VAR-202303-2602

Vulnerability from variot - Updated: 2025-08-09 23:13

The specific flaw exists within the parsing of firmware images. 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. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19703. TP-LINK Technologies of archer ax21 A stack-based buffer overflow vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state

CVE-2023-27346 (GCVE-0-2023-27346)

Vulnerability from cvelistv5 – Published: 2024-05-03 01:56 – Updated: 2024-09-18 18:28

Title

TP-Link AX1800 Firmware Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

Summary

TP-Link AX1800 Firmware Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link AX1800 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of firmware images. 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. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-19703.

Severity ?

8.8 (High)
