Cisco Confirms Active Exploits Targeting Vulnerabilities in ISE, Leading to Unauthenticated Root Access

On July 22, 2025, Cisco updated its advisory regarding several recently disclosed security vulnerabilities in its Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC), confirming that they are being actively exploited. Cisco’s Product Security Incident Response Team (PSIRT) reported awareness of attempts to exploit these vulnerabilities in real-world scenarios. However, the company did not specify which vulnerabilities are being targeted, the identity of the attacking entities, or the scale of these activities. Cisco ISE is crucial for network access control, determining which users and devices can access corporate networks and under what conditions. A breach at this level could allow attackers unrestricted access to internal systems, effectively bypassing authentication and logging controls and transforming a key policy engine into an unguarded entry point. The alert emphasizes that the identified vulnerabilities are classified as critical.

Critical Infrastructure / Cyber Attack

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced on Monday that there are no signs indicating the recent cyber attack on the Treasury Department has affected other federal agencies. CISA is collaborating closely with the Treasury Department and BeyondTrust to fully understand the breach and reduce its effects. CISA emphasized, “The security of federal systems and the data they safeguard is crucial to our national security. We are taking proactive measures to prevent any further repercussions and will provide updates as needed.” This statement follows the Treasury Department’s disclosure of being targeted in a “major cybersecurity incident” involving Chinese state-sponsored actors, which enabled remote access to certain computers and unclassified documents. The incident, revealed in early December 2024, stemmed from a breach in BeyondTrust’s systems, allowing adversaries to gain sensitive access.
