What is the threat?
This vulnerability arises from improper handling of buffer allocations within Ivanti’s secure access solutions, allowing an attacker with local access to exploit the flaw and execute arbitrary code to elevate privileges, and potentially compromising the entire system.
The vulnerability specifically affects the following versions:
- Ivanti Connect Secure 22.7R2.4 and prior
- Ivanti Policy Secure 22.7R1.2 and prior
- Ivanti Neurons for ZTA gateways 22.7R2.3 and prior
Why is it noteworthy?
The significance of CVE-2025-0283 lies in its potential impact on systems that rely on Ivanti’s solutions for secure access. Although there have been no reports of active exploitation of this vulnerability, it poses a substantial risk if attackers gain local access.
