Description

The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 is vulnerable to stored XSS in the set_banner() function of /var/www/core/controller/index.php. An unauthenticated attacker may set the contents of the /mnt/jffs2/banner.txt file, stored on the device's filesystem, to contain arbitrary JavaScript. The file contents are then used as part of a welcome/banner message presented to unauthenticated users who visit the login page for the web console. This vulnerability does not occur in the older 1.5.x firmware versions.

Affected configurations

• mimosa b5 firmware (<= 2.8.0.3) • mimosa b5c firmware (<= 2.8.0.3) • mimosa c5c firmware (<= 2.8.0.3)
