQL through crafted filters targeting the non-filterable Tags column in the Candidates DataGrid. Attackers can bypass column filterable restrictions by manipulating filter requests to execute arbitrary SQL queries against the database.

OpenCATS up to version 0.9.7.4 contains an SQL injection vulnerability in the sortDirection parameter of the DataGrid component. Authenticated users can inject malicious SQL via the sortDirection parameter in ajax/getDataGridPager.php to perform time-based blind injection attacks and extract sensitive database contents.
