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.

A stored cross‑site scripting (XSS) vulnerability in the Link Aggregation configuration interface allows an unauthenticated remote attacker to create a trunk entry containing malicious HTML/JavaScript code. When the affected page is viewed, the injected script executes in the context of the victim’s browser, enabling unauthorized actions such as interface manipulation. The session cookie is secured by the httpOnly Flag. Therefore an attacker is not able to take over the session of an authenticated user.

A stack-based buffer overflow in the device's Telnet/SSH CLI login routine occurs when a unauthenticated attacker send an oversized or unexpected username input. An overflow condition crashes the thread handling the login attempt, forcing the session to close. Because other CLI sessions remain unaffected, the impact is limited to a low‑severity availability disruption.

A stack-based buffer overflow in the CLI's TFTP file‑transfer command handling allows a low-privileged attacker with Telnet/SSH access to trigger memory corruption by supplying unexpected or oversized filename input. Exploitation results in the corruption of the internal buffer, causing the CLI and web dashboard to become unavailable and leading to a denial of service.

A stack-based buffer overflow in the device's file installation workflow allows a high-privileged attacker to send oversized POST parameters that overflow a fixed-size stack buffer within an internal process, resulting in a DoS attack.
