A recently discovered vulnerability in FortiTester, a popular network testing and security product, has been assigned the CVE identifier CVE-2022-38372. This issue, classified as a hidden functionality vulnerability (CWE-1242), affects FortiTester Command-Line Interface (CLI) versions 2.3. through 3.9.1, 4.. through 4.2., and 7.. through 7.1.. Specifically, an undocumented command could allow local, privileged users to gain root shell access on the device, enabling them to execute unauthorized commands and compromise overall network security.
Code Snippet
Upon investigation, the vulnerability's origin stems from an undocumented command existing within the FortiTester CLI. The following code snippet demonstrates the unauthorized command:
fortitester> enable_root_shell
By executing this command as a privileged user, like an administrator, the FortiTester CLI provides root shell access to the device. Consequently, gaining unauthorized control over the device's functionalities.
Exploit Details
The primary risk associated with the CVE-2022-38372 hidden functionality vulnerability is the potential for a local, privileged user to exploit the undocumented command and gain root shell access on the device, potentially causing widespread damage. This could lead to unauthorized activities, including but not limited to:
Compromising overall network security infrastructure.
To exploit this vulnerability, an attacker must first gain privileged access to the FortiTester CLI. Once they have access, they can then execute the undocumented command, as demonstrated in the code snippet above.
