CISA KEV Advisory

Apache Struts Improper Input Validation Vulnerability

Apache Struts allows remote attackers to execute arbitrary Object-Graph Navigation Language (OGNL) expressions.

Added to KEV: 2022-03-25Federal patch deadline: 2022-04-15

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

Apache Struts allows remote attackers to execute arbitrary Object-Graph Navigation Language (OGNL) expressions. The high EPSS score of 0.94328 indicates a very high likelihood of exploitation, making this a severe vulnerability. This vulnerability is confirmed as exploited by CISA.

This vulnerability is actively exploited in the wild and is included in CISA's KEV catalog. The ability to execute OGNL expressions remotely makes it a highly exploitable flaw.

Recommended Action

Upgrade Apache Struts to a patched version that addresses the OGNL expression execution vulnerability. Implement input validation and consider using a web application firewall to filter malicious requests.

Technical Analysis

CVE-2013-2251 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2013-2251 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
