Name of the Vulnerable Software and Affected Versions TN-5900 Series firmware versions v3.3 and prior

Description The issue stems from insufficient input validation and improper authentication in the key-generation function. This could potentially allow malicious users to execute remote code on affected devices. The vulnerability is related to errors in processing input data in the key-generation function, which may enable a remote attacker to execute arbitrary code.

Recommendations For TN-5900 Series firmware versions v3.3 and prior, update to a version later than v3.3 to resolve the issue. As a temporary workaround, consider restricting access to the key-generation function until a patch is available.
