CVE-2019-19551: Sangoma FreePBX

Medium severity, CVSS 4.8. EPSS: 0.6% chance of exploitation in the next 30 days.

In userman 13.0.76.43 through 15.0.20 in Sangoma FreePBX, XSS exists in the User Management screen of the Administrator web site. An attacker with access to the User Control Panel application can submit malicious values in some of the time/date formatting and time-zone fields. These fields are not being properly sanitized. If this is done and a user (such as an admin) visits the User Management screen and views that user's profile, the XSS payload will render and execute in the context of the victim user's account.

Affected products

• Sangoma FreePBX: from 13.0, up to and including 13.0.76.43; from 14.0, up to and including 14.0.7; from 15.0, up to and including 15.0.20
