Critical Security Vulnerabilities Discovered in Netcomm and TP-Link Routers

Security vulnerabilities have been disclosed in Netcomm and TP-Link routers, some of which could be weaponized to achieve remote code execution. The flaws, tracked as CVE-2022-4873 and CVE-2022-4874, concern a case of stack-based buffer overflow and authentication bypass and impact Netcomm router...

CVE-2022-4873

On Netcomm router models NF20MESH, NF20, and NL1902 a stack based buffer overflow affects the sessionKey parameter. By providing a specific number of bytes, the instruction pointer is able to be overwritten on the stack and crashes the application at a known location...
