Fortinet FortiWLM Users Beware of OS Command Injection Vulnerability

CVSScvssV3_1: 9.6

Fortinet FortiWLM, a network monitoring and management tool, is affected by a vulnerability that could allow attackers to execute code on systems running vulnerable versions.

The vulnerability, tracked as CVE-2023-36550, is due to improper neutralization of special elements used in OS commands. This could allow an attacker to craft HTTP GET requests containing malicious parameters that are not sanitized before being used in OS commands on the target system.

By exploiting this, an attacker may be able to run arbitrary commands with the privileges of the vulnerable FortiWLM application. This could lead to the compromise of confidentiality, integrity, and availability of the targeted systems.

All FortiWLM users are advised to immediately update to the latest versions 8.6.5 or 8.5.4 which have fixes for this issue. Users should also carefully check and filter all incoming HTTP parameters to prevent exploitation. Following basic security practices like keeping systems updated and limiting network exposure can help mitigate risks from vulnerabilities like this.

While updates are rolled out, enhanced monitoring of logs and network traffic may help detect any suspicious activity resulting from exploitation of this vulnerability. Staying updated on the latest advisories is also recommended to ensure all security issues are addressed promptly.
