CWE-119Published: February 6, 2026· Updated: Jun 17, 2026
Official Description
A vulnerability was detected in IP-COM W30AP up to 1.0.0.11(1340). Affected by this issue is the function R7WebsSecurityHandler of the file /goform/wx3auth of the component POST Request Handler. The manipulation of the argument data results in stack-based buffer overflow. The attack may be performed from remote. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Risk Analysis
IP-COM W30AP firmware is affected by a stack-based buffer overflow in its web request handler. This critical vulnerability allows remote attackers to execute arbitrary code or crash the device.
The exploit is public and available for use, but the vulnerability is not currently in the CISA KEV catalog. It is remotely exploitable with low attack complexity.
Apply the latest firmware updates from IP-COM. If an update is unavailable, restrict management access to the device to trusted internal networks only.
Technical Analysis
CVE-2026-2017 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
