SourceCVE-2023-34987

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

The vulnerability, tracked as CVE-2023-34987, is due to improper neutralization of special elements used in OS commands. This could enable attackers to exploit something called “OS command injection” by crafting malicious HTTP GET requests containing commands.

OS command injection works by inserting operating system commands into input fields. If not sanitized properly, the commands could then get executed by the system with elevated privileges. In this case, an attacker could exploit the FortiWLM tool to run harmful commands on the targeted server.

FortiWLM users are advised to immediately update to the latest versions 8.6.5 or 8.5.4 which have addressed this security issue. It is also recommended to minimize network exposure of the management interface and only allow connections from trusted networks and users.

Proper input validation and output encoding is important for any tool or website that processes external input to prevent exploits like command injection. Keeping systems updated also helps stay protected against the latest vulnerabilities.
