CISA KEV Advisory
Ivanti Connect Secure and Policy Secure Authentication Bypass Vulnerability
Ivanti Connect Secure (ICS, formerly known as Pulse Connect Secure) and Ivanti Policy Secure gateways contain an authentication bypass vulnerability in the web component that allows an attacker to access restricted resources by bypassing control checks. This vulnerability can be leveraged in conjunction with CVE-2024-21887, a command injection vulnerability.
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Ivanti Connect Secure (ICS) and Ivanti Policy Secure gateways have an authentication bypass vulnerability in their web component. This allows an attacker to access restricted resources without proper authentication, and can be chained with other vulnerabilities for further compromise. This is a high-severity issue with a very high exploitation likelihood (EPSS 0.94367) and is actively exploited.
This vulnerability is actively exploited in the wild and is included in CISA's Known Exploited Vulnerabilities Catalog. It is remotely exploitable, allowing attackers to bypass authentication.
Apply the latest security updates for Ivanti Connect Secure and Ivanti Policy Secure gateways. Implement multi-factor authentication and monitor for suspicious access attempts.
Technical Analysis
CVE-2023-46805 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-2023-46805 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.
