Atlassian Confluence Data Center and Server Template Injection Vulnerability

Atlassian Confluence Data Center and Server contain an unauthenticated OGNL template injection vulnerability that can lead to remote code execution.

Added to KEV: 2024-01-24Federal patch deadline: 2024-02-14⚠ USED IN RANSOMWARE CAMPAIGNS

Required Action (CISA)

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Risk Analysis

Atlassian Confluence Data Center and Server are vulnerable to an unauthenticated OGNL template injection, which can lead to remote code execution. This allows an attacker to execute arbitrary code on the affected server without needing to authenticate. This is a high-severity issue with a very high exploitation likelihood (EPSS 0.94363) and is actively exploited.

Active exploitation of this vulnerability has been observed in the wild, and it is listed in CISA's Known Exploited Vulnerabilities Catalog. The flaw is remotely exploitable by an unauthenticated attacker.

Recommended Action

Apply the latest security patches for Atlassian Confluence Data Center and Server to address the OGNL template injection vulnerability. Implement strict input validation and sanitize all user-controlled data.

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-2023-22527 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-2023-22527 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.
