NTLMv2 hash exposure via undisclosed SSRF
Published Mar 28, 2024 · Updated Aug 2, 2024
SSRF in SysAid On-Premises before 23.2.14 b18 allows remote authenticated users to expose the local OS user's NTLMv2 hash. Public records do not identify the affected endpoint or explain how attacker-controlled input causes the server to initiate NTLM authentication. Administrative privileges are required, and the disclosed consequence is capture of the local OS user's reusable challenge-response material rather than direct password disclosure.
