CISA KEV Advisory
Cisco VPN Routers Remote Code Execution Vulnerability
A vulnerability in the web interface of the Cisco VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary code as root and gain full control of an affected system.
Apply updates per vendor instructions.
Risk Analysis
A critical vulnerability in the web interface of Cisco VPN Routers allows an unauthenticated, remote attacker to execute arbitrary code with root privileges, leading to full system compromise. The high EPSS score and confirmed exploitation by CISA indicate a severe and actively exploited threat.
This vulnerability is actively being exploited in the wild. The flaw is remotely exploitable without authentication, making it a high-priority target for attackers.
Administrators should immediately apply available patches or firmware updates for affected Cisco VPN Routers. If patching is not possible, restrict network access to the router's web interface to trusted sources only.
Technical Analysis
CVE-2018-0125 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-2018-0125 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.
