System Information Library for Node.JS Command Injection
In this vulnerability, an attacker can send a malicious payload that will exploit the name parameter. After successful exploitation, attackers can execute remote.
Apply updates per vendor instructions.
Risk Analysis
This vulnerability allows an attacker to execute remote code by sending a malicious payload that exploits the 'name' parameter. The high EPSS score of 0.93933 indicates a very high likelihood of exploitation, and its presence in CISA's KEV confirms active exploitation.
This vulnerability is actively being exploited in the wild. It is remotely exploitable.
Apply the necessary security updates to address this remote code execution vulnerability.
Technical Analysis
CVE-2021-21315 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-2021-21315 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.
