CyberRota Analysis

AI-Generated

Apache Roller 6.1.5 is vulnerable to a critical deserialization flaw that allows unauthenticated remote attackers to execute arbitrary code by sending specially crafted XML-RPC requests. This vulnerability exists due to the unconditional mapping of the XML-RPC endpoint, which processes requests even when the feature is disabled. Organizations using this version of Apache Roller should prioritize upgrading to version 6.1.6 or later to mitigate the risk of remote code execution.

Original NVD Description

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.
