CISA KEV Advisory

Apache Struts Remote Code Execution Vulnerability

Forced Object-Graph Navigation Language (OGNL) evaluation in Apache Struts, when evaluated on raw user input in tag attributes, can lead to remote code execution.

Added to KEV: 2021-11-03Federal patch deadline: 2022-05-03

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This vulnerability in Apache Struts allows for remote code execution due to improper handling of user input in tag attributes, leading to forced OGNL evaluation. This is a high-severity issue with a very high exploitation likelihood (EPSS 0.94376) and is confirmed to be actively exploited.

This vulnerability is actively exploited in the wild and is listed in CISA's Known Exploited Vulnerabilities Catalog. The flaw can be remotely exploited through crafted user input.

Recommended Action

Upgrade Apache Struts to a patched version to address the OGNL evaluation vulnerability. Implement input validation and sanitize all user-supplied data before processing.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2020-17530 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-2020-17530 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.
