Vulnerability Title
Cross‑Site Request Forgery in Link Aggregation Configuration
Source: NVD (National Vulnerability Database)
Vulnerability Description
A CSRF vulnerability in the Link Aggregation configuration interface allows an unauthenticated remote attacker to trick authenticated users into sending unauthorized POST requests to the device by luring them to a malicious webpage. This can silently alter the device’s configuration without the victim’s knowledge or consent. Availability impact was set to low because after a successful attack the device will automatically recover without external intervention.
