Introduction
Unauthorized code execution on a security appliance can undermine the entire security posture of an organization. CVE-2025-58034 is a high-severity OS command injection vulnerability in Fortinet FortiWeb, potentially allowing authenticated attackers to run arbitrary commands on the underlying system. FortiWeb is Fortinet's dedicated web application firewall, widely deployed to protect web applications from a range of attacks.
Fortinet is a major player in the cybersecurity industry, with a global customer base and a reputation for providing perimeter and application security solutions. The company's products are integral to the security infrastructure of many enterprises, making vulnerabilities in Fortinet appliances especially impactful.
Technical Information
CVE-2025-58034 is categorized under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'). The vulnerability affects FortiWeb versions 8.0.0 through 8.0.1, 7.6.0 through 7.6.5, 7.4.0 through 7.4.10, 7.2.0 through 7.2.11, and 7.0.0 through 7.0.11.
The flaw resides in the way FortiWeb handles input in certain HTTP requests or CLI commands. An authenticated attacker can craft input containing special characters or command sequences that are not properly sanitized by the application. When this input is processed, it can result in execution of arbitrary operating system commands with the privileges of the FortiWeb process.
The root cause is insufficient input validation in the affected components. Exploitation requires a valid authenticated session, which reduces the attack surface but still poses a significant risk, especially in environments where multiple administrators or third-party integrations have access.
No public code snippets or vulnerable code locations have been disclosed. The attack requires knowledge of valid credentials and the ability to send crafted requests to the management interface or CLI.
Affected Systems and Versions
- FortiWeb 8.0.0 through 8.0.1
- FortiWeb 7.6.0 through 7.6.5
- FortiWeb 7.4.0 through 7.4.10
- FortiWeb 7.2.0 through 7.2.11
- FortiWeb 7.0.0 through 7.0.11
All configurations requiring authentication are potentially vulnerable if running these versions.
Vendor Security History
Fortinet has previously addressed multiple critical vulnerabilities in its product lines, including OS command injection and SQL injection flaws. The company is a CVE Numbering Authority and is responsible for assigning CVEs to its own products. Fortinet has faced criticism for silent patching and delayed disclosure, but generally provides patches for supported products. Security teams should monitor Fortinet advisories and apply patches promptly.
