AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
NETGEAR WAC510 devices before firmware 5.0.0.17 are vulnerable to vertical privilege escalation, allowing an unauthenticated adjacent attacker to gain elevated privileges.
Vulnerability
A vertical privilege escalation vulnerability exists in NETGEAR WAC510 devices running firmware versions prior to 5.0.0.17. The vulnerability allows an attacker to gain higher privileges on the device. The exact mechanism is not disclosed in the available references, but the affected component is likely the web interface or firmware update mechanism [1].
Exploitation
An attacker can exploit this vulnerability without authentication by being on the same adjacent network (CVSS 3.0 vector AV:A/AC:L/PR:N/UI:N/S:U). The attacker sends specially crafted packets or requests to the device to escalate privileges. No user interaction is required [1].
Impact
Successful exploitation results in a complete compromise of confidentiality, integrity, and availability (CVSS v3 score 7.8). The attacker gains administrative access to the device, allowing them to read sensitive data, modify configuration, or cause denial of service [1].
Mitigation
NETGEAR has released firmware version 5.0.0.17 to fix this vulnerability. Users should upgrade to this version or later immediately [1]. No workarounds are available.
