Multiple Schneider Electric Telecontrol products are prone to an HTML-injection vulnerability because they fail to sufficiently sanitize user-supplied data before it is used in dynamic content.

Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials and control how the site is rendered to the user; other attacks are also possible.

The following products are affected:

Schneider Electric Telecontrol Kerweb versions prior to 3.0.1
Schneider Electric Telecontrol Kerwin versions prior to 6.0.1
