Description

TP-Link Archer A54 libcmm.so dm_fillObjByStr Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer A54 routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the file libcmm.so. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
