> Unauthenticated remote code execution in Ivanti Connect Secure, Policy Secure, and ZTA gateways; CVE-2025-0282 is actively exploited.

Ivanti has disclosed multiple vulnerabilities in its remote access and network access control products, with the most critical being a stack-based buffer overflow in Ivanti Connect Secure (before 22.7R2.5), Ivanti Policy Secure (before 22.7R1.2), and Ivanti Neurons for Zero Trust Access gateways (before 22.7R2.3). CVE-2025-0282 allows unauthenticated remote attackers to achieve remote code execution by exploiting the buffer overflow in a public-facing application, leading to execution in system context. A second vulnerability, CVE-2025-0283, is a similar stack-based buffer overflow affecting the same products that requires local authenticated access but allows privilege escalation. Ivanti has confirmed active exploitation of CVE-2025-0282 in the wild. An attacker gaining code execution could install programs, modify or delete data, and escalate privileges depending on the system's privilege context. Immediate patching is critical for all affected systems, particularly those exposed on the internet.
