Vulnerability Details
The vulnerability in question is a stack-based buffer overflow in Ivanti Connect Secure, which can lead to remote code execution. The official CVE description states that it affects all versions before 22.7R2.6. The vulnerability has a CVSS 3.1 score of 9.9, indicating a critical severity level with high potential impacts on confidentiality, integrity, and availability.
The CWE classification for this vulnerability is CWE-121, which relates to improper control of a resource through its lifetime.
Technical Analysis
The root cause of this vulnerability is a stack-based buffer overflow, which occurs when data overflow past the buffer's boundary and into adjacent memory. This condition can allow an attacker to overwrite the return address on the stack, leading to arbitrary code execution. The attack vector is network-based, and the attack complexity is low, requiring only low privileges for execution. No user interaction is required for exploitation.
The impact of this vulnerability is significant, with high confidentiality, integrity, and availability impacts. Attackers may leverage this vulnerability to gain control over the affected systems and potentially launch further attacks within the network.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22467 is high due to the critical nature of the vulnerability and the potential for exploitation by remote attackers. Organizations using Ivanti Connect Secure are strongly advised to assess their exposure and the potential blast radius should this vulnerability be exploited. The urgency of the situation is underscored by the CVSS score of 9.9, indicating that this should be addressed as a priority.
Organizations should address in priority patch cycle.
