CVE-2007-4556 describes a critical vulnerability in OpenSymphony XWork (versions before 1.2.3 and 2.x before 2.0.4), also used in WebWork and Apache Struts, where enabling altSyntax allows remote attackers to execute arbitrary code or cause a denial of service. This is due to the recursive evaluation of form input as an OGNL expression, triggered by specific input sequences. With a CVSS score of 6.8 (medium severity), it has a high FAUCET Risk Score of 86/100, indicating a significant threat with network-based attacks and medium complexity. While there's no evidence of active exploitation in the wild or Metasploit modules, Nuclei templates exist for Remote Code Execution, and there is minimal community discussion or media coverage.
