CVE-2025-25256 is a critical vulnerability affecting Fortinet FortiSIEM, specifically versions 7.3.0 through 7.3.1, 7.2.0 through 7.2.5, 7.1.0 through 7.1.7, 7.0.0 through 7.0.3, and all versions before 6.7.9. This vulnerability allows an improper neutralization of special elements used in an OS command, leading to OS Command Injection (CWE-78).
The severity of this vulnerability is rated at 9.8 on the CVSS scale, indicating a critical risk. The potential for exploitation is high, particularly as it allows unauthenticated attackers to execute unauthorized code or commands through crafted CLI requests. Organizations should prioritize patching immediately.
Risk to organizations includes the potential for unauthorized access to systems, data compromise, and the ability to affect the integrity and availability of systems. With a critical exploitability status, it is crucial for organizations to address this vulnerability promptly.
As of now, there is confirmed exploit availability, which raises the urgency for organizations to act swiftly on patching and remediation efforts to prevent possible attacks.
Vulnerability Details
The vulnerability allows attackers to exploit the systems running FortiSIEM through a network attack vector with low attack complexity, requiring no privileges or user interaction. The impact on confidentiality, integrity, and availability is rated as high.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of special elements in the operating system commands. The attack vector is network-based, and the exploitation does not require any user interaction or specific privileges.
This vulnerability represents a significant risk due to its ability to execute arbitrary commands, which can lead to full system compromises. Organizations must maintain vigilance and apply the necessary patches.
Risk & Impact Analysis
