ZOC Terminal 7.25.5 contains a denial of service vulnerability in the private key file input field that allows attackers to crash the application. Attackers can overwrite the private key file input with a 2000-byte buffer, causing the application to become unresponsive when attempting to create SSH key files.
Executive ViewAI
ZOC Terminal 7.25.5 contains a denial of service vulnerability that allows attackers to crash the application by exploiting the private key file input field. Organizations using this terminal emulator for SSH access or secure communications face potential service disruptions, and the existence of public exploits elevates the risk of active exploitation.
Disable or restrict access to the private key file import feature in ZOC Terminal settings; implement network segmentation to limit which users/systems can access ZOC Terminal; restrict file upload/import capabilities at the application level; monitor for suspicious .key file submissions; consider blocking ZOC Terminal file inputs at the email/file transfer gateway; evaluate alternative terminal emulator software with active vendor support.
