Doc Text:
A flaw was found in DLP. The application fails to validate file paths supplied to the evidence file endpoint, resulting in a Server-Side Request Forgery (SSRF) vulnerability. An authenticated remote attacker can submit an arbitrary Universal Naming Convention (UNC) network path, forcing the server to initiate Server Message Block (SMB) authentication to an external system. This flaw can lead to information disclosure by allowing the attacker to capture sensitive network authentication credentials.

Description OSIDB Bzimport 2026-11-05 22:06:48 UTC
Server side request forgery vulnerability exists in the DLP on-prem extensions version 11.13.1 and earlier allows the file Prefix parameter in the OpenEventEvidenceFile.do endpoint accepts arbitrary UNC paths without validation. The server-side code attempts to open the specified file path, causing Windows to resolve the hostname and initiate SMB authentication to the attacker-controlled host.
