CVE-2020-10883 (GCVE-0-2020-10883)

Vulnerability from cvelistv5 – Published: 2020-03-25 19:15 – Updated: 2024-08-04 11:14

Summary

This vulnerability allows local attackers to escalate privileges on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the file system. The issue lies in the lack of proper permissions set on the file system. An attacker can leverage this vulnerability to escalate privileges. Was ZDI-CAN-9651.
