Administrator credential disclosure via hex-encoded session cookie
Published Jul 18, 2025 · Updated Jul 18, 2025
Credential disclosure in XXL-JOB 3.1.0 through 3.1.1 allows remote attackers to recover administrator password hashes from captured session cookies. The makeToken method serializes the entire administrator user object, including its MD5 password hash and role data, then converts the JSON bytes directly to reversible hexadecimal for XXL_JOB_LOGIN_IDENTITY. Exploitation requires access to an authenticated administrator cookie, and the published assessment limits the resulting impact to confidentiality.
