What is CVE-2023-27346?

A vulnerability in the TP-Link AX1800 router firmware allows network-adjacent attackers to exploit a stack-based buffer overflow condition. This exploitation is made possible due to inadequate validation of user-supplied data length during firmware image parsing, which can lead to arbitrary code execution with root privileges. No authentication is necessary to carry out this attack, underscoring the critical need for users to ensure their devices are updated with the latest firmware to mitigate potential risks. For detailed technical insights, refer to ZDI-23-377.
