CVE-2026-2017
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStack-based buffer overflow in the R7WebsSecurityHandler function of the wx3auth POST request handler in IP-COM W30AP wireless access points (firmware up to 1.0.0.11). Remote attackers can overflow a stack buffer via the 'data' parameter in POST requests.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device model is W30APAccess the device web management interface or check the physical device label to verify the model number is IP-COM W30APAffected if Device model is not W30AP - this CVE does not apply
-
Check firmware versionLog into the web interface and navigate to the status or system information page to view the firmware version, or use the command line if accessible (e.g., 'cat /proc/version' or vendor-specific command)Affected if Firmware version is 1.0.0.11 or lower (the vulnerable version range)
-
Verify web management interface is accessibleAttempt to reach the device IP on HTTP/HTTPS ports (typically 80/443) to confirm the web interface is exposedAffected if Web interface is accessible externally or on untrusted networks - the attack vector requires sending POST requests to the wx3auth handler
-
Check if wx3auth endpoint existsSend a POST request to the wx3auth endpoint (typically /wx3auth or similar path) using a tool like curl to verify the handler exists: curl -X POST http://<device-ip>/wx3auth -d 'data=test'Affected if The wx3auth POST handler is present and responds - this confirms the vulnerable component is enabled
-
Confirm data parameter processingSend a POST request with a data parameter to the wx3auth handler and observe the response to confirm the parameter is processed by R7WebsSecurityHandlerAffected if The device accepts and processes the 'data' parameter through the wx3auth handler - this is the specific attack surface for the buffer overflow
You are affected if you have an IP-COM W30AP device running firmware version 1.0.0.11 or lower, and the web management interface with the wx3auth POST handler is accessible to untrusted networks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedSince the vendor did not respond to early disclosure and no patch is available, implement network segmentation to isolate affected devices, restrict access to the web management interface via firewall rules, and monitor for signs of exploitation.
- 1. Isolate the affected W30AP device on a restricted network segment to limit exposure to remote attacks.
- 2. Implement network-level filtering or firewall rules to block unauthorized access to the /goform/wx3auth endpoint from untrusted sources.
- 3. If possible, disable the vulnerable wx3auth function through the device's administrative interface if such an option exists.
- 4. Monitor vendor websites (IP-COM official support pages, gitee.com) for any future firmware updates addressing this vulnerability.
- 5. Consider replacing the W30AP with an alternative access point from a vendor that provides regular security updates.
- 6. If the device cannot be replaced, implement strict access control lists (ACLs) to ensure only trusted management IPs can reach the device's web interface.
