Totolink · Totolink A3002Ru · CVE-2025-5508
**Name of the Vulnerable Software and Affected Versions**
TOTOLINK A3002RU version 2.1.1-B20230720.1011
**Description**
The issue is related to the IP/Port Filtering module of the TOTOLINK A3002RU router's firmware, where the `Comment` parameter is not properly protected, leading to cross-site scripting (XSS) attacks. This can be exploited remotely. The vendor was contacted about the disclosure but did not respond.
**Recommendations**
As a temporary workaround, consider disabling the IP Port Filtering Page until a patch is available. Restrict access to the IP Port Filtering Page to minimize the risk of exploitation. Avoid using the `Comment` argument in the affected page until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
