CVE-2013-6027

TITLE

D-Link routers authenticate administrative access using specific User-Agent string

Trust: 0.8

sources: CERT/CC: VU#248083

DESCRIPTION

Stack-based buffer overflow in the RuntimeDiagnosticPing function in /bin/webs on D-Link DIR-100 routers might allow remote authenticated administrators to execute arbitrary commands via a long set/runtime/diagnostic/pingIp parameter to Tools/tools_misc.xgi. Various D-Link routers allow administrative web actions if the HTTP request contains a specific User-Agent string. This backdoor allows an attacker to bypass password authentication and access the router's administrative web interface. Planex and Alpha Networks devices may also be affected. The D-Link DIR-100 routers are router devices. Triggers the vulnerability to crash the web interface. Multiple Vendors are prone to a stack-based buffer-overflow vulnerability. Exploiting this vulnerability may allow attackers to execute arbitrary code in the context of the affected devices. The following are vulnerable: D-Link DIR-120 D-Link DI-624S D-Link DI-524UP D-Link DI-604S D-Link DI-604UP D-Link DI-604 D-Link DIR-100 D-Link TM-G5240 PLANEX COMMUNICATIONS BRL-04UR PLANEX COMMUNICATIONS BRL-04R PLANEX COMMUNICATIONS BRL-04CW. The vulnerability is caused by the script's lack of sufficient filtering of the parameters submitted by the user
