VAR-201904-0689
Vulnerability from variot - Updated: 2024-11-23 21:52An issue was discovered on Tenda AC7 devices with firmware through V15.03.06.44_CN(AC7), AC9 devices with firmware through V15.03.05.19(6318)_CN(AC9), and AC10 devices with firmware through V15.03.06.23_CN(AC10). A buffer overflow vulnerability exists in the router's web server (httpd). When processing the page parameters for a post request, the value is directly written with sprintf to a local variable placed on the stack, which overrides the return address of the function, a causing buffer overflow. Tenda AC7 , AC9 , AC10 The firmware contains a buffer error vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Tenda AC7 and others are all wireless routers from China's Tenda. This vulnerability originates from a network system or product that incorrectly validates data boundaries when performing operations on memory, causing incorrect read and write operations to be associated with other memory locations
