NETGEAR RAXE CVE-2026-62656

Exploitation requires two concrete prerequisites: the attacker must be authenticated to the router with at least user-level credentials (PR:H per CVSS 4.0 vector), and must have network adjacency to the router's management interface (AV:A - same LAN, WLAN, or directly connected segment). No special non-default router configuration is required beyond the attacker possessing valid credentials. Limiting factors include the requirement for prior authentication, which restricts the attack to insiders, credential-compromise scenarios, or users already connected to the home or office network segment. Internet-facing exploitation is not possible given AV:A. The SSVC rating of automatable: no further confirms this cannot be reliably chained into worm-style or mass-exploitation campaigns.

The CVSS 4.0 score of 5.4 (Medium) reflects a constrained attack surface: AV:A requires adjacency to the router's management network, and PR:H requires the attacker to already hold valid credentials. The integrity-only impact (VI:H, no confidentiality or availability impact) further limits blast radius. The EPSS score of 0.15% at the 5th percentile is extremely low, consistent with SSVC indicating exploitation: none and automatable: no - meaning this is unlikely to be mass-exploited in automated campaigns. The E:P modifier in the provided CVSS 4.0 vector indicates a proof-of-concept exists, which elevates theoretical risk but has not translated to observed exploitation per KEV. The 'Authentication Bypass' tag in the intelligence data appears to describe post-authentication authorization bypass rather than authentication bypass in the strict sense, which is consistent with PR:H in the CVSS vector - this distinction matters for defenders assessing exposure. Overall, this is a realistic threat only from malicious insiders, compromised credential holders, or attackers already present on the LAN/WLAN segment, not a remotely exploitable mass-risk scenario.

An attacker who holds valid router credentials - either a legitimate user account or credentials obtained through phishing or credential stuffing - connects to the router's management interface while on the same adjacent network segment. They send a specially crafted request (e.g., a malformed API call or web interface parameter) that the firmware fails to validate, triggering execution of unauthorized commands such as altering firewall rules, DNS settings, or enabling remote access features. A proof-of-concept exists per the E:P CVSS 4.0 modifier, lowering the technical bar for this exploitation.
