CVE-2025-0282 is a critical stack-based buffer overflow vulnerability affecting Ivanti Connect Secure, Ivanti Policy Secure, and Ivanti Neurons for Zero Trust Access gateways. This vulnerability allows a remote unauthenticated attacker to achieve remote code execution. The CVSS score for this vulnerability is 9, categorizing it as critical. The high severity level is significant because it indicates a serious risk to organizations using these affected products.
Exploitation of this vulnerability is particularly concerning due to its potential impact. Attackers may leverage this flaw to execute arbitrary code on vulnerable systems without authentication, leading to unauthorized access and control over the affected devices. Given the critical nature of this vulnerability, organizations should prioritize patching immediately.
The vulnerability was published on January 8, 2025, and is under active analysis. It affects multiple versions of Ivanti products, making it essential for organizations to assess their environments and apply necessary updates promptly.
Organizations should also monitor for any signs of exploitation and prepare their incident response plans accordingly.
Vulnerability Details
This vulnerability allows a remote unauthenticated attacker to achieve remote code execution due to a stack-based buffer overflow present 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.
The CVSS score is 9, indicating critical severity. The attack vector is network-based, with high attack complexity and no privileges required for exploitation. User interaction is not necessary, which increases the risk factor.
CWE classifications for this vulnerability include CWE-121 (Stack-based Buffer Overflow) and CWE-787 (Out-of-bounds Write).
Technical Analysis
The root cause of CVE-2025-0282 lies in improper handling of input data, which leads to a stack-based buffer overflow. This vulnerability can be exploited via network access, allowing attackers to send specially crafted requests that exceed the memory bounds of the application.
The attack complexity is rated as high due to the need for precise conditions for successful exploitation, but the lack of authentication makes it highly dangerous. No user interaction is required, which allows attackers to launch attacks remotely without any direct access to the system.
The impact of the vulnerability encompasses confidentiality, integrity, and availability, all rated as high. Successful exploitation could lead to unauthorized access to sensitive information and complete compromise of the affected systems.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized remote code execution, which could lead to data breaches, service disruptions, and significant reputational damage. The blast radius of this vulnerability is extensive, impacting multiple products within the Ivanti ecosystem. Given the critical nature of the CVSS score, organizations should address this vulnerability in their priority patch cycle.
The vulnerability is included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it is actively being targeted by threat actors. Organizations should take immediate action to mitigate the risks associated with this vulnerability.
