CVE-2022-27646 – NETGEAR R6700v3 circled Stack-based Buffer Overflow Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2022-27646

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. • https://kb.netgear.com/000064721/Security-Advisory-for-Multiple-Vulnerabilities-on-Multiple-Products-PSV-2021-0324 https://www.zerodayinitiative.com/advisories/ZDI-22-523 • CWE-121: Stack-based Buffer Overflow •

CVE-2022-27644 – NETGEAR R6700v3 Improper Certificate Validation Vulnerability

https://notcve.org/view.php?id=CVE-2022-27644

This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloading of files via HTTPS. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. • https://kb.netgear.com/000064721/Security-Advisory-for-Multiple-Vulnerabilities-on-Multiple-Products-PSV-2021-0324 https://www.zerodayinitiative.com/advisories/ZDI-22-520 • CWE-295: Improper Certificate Validation •
