A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.5, Ivanti Policy Secure before version 22.7R1.2, and Ivanti Neurons for ZTA gateways before version 22.7R2.3 allows a remote unauthenticated attacker to achieve remote code execution.
Exploitation Walkthrough and Techniques - Ivanti Connect Secure RCE (CVE-2025-0282)
We agree - modern security engineering is hard - but none of this is modern. We are discussing vulnerability classes - with no sophisticated trigger mechanisms that fuzzing couldnt find - discovered in the 1990s, that can be trivially discovered via basic fuzzing, SAST (the things product security teams do with real code access). As an industry, should we really be communicating that these vulnerability classes are simply too complex for a multi-billion dollar technology company that builds enterprise-grade, enterprise-priced network security solutions to proactively resolve?
How Memory Forensics Revealed Exploitation of Ivanti Connect Secure VPN Zero-Day Vulnerabilities
Volexity regularly prioritizes memory forensics when responding to incidents. This strategy improves investigative capabilities in many ways across Windows, Linux, and macOS. This blog post highlights some specific ways memory forensics played a key role in determining how two zero-day vulnerabilities were being chained together to achieve unauthenticated remote code execution in Ivanti Connect Secure VPN devices.
Ivanti Connect Secure VPN Exploitation Goes Global
On January 10, 2024, Volexity publicly shared details of targeted attacks by UTA00178 exploiting two zero-day vulnerabilities (CVE-2024-21887 and CVE-2023-46805) in Ivanti Connect Secure (ICS) VPN appliances. On the same day, Ivanti published a mitigation that could be applied to ICS VPN appliances to prevent exploitation of these vulnerabilities. Since publication of these details, Volexity has continued to monitor its existing customers for exploitation. Volexity has also been contacted by multiple organizations that saw signs of compromise by way of mismatched file detections. Volexity has been actively working multiple new cases of organizations with compromised ICS VPN appliances.
