Swisscom · Swisscom Centro Grande · CVE-2019-19941
**Name of the Vulnerable Software and Affected Versions**
Swisscom Centro Grande versions prior to 6.16.12
**Description**
The issue is related to missing hostname validation, allowing a remote attacker to inject its local IP address as a domain entry in the DNS service of the router via crafted hostnames in DHCP requests, causing XSS.
**Recommendations**
For versions prior to 6.16.12, update to version 6.16.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the DNS service of the router to minimize the risk of exploitation.
