Technical details
A stored Cross-Site Scripting (XSS) vulnerability exists in the SonicWall Email Security appliance due to improper neutralization of user-supplied input during web page generation (CWE-79). The vulnerability is reachable over the network but requires high privileges, specifically an authenticated administrator account. An attacker can inject malicious JavaScript into the application's database, which is then executed in the context of another user's session when they navigate to the affected page. This could lead to session hijacking or unauthorized configuration changes. The issue affects versions 10.0.34.8215, 10.0.34.8223, and earlier; users should update to version 10.0.35.8405 or later.
