CVE-2026-11814: CWE-295 Improper certificate validation in NETGEAR BE9300
CVE-2026-11814 is a medium severity vulnerability affecting the NETGEAR BE9300 device. It involves improper certificate validation (CWE-295) that enables a network-adjacent attacker capable of intercepting and modifying local network traffic to perform command injection. This vulnerability compromises the confidentiality and integrity of the affected device. The issue is limited to certain region-specific SKUs. No patch or official remediation guidance is currently available.
AI Analysis
Technical Summary
This vulnerability in NETGEAR BE9300 devices arises from improper certificate validation, classified under CWE-295. It allows a network-adjacent attacker with man-in-the-middle capabilities to inject commands by intercepting and modifying local network traffic. The flaw affects specific region-restricted SKUs of the BE9300 model. The CVSS 4.0 base score is 4.9, indicating medium severity, with attack vector local network (AV:A), high attack complexity (AC:H), and partial impact on confidentiality and integrity. No known exploits are reported in the wild, and no vendor remediation or patch has been disclosed as of the publication date.
Potential Impact
An attacker positioned on the local network who can intercept and alter traffic may exploit this vulnerability to execute commands on the affected device, leading to compromise of confidentiality and integrity. The impact is limited to certain region-specific SKUs of the NETGEAR BE9300. There is no indication of availability impact or privilege escalation. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, network administrators should limit exposure of affected devices to untrusted local networks and monitor for suspicious network activity consistent with man-in-the-middle attacks. No official remediation or temporary fix is currently documented.
