CVE-2023-25607 is classified as a high-severity OS Command Injection vulnerability that affects several versions of FortiManager, FortiAnalyzer, and FortiADC. This vulnerability allows authenticated attackers with at least READ permissions on system settings to execute arbitrary commands on the underlying shell due to improper neutralization of special elements used in OS commands.
The CVSS score for this vulnerability is 7.8, indicating a high level of risk. The attack vector is local, meaning that an attacker must have access to the system to exploit the vulnerability. Given the implications of executing arbitrary commands, organizations must take immediate action.
The urgency to address this vulnerability is critical, as it poses significant risks to confidentiality, integrity, and availability. With a high exploitability score, the potential for this vulnerability to be actively targeted by attackers is a serious concern.
Organizations should prioritize patching immediately to mitigate the associated risks.
Vulnerability Details
The vulnerability allows for OS Command Injection due to unsafe usage of the wordexp function in the management interface of Fortinet products. Specifically, it affects FortiManager versions 7.2.0 through 7.2.2, 7.0.0 through 7.0.7, 6.4.0 through 6.4.11, and all versions of 6.2 and 6.0. Similarly, FortiAnalyzer and FortiADC are impacted across various versions.
The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, confirming the severity and potential impact on affected systems.
Technical Analysis
The root cause of CVE-2023-25607 is an improper neutralization of special elements used in OS commands, leading to command injection vulnerabilities. Attackers can exploit this vulnerability by leveraging local access to the management interface.
The attack vector is categorized as local, with a low attack complexity. Privileges required are low, which means even users with minimal access can exploit the vulnerability without any user interaction. The impacts are severe, affecting confidentiality, integrity, and availability, all rated as high.
Risk & Impact Analysis
Risk to organizations includes unauthorized command execution, potentially compromising the entire system. The blast radius is significant given that multiple versions of Fortinet products are affected, making it imperative for organizations to address this vulnerability promptly.
Based on the CVSS score and its implications, organizations should address this vulnerability in their priority patch cycle to ensure operational security.
