CISA KEV Advisory

Elasticsearch Remote Code Execution Vulnerability

Elasticsearch enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code.

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

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

Elasticsearch's dynamic scripting feature allows remote attackers to execute arbitrary MVEL expressions and Java code. With a very high EPSS score of 0.85557, this vulnerability presents a significant risk of remote code execution.

This vulnerability has been actively exploited in the wild and is listed in CISA's KEV catalog. The ability to execute arbitrary code remotely makes this a severe threat.

Recommended Action

Disable dynamic scripting in Elasticsearch if not essential for operations. Apply all available security updates and configure Elasticsearch securely to prevent remote code execution.

Technical Analysis

CVE-2014-3120 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-2014-3120 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.
