A cross-site scripting (XSS) vulnerability exists in Alinto SOGo, version 5.12.7. A maliciously crafted ICS calendar invitation files allows arbitrary JavaScript execution within the authenticated SOGo webmail session. The issue occurs because SVG content embedded in the description field of an ICS file, with an onrepeat event handler, is insufficiently sanitized before being rendered in the webmail interface. A remote attacker can execute JavaScript in the victim's browser when the malicious calendar invite is viewed. Successful exploitation may allow mailbox access, email and contact theft, session hijacking, and other actions allowed by an authenticated user.

SOGo before 5.12.7, when PostgreSQL or MariaDB is used, and cleartext passwords are stored, allows SQL injection. This is related to c_password = '%@' in changePasswordForLogin.

SOGo before 5.12.7, when PostgreSQL is used, allows SQL injection.

SOGo before 5.12.5 does not renew the OTP if a user disables/enables it, and has a too short length (only 12 digits instead of the 20 recommended).

SOGo before 5.12.5 is prone to a XSS vulnerability with events, tasks, and contacts categories.

A vulnerability was identified in Alinto SOGo 5.12.3/5.12.4. This impacts an unknown function. The manipulation of the argument hint leads to cross site scripting. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
