This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a cross-site scripting vulnerability in the password plugin. Error text returned by a password driver was concatenated into the message presented to the user without HTML escaping, so a backend able to influence that text, such as the DirectAdmin API, could inject script into the Roundcube interface. Upstream fixed this in the commit “Fix XSS issue in handling of password driver error responses”, which escapes the driver message before display.

Remediation

Check the references section for vendor advisories and patches from roundcube. Update webmail to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
