Summary of CVE-2025-0282 and CVE-2025-0283

CVE-2025-0282

The CVE-2025-0282 vulnerability is a critical security flaw that enables remote unauthenticated attackers to execute arbitrary code on vulnerable Ivanti appliances. This stack-based buffer overflow occurs in the pre-authentication stage, meaning attackers can potentially compromise the system without requiring any valid credentials.

The vulnerability stems from improper boundary checking in a critical network-facing component of the Ivanti Connect Secure, Policy Secure, and ZTA Gateways. By crafting specially manipulated network packets, an attacker can overflow a stack buffer, overwrite memory contents, and ultimately execute malicious code with system-level privileges.

Potential exploitation scenarios include:

CVE-2025-0283

CVE-2025-0283 is a high-severity vulnerability that allows a local authenticated attacker to escalate their privileges within the Ivanti appliance. This stack-based buffer overflow occurs after successful authentication, enabling malicious users to gain elevated system access.

The vulnerability exploits a memory management flaw in the application's privilege management system. By manipulating specific input parameters, an authenticated user can potentially execute code with higher privileges, potentially compromising the entire system's security model.

Key exploitation risks include:

Ivanti has confirmed limited exploitation of CVE-2025-0282 on Connect Secure appliances and recommends immediate mitigation through patching and integrity checking.
