Information disclosure via external XML entities
Published Apr 8, 2021 · Updated Aug 4, 2024
XXE in Forcepoint Web Security Content Gateway before 8.5.4 allows remote attackers to disclose information through crafted XML input. The XML processor resolves attacker-supplied external entity URLs and incorporates resources outside its intended control into processed output. No authentication or user interaction is required, and exploitation exposes data readable by the parser without altering it or interrupting service.
