CISA KEV Advisory
Array Networks AG and vxAG ArrayOS Missing Authentication for Critical Function Vulnerability
Array Networks AG and vxAG ArrayOS contain a missing authentication for critical function vulnerability that allows an attacker to read local files and execute code on the SSL VPN gateway.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Array Networks AG and vxAG ArrayOS contain a missing authentication vulnerability that allows attackers to read local files and execute code on the SSL VPN gateway. The very high EPSS score of 0.87179 indicates a strong likelihood of exploitation, and its inclusion in CISA's KEV confirms active exploitation, making this a critical vulnerability for affected VPN gateways.
This vulnerability is actively being exploited in the wild. The lack of authentication for critical functions makes it remotely exploitable.
Organizations using Array Networks AG and vxAG ArrayOS should apply all available security updates immediately. Implement robust authentication mechanisms and restrict access to the SSL VPN gateway.
Technical Analysis
CVE-2023-28461 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-2023-28461 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.
