CVE-2019-12970 (opens in a new tab)How to fix?
Upgrade Debian:8 squirrelmail to version 2:1.4.23~svn20120406-2+deb8u4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream squirrelmail package and not the squirrelmail package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
XSS was discovered in SquirrelMail through 1.4.22 and 1.5.x through 1.5.2. Due to improper handling of RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be bypassed. Malicious script content from HTML e-mail can be executed within the application context via crafted use of (for example) a NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA element.
