Account impersonation via Samba credential-file injection
Published Jun 22, 2022 · Updated Aug 3, 2024
Authentication bypass in OpenAM before 14.6.6 allows remote attackers to impersonate users through the Windows NT module. NT.process writes the submitted password to an smbclient authentication file without escaping control characters, so an injected newline adds a later username directive that Samba prefers. Exploitation requires valid Windows NT credentials for one account and grants an OpenAM session for the selected target account.
