CVE-2022-27646 (GCVE-0-2022-27646)

Vulnerability from cvelistv5 – Published: 2023-03-29 00:00 – Updated: 2025-02-18 17:47
VLAI?
Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the circled daemon. A crafted circleinfo.txt file can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15879.
