Hesk · Hesk · CVE-2020-13992
**Name of the Vulnerable Software and Affected Versions**
Mods for HESK versions 3.1.0 through 2019.1.0
**Description**
The issue allows remote unauthenticated attackers to abuse a helpdesk user's logged in session through a Stored XSS attack. This can occur when a user with sufficient privileges to change their login-page image opens a crafted ticket.
**Recommendations**
For versions 3.1.0 through 2019.1.0, consider restricting access to the login-page image change functionality until a fix is available. As a temporary workaround, avoid opening crafted tickets to minimize the risk of exploitation.
