This vulnerability has a CVSS 3.1 base score of 6.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from mimosa. Update b5_firmware 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.
