Second Order Command-injection Vulnerability in the Certificate-generation Function
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
TN-4900 Series firmware versions v1.2.4 and prior and TN-5900 Series firmware versions v3.3 and prior are vulnerable to the command-injection vulnerability. This vulnerability stems from insufficient input validation in the certificate-generation function, which could potentially allow malicious users to execute remote code on affected devices.
