CISA KEV Advisory
Atlassian Bitbucket Server and Data Center Command Injection Vulnerability
Multiple API endpoints of Atlassian Bitbucket Server and Data Center contain a command injection vulnerability where an attacker with access to a public Bitbucket repository, or with read permissions to a private one, can execute code by sending a malicious HTTP request.
Apply updates per vendor instructions.
Risk Analysis
Multiple API endpoints in Atlassian Bitbucket Server and Data Center are susceptible to a command injection vulnerability. An attacker with specific repository access can execute arbitrary code, posing a high risk. The high EPSS score and confirmed exploitation highlight the critical nature of this flaw.
This vulnerability is actively exploited in the wild and is listed in CISA's KEV catalog, confirming its use by threat actors. Exploitation requires an attacker to have access to a public Bitbucket repository or read permissions to a private one, and involves sending a malicious HTTP request.
Atlassian Bitbucket Server and Data Center users should apply the latest security updates to patch this command injection vulnerability. Restricting repository access and monitoring for unusual HTTP requests can also help mitigate risk.
Technical Analysis
CVE-2022-36804 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-2022-36804 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.
