CISA KEV Advisory
Apache Kylin OS Command Injection Vulnerability
Apache Kylin contains an OS command injection vulnerability which could permit an attacker to perform remote code execution.
Apply updates per vendor instructions.
Risk Analysis
Apache Kylin is susceptible to an OS command injection vulnerability, which could allow an attacker to achieve remote code execution. The very high EPSS score of 0.93659 indicates a high probability of exploitation, making this a critical vulnerability. Its inclusion in CISA's KEV confirms that this flaw is actively being exploited.
Active exploitation of this vulnerability has been observed in the wild. The flaw is remotely exploitable, allowing for remote code execution.
Update Apache Kylin to a patched version. Implement strict input validation for commands and consider network segmentation to limit access to Apache Kylin instances.
Technical Analysis
CVE-2020-1956 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-2020-1956 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.
