CRITICAL 9.8

Apache Roller: Unauthenticated deserialization in the XML-RPC endpoint

CVSS Score
9.8
EPSS Score
0.0%
EPSS Percentile
0th

Deserialization of Untrusted Data in Apache Roller 6.1.5 allows an unauthenticated remote attacker to cause deserialization of attacker-controlled bytes, because the XML-RPC endpoint accepts vendor extension types that are deserialized during request parsing, before authentication. The servlet is mapped unconditionally, so parsing occurs even when the global XML-RPC feature is set to disabled; no non-default configuration is required for this path. This can lead to remote code execution. Users are recommended to upgrade to Apache Roller 6.1.6 or later, which disables the extension types and rejects requests when the XML-RPC feature is disabled.
