Descriptions

D-Link DIR-859 1.05 and 1.06B01 Beta01 devices allow remote attackers to execute arbitrary OS commands via a urn: to the M-SEARCH method in ssdpcgi() in /htdocs/cgibin, because HTTP_ST is mishandled. The value of the urn: service/device is checked with the strstr function, which allows an attacker to concatenate arbitrary commands separated by shell metacharacters.

Los dispositivos D-Link DIR-859 versiones 1.05 y 1.06B01 Beta01, permiten a atacantes remotos ejecutar comandos arbitrarios del Sistema Operativo por medio de una urn: en el método M-SEARCH en la función ssdpcgi() en el archivo /htdocs/cgibin, porque HTTP_ST se maneja inapropiadamente. El valor de la urn: service/device es verificado con la función strstr, lo que permite a un atacante concatenar comandos arbitrarios separados por metacaracteres de shell.
