Information disclosure via reflected parser errors
Published May 26, 2026 · Updated May 26, 2026
Information disclosure in SAP Gateway allows remote authenticated users to reveal request artifacts through crafted error messages. The Gateway URI error-handling path reflects attacker-controlled request content and internal parsing artifacts in returned messages. Authenticated access is required, and the disclosed regex patterns and URI-parsing logic affect confidentiality without altering data or interrupting service.
