Unauthenticated file read via markId SQL injection
Published Aug 11, 2026 · Updated Aug 11, 2026
SQL injection in Weaver E-cology 8.0 allows remote attackers to read arbitrary server files through the SignatureDownLoad servlet. The servlet concatenates the markId GET parameter into a SQL query, trusts the injected markPath result as a filesystem path, and streams that file in the response. No authentication or user interaction is required; disclosure is limited to files readable by the application server process, including configuration files with database credentials.
