Cross-site scripting (XSS) vulnerability in Allegro RomPager before 4.51, as used on the ZyXEL P660HW-D1, Huawei MT882, Sitecom WL-174, TP-LINK TD-8816, and D-Link DSL-2640R and DSL-2641R, when the "forbidden author header" protection mechanism is bypassed, allows remote attackers to inject arbitrary web script or HTML by requesting a nonexistent URI in conjunction with a crafted HTTP Referer header that is not properly handled in a 404 page. NOTE: there is no CVE for a "URL redirection" issue that some sources list separately.

Multiple cross-site request forgery (CSRF) vulnerabilities in Sitecom WLM-2501 allow remote attackers to hijack the authentication of administrators for requests that modify settings for (1) Mac Filtering via admin/formFilter, (2) IP/Port Filtering via formFilter, (3) Port Forwarding via formPortFw, (4) Wireless Access Control via admin/formWlAc, (5) Wi-Fi Protected Setup via formWsc, (6) URL Blocking Filter via formURL, (7) Domain Blocking Filter via formDOMAINBLK, and (8) IP Address ACL Filter via admin/formACL in goform/, different vectors than CVE-2012-1921.

Cross-site request forgery (CSRF) vulnerability in goform/admin/formWlEncrypt in Sitecom WLM-2501 allows remote attackers to hijack the authentication of administrators for requests that change the router passphrase via the pskValue parameter.

The UPnP IGD implementation in Edimax EdiLinux on the Edimax BR-6104K with firmware before 3.25, Edimax 6114Wg, Canyon-Tech CN-WF512 with firmware 1.83, Canyon-Tech CN-WF514 with firmware 2.08, Sitecom WL-153 with firmware before 1.39, and Sweex LB000021 with firmware 3.15 allows remote attackers to execute arbitrary commands via shell metacharacters.

The UPnP IGD implementation in Edimax EdiLinux on the Edimax BR-6104K with firmware before 3.25, Edimax 6114Wg, Canyon-Tech CN-WF512 with firmware 1.83, Canyon-Tech CN-WF514 with firmware 2.08, Sitecom WL-153 with firmware before 1.39, and Sweex LB000021 with firmware 3.15 allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.

The UPnP IGD implementation in Broadcom Linux on the Sitecom WL-111 allows remote attackers to establish arbitrary port mappings by sending a UPnP AddPortMapping action in a SOAP request to the WAN interface, related to an "external forwarding" vulnerability.

Sitecom WL-153 router firmware before 1.38 allows remote attackers to bypass access restrictions and conduct unauthorized operations via a UPnP request with a modified InternalClient parameter, which is not validated, as demonstrated by using AddPortMapping to forward arbitrary traffic.
