Summary

The stack-based buffer overflow vulnerability identified in the TP-Link Archer A54 routers arises from inadequate validation of user-supplied data length before it is copied to a fixed-length stack-based buffer in the libcmm.so file. This flaw can be exploited by network-adjacent attackers who, after successful authentication, can execute arbitrary code within the context of root. Protecting against this vulnerability requires immediate attention to ensure network security and prevent unauthorized access.
