Vulnerability from variot
Grandstream GAC2500 1.0.3.35, GXP2200 1.0.3.27, GVC3202 1.0.3.51, GXV3275 before 1.0.3.219 Beta, and GXV3240 before 1.0.3.219 Beta devices allow unauthenticated remote code execution via shell metacharacters in a /manager?action=getlogcat priority field, in conjunction with a buffer overflow (via the phonecookie cookie) to overwrite a data structure and consequently bypass authentication. This can be exploited remotely or via CSRF because the cookie can be placed in an Accept HTTP header in an XMLHttpRequest call to lighttpd. plural Grandstream The product contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Grandstream GAC2500, etc. are all products of the American trend network (Grandstream). Grandstream GAC2500 is a business conference phone device based on Android platform. Grandstream GXP2200 is an IP phone. Grandstream GVC3202 is a full HD video conferencing device. A buffer error vulnerability exists in several Grandstream products. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc. The following products and versions are affected: Grandstream GAC2500 version 1.0.3.35; GXP2200 version 1.0.3.27; GVC3202 version 1.0.3.51; GXV3275 version before 1.0.3.219 Beta; GXV3240 version before 1.0.3.219 Beta
