Vulnerability Details
The official description states: 'External control of a file name in Ivanti Connect Secure before version 22.7R2.4 and Ivanti Policy Secure before version 22.7R1.3 allows a remote authenticated attacker with admin privileges to write arbitrary files.' This vulnerability falls under the CWE-73 classification, indicating a potential weakness in file access control.
With a CVSS 3.1 score of 4.9, the severity is classified as medium. The attack vector is network-based, and the attack complexity is low, requiring high privileges with no user interaction. The integrity impact is high, while confidentiality and availability impacts are noted as none.
Technical Analysis
The root cause of this vulnerability relates to insufficient validation of file names, allowing an attacker to write arbitrary files. The attack vector is network-based, meaning attackers can exploit this vulnerability remotely. The attack complexity is low, indicating that it can be executed with minimal effort. High privileges are required to exploit this vulnerability, yet user interaction is not necessary.
Regarding impacts, the integrity of the system is at high risk due to potential unauthorized modifications to files. Confidentiality impacts are none, indicating that sensitive data is not directly exposed. Availability remains unaffected, suggesting that the system will continue to function despite potential exploits.
Risk & Impact Analysis
Organizations utilizing Ivanti Connect Secure and Ivanti Policy Secure must recognize the real-world risk posed by CVE-2024-38657. The potential for attackers to exploit this vulnerability could lead to significant integrity compromises within those systems.
The urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. Given the low complexity and high privileges required for exploitation, the blast radius could be considerable if exploited in a large network environment.
Organizations should schedule remediation to mitigate the risks associated with this vulnerability effectively. The potential impact on system integrity and the ease of exploitation warrant immediate attention.
