It has been declared as problematic. Affected by this vulnerability is some unknown processing of the component Link Aggregation Configuration Interface. The manipulation with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. The summary by CVE is: 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. The weakness was released by Gabriele Quagliarella as VDE-2025-104. It is possible to read the advisory at certvde.com. This vulnerability is known as CVE-2026-22322 since 01/07/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1059.007 according to MITRE ATT&CK. Upgrading to version 3.53 eliminates this vulnerability. The vulnerability is also documented in the databases at EUVD (EUVD-2026-12791) and CERT Bund (WID-SEC-2026-0765).
