Name of the Vulnerable Software and Affected Versions TP-Link Archer AX53 versions 1.0 through 1.3.1 Build 20241120

Description A heap-based buffer overflow exists in the tmpserver modules of TP-Link Archer AX53. This flaw allows authenticated attackers in an adjacent network to trigger a segmentation fault or potentially execute arbitrary code. The issue stems from insufficient validation of a packet field, specifically its offset, which dictates the write location in memory. By manipulating this offset within a crafted packet, an attacker can redirect writes to arbitrary memory locations.

Recommendations Update TP-Link Archer AX53 to a version later than 1.3.1 Build 20241120.
