Cross-site request forgery (CSRF) vulnerability in /xslt in 2wire 1701HG, 1800HW, and 2071 Gateway routers, with 3.17.5, 3.7.1, and 5.29.51 software, allows remote attackers to create DNS mappings as administrators, and conduct DNS poisoning attacks, via the NAME and ADDR parameters.

Cross-site request forgery (CSRF) vulnerability in the xslt script in the web-based management interface on the 2wire 1701HG, 1800HW, 2071HG, and 2700HG with firmware 3.17.5, 3.7.1, 4.25.19, or 5.29.51 allows remote attackers to hijack the intranet connectivity of arbitrary users for requests that cause a denial of service (network outage) via a page parameter with a % (percent) character followed by a non-alphanumeric character.

The management interface on the 2wire Gateway 1700HG, 1701HG, 1800HW, 2071, 2700HG, and 2701HG-T with software before 5.29.52 allows remote attackers to cause a denial of service (reboot) via a %0d%0a sequence in the page parameter to the xslt program on TCP port 50001, a related issue to CVE-2006-4523.
