Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in 3com – Asesor de Cookies para normativa española plugin <= 3.4.3 versions.

The web management interface in 3Com Wireless 8760 Dual Radio 11a/b/g PoE Access Point allows remote attackers to cause a denial of service (device crash) via a malformed HTTP POST request.

The 3Com 3CRWER100-75 router with 1.2.10ww software, when enabling an optional virtual server, configures this server to accept all source IP addresses on the external (Internet) interface unless the user selects other options, which might expose the router to unintended incoming traffic from remote attackers, as demonstrated by setting up a virtual server on port 80, which allows remote attackers to access the web management interface.

The 3Com 3CRWER100-75 router with 1.2.10ww software, when remote management is disabled but a web server has been configured, serves a web page to external clients, which might allow remote attackers to obtain information about the router's existence and product details.

Unspecified vulnerability in TOS 2.1.x, 2.2.x before 2.2.5, and 2.5.x before 2.5.2 on TippingPoint IPS allows remote attackers to avoid detection by sending certain fragmented packets.

TippingPoint IPS before 20070710 does not properly handle a hex-encoded alternate Unicode '/' (slash) character, which might allow remote attackers to send certain network traffic and avoid detection, as demonstrated by a cmd.exe attack.

The 3Com IntelliJack Switch NJ220 before 2.0.23 allows remote attackers to cause a denial of service (reboot and reporting outage) via a loopback packet with zero in the length field.

Cross-site scripting (XSS) vulnerability in cgi-bin/admin in 3Com OfficeConnect Secure Router with firmware 1.04-168 allows remote attackers to inject arbitrary web script or HTML via the tk parameter.

The 3Com TippingPoint IPS do not properly handle certain full-width and half-width Unicode character encodings in an HTTP POST request, which might allow remote attackers to evade detection of HTTP traffic.

3Com TippingPoint IPS allows remote attackers to cause a denial of service (device hang) via a flood of packets on TCP port 80 with sequentially increasing source ports, related to a "badly written loop." NOTE: the vendor disputes this issue, stating that the product has "performed as expected with no DoS emerging.
