Seeddms 5.1.22 Exploit __exclusive__ [ Web FAST ]

: Eliminate excessive access rules that permit standard system accounts to invoke binary execution utilities without valid security passwords.

The vulnerability exists in the out/out.html.php file, which does not properly validate user input. An attacker can exploit this vulnerability by sending a crafted request to the server, allowing them to include arbitrary files and execute PHP code.

Testers identified that an authenticated user could abuse the document upload feature to execute arbitrary system commands. This often mirrors CVE-2019-12744

SeedDMS 5.1.22 allows an authenticated user with "Manage Tools" permission to modify the settings.php file content via the "Custom Setup" interface ( out/out.BackupTools.php ). The parameter $settings is written to conf/settings.php without adequate filtering of PHP code. seeddms 5.1.22 exploit

is a popular open-source Document Management System (DMS) based on PHP and MySQL, widely used for organizing documents, managing versions, and controlling access. While it offers robust functionality, older versions, particularly SeedDMS 5.1.22 , have been found to contain severe security vulnerabilities that, if exploited, can lead to full system compromise.

To demonstrate the exploit, we created a proof-of-concept (PoC) payload that injects a malicious SQL query to extract sensitive information from the database. : Eliminate excessive access rules that permit standard

The core flaw in SeedDMS 5.1.22 stems from inadequate validation of uploaded file extensions and insufficient restrictions within the document storage architecture.

SeedDMS version 5.1.22 has been associated with various security vulnerabilities, most notably those involving Remote Command Execution (RCE) Testers identified that an authenticated user could abuse

Similar to CVE-2019-12744 , which allows authenticated users with file upload privileges to execute PHP code by uploading a malicious file.

In version 5.1.22, the application fails to restrict executable extensions (such as .php , .php5 , or .phtml ) under certain configurations, or it allows users to bypass front-end checks. If an attacker uploads a malicious PHP script disguised as a standard document, the server saves it. If the upload directory is web-accessible—or if the file can be reached via a local file inclusion/path traversal vulnerability—the attacker can trigger the execution of the PHP code by navigating directly to the file's URL.
