CVE-2023-34993 Scanner

Fortinet FortiWLM is a wireless network manager used widely in enterprises for managing and optimizing wireless networks. It provides centralized monitoring, reporting, and configuration for wireless network operations. Companies and governmental organizations rely on it to maintain optimal network performance and security. The software supports a variety of devices and is crucial for managing wireless deployments at scale. FortiWLM helps administrators ensure seamless user experiences and network reliability. Security features in FortiWLM are essential for protecting wireless environments against potential threats.

The Command Injection vulnerability identified in Fortinet FortiWLM allows attackers to execute unauthorized code or commands due to improper neutralization of special elements used in OS commands. This critical vulnerability affects versions 8.6.0 through 8.6.5 and 8.5.0 through 8.5.4, posing significant risks of unauthorized access. Bypassing authentication processes through this vulnerability enables attackers to gain control over affected systems. This exposure could lead to full system compromise, data leakage, and further exploitation of network resources. Immediate attention is needed to mitigate the risks associated with this vulnerability.

The technical details of the vulnerability include an improper neutralization mechanism within a CGI script endpoint. Attackers leverage the vulnerability by injecting shell commands in the 'progressfile' parameter via HTTP requests. The lack of sufficient input validation results in the unintended execution of injected OS commands on the server. Successful exploitation is contingent upon network accessibility to the FortiWLM interface. This architecture flaw highlights the critical need to apply input sanitization to prevent unauthorized script execution.

When exploited, the vulnerability can lead to severe consequences, such as full system takeover. Attackers may deploy additional malicious payloads, establish persistent backdoors, or escalate privileges within compromised networks. Data integrity and availability may be compromised, and attackers can intercept sensitive information transmitted across the network. The unauthorized command execution opens avenues for further lateral movement across the attacker's network infrastructure. Mitigating potential impacts requires prompt application of security updates and adherence to best practices for input sanitization.
