CVE-2025-15091
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 determined in UTT 进取 512W up to 1.7.7-171114. This issue affects the function strcpy of the file /goform/formPictureUrl. This manipulation of the argument importpictureurl causes buffer overflow. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.
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 confidenceBuffer overflow vulnerability in UTT 进取 512W router firmware. The strcpy function in /goform/formPictureUrl copies the importpictureurl parameter without bounds checking, allowing attackers to overwrite adjacent memory and potentially execute arbitrary code remotely.

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.
-
Identify the router modelCheck the device label, web interface login page, or SNMP/sysinfo for the model name 'UTT 进取 512W' or '512W'Affected if The device is not a UTT 512W router, then it is not affected by this specific CVE
-
Check the firmware versionLog into the router web interface and navigate to System Status or Firmware Upgrade page to view the current firmware version. Alternatively, check via telnet/SSH if enabled by running 'cat /proc/version' or checking /etc/versionAffected if The firmware version is greater than 1.7.7-171114 OR the version cannot be determined, then the device may still be vulnerable if the version is unknown or <= 1.7.7-171114
-
Verify the vulnerable web endpoint existsAttempt to access http://<router-ip>/goform/formPictureUrl - if the page loads or returns a response (even an error), the web interface and this endpoint are presentAffected if The endpoint returns any response, indicating the web interface is active and the vulnerable code path exists
-
Check network exposure of the management interfaceReview firewall rules, NAT configurations, or access lists to determine if the router's HTTP/HTTPS management port (typically 80/443) is accessible from untrusted networks such as the internet or guest VLANsAffected if The management interface is accessible from untrusted networks without proper access controls, then remote exploitation is possible
The device is affected if it is a UTT 进取 512W router running firmware version 1.7.7-171114 or lower AND the web management interface is accessible.

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.
From vendor dataApply vendor firmware patch when available; until then, disable or restrict access to the /goform/formPictureUrl web interface and place device behind a firewall to reduce attack surface.
