Cross-site scripting (XSS) vulnerability in cgi-bin/welcome (aka the login page) in Netgear SSL312 PROSAFE SSL VPN-Concentrator 25 allows remote attackers to inject arbitrary web script or HTML via the err parameter in the context of an error page.
NETGEAR (formerly Infrant) ReadyNAS RAIDiator before 4.00b2-p2-T1 beta creates a default SSH root password derived from the hardware serial number, which makes it easier for remote attackers to guess the password and obtain login access.
Heap-based buffer overflow in the wireless driver (WG311ND5.SYS) 2.3.1.10 for NetGear WG311v1 wireless adapter allows remote attackers to execute arbitrary code via an 802.11 management frame with a long SSID.
Buffer overflow in MA521nd5.SYS driver 5.148.724.2003 for NetGear MA521 PCMCIA adapter allows remote attackers to execute arbitrary code via (1) beacon or (2) probe 802.11 frame responses with an long supported rates information element. NOTE: this issue was reported as a "memory corruption" error, but the associated exploit code suggests that it is a buffer overflow.
Stack-based buffer overflow in WG111v2.SYS in NetGear WG111v2 wireless adapter (USB) allows remote attackers to execute arbitrary code via a long 802.11 beacon request.
NETGEAR DG834GT Wireless ADSL router running firmware 1.01.28 allows attackers to cause a denial of service (device hang) via a long string in the username field in the login window.
Netgear 614 and 624 routers, possibly running VXWorks, allow remote attackers to cause a denial of service by sending a malformed DCC SEND string to an IRC channel, which causes an IRC connection reset, possibly related to the masquerading code for NAT environments, and as demonstrated via (1) a DCC SEND with a single long argument, or (2) a DCC SEND with IP, port, and filesize arguments with a 0 value.
NETGEAR WGT624 Wireless DSL router has a default account of super_username "Gearguy" and super_passwd "Geardog", which allows remote attackers to modify the configuration. NOTE: followup posts have suggested that this might not occur with all WGT624 routers.
The backup configuration option in NETGEAR WGT624 Wireless Firewall Router stores sensitive information in cleartext, which allows remote attackers to obtain passwords and gain privileges.
