CVE-2011-4499
HighSummary
Implementacja UPnP IGD w stosie UPnP Broadcom na routerach Cisco Linksys WRT54G, WRT54GS v1-v3 oraz WRT54GS v4 przed określonymi wersjami oprogramowania umożliwia zdalnym atakującym ustanawianie dowolnych mapowań portów poprzez wysłanie akcji UPnP AddPortMapping w żądaniu SOAP do interfejsu WAN. Jest to związane z podatnością na 'zewnętrzne przekazywanie'.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do przejęcia kontroli nad portami routera, co może prowadzić do nieautoryzowanego dostępu do wewnętrznych zasobów sieciowych. To stwarza poważne zagrożenie dla bezpieczeństwa sieci organizacji.
Recommendation
Zaleca się aktualizację oprogramowania routerów do najnowszych wersji, które eliminują tę podatność. Dodatkowo, warto rozważyć wyłączenie funkcji UPnP, jeśli nie jest ona niezbędna.

SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
Original NVD description (English source)
The UPnP IGD implementation in the Broadcom UPnP stack on the Cisco Linksys WRT54G with firmware before 4.30.5, WRT54GS v1 through v3 with firmware before 4.71.1, and WRT54GS v4 with firmware before 1.06.1 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.
