As an enterprise-grade, open-source Document Management System (DMS), SeedDMS relies heavily on PHP to process metadata, manage workflows, and handle file uploads. When these input mechanisms lack strict validation, the platform becomes a prime target for malicious actors looking to compromise corporate data repositories. ⚠️ Core Vulnerability Overview: SeedDMS 5.1.22
Using SQL injection, an attacker might:
The server accepts the input and permanently saves it to the event ledger. Phase 2: Execution and Impact
SeedDMS 5.1.22 contains multiple XSS vectors. Although many documented XSS vulnerabilities affect versions up to 5.1.25, the codebase patterns that allow XSS are likely present in 5.1.22 as well.
SeedDMS versions 5.1.x through 5.1.23 suffer from multiple CSRF vulnerabilities. Attackers can craft a malicious web page that, when visited by an authenticated SeedDMS user, performs unwanted actions on that user's behalf.
When an authenticated admin visits the page, the document is locked without their consent.
