Apache Roller 6.1.5 has an authentication bypass by capture-replay (CWE-294) in its WSSE digest authentication for the AtomPub API. An attacker who obtains a valid WSSE digest authentication header can replay it because the server does not enforce nonce uniqueness or timestamp freshness, and thereby gains the victim's AtomPub authority (high confidentiality and integrity impact, low availability impact; CVSS 3.1 base score 7.7). Only installations that enable the non-default AtomPub API together with WSSE authentication and plaintext-compatible password storage are affected. Apache Roller 6.1.6 and later remove WSSE as an AtomPub authentication method, and existing WSSE configurations fail closed until an administrator chooses a supported method. It is not listed in CISA KEV and no public proof-of-concept is known.
What to do: Upgrade Apache Roller to 6.1.6 or later. After upgrade, installations that were using WSSE fail closed until an administrator explicitly selects a supported AtomPub authentication method; confirm AtomPub is either disabled or no longer using WSSE, and avoid plaintext-compatible password storage.

Description · NVD
Authentication Bypass by Capture-replay in Apache Roller 6.1.5 allows an attacker who captures a valid WSSE digest authentication header to replay it and gain the victim's AtomPub authority, because the authentication does not enforce nonce uniqueness or timestamp freshness. Only installations that enable the non-default AtomPub API with WSSE authentication and plaintext-compatible password storage are affected. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which removes WSSE as an AtomPub authentication method; existing installations configured for WSSE fail closed until an administrator explicitly selects a supported authentication method.
