CISA KEV Advisory

Apache Tomcat Remote Code Execution Vulnerability

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

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

Apache Tomcat is vulnerable to arbitrary code execution through the upload of a specially crafted JSP file. Once uploaded, requesting the JSP file executes any contained code. The high EPSS score of 0.94356 indicates a very high likelihood of exploitation, and it is confirmed to be actively exploited as per CISA's KEV catalog.

This vulnerability is actively exploited in the wild. The flaw allows for remote code execution by uploading and then requesting a malicious JSP file.

Recommended Action

Update Apache Tomcat to a patched version to prevent the upload and execution of malicious JSP files. Configure Tomcat to restrict file uploads and enforce strict access controls on web application directories.

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-2017-12617 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-2017-12617 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.
