According to the CVSS 4.0 vector the attacker must already hold valid credentials (PR:L), so the flaw is a post-authentication escalation/denial-of-service vector rather than an unauthenticated remote compromise. Publicly available exploit code exists (a GitHub PoC was published alongside the disclosure) and the report indicates the vendor was contacted but never responded, so no fixed firmware has been released; EPSS is only 0.11% (29th percentile), and the overall risk is low because exploitation requires an authenticated session and the affected device/firmware combination has a very small deployment base.

An unsafe strcpy() in the /goform/ConfigExceptMSN handler of UTT 进取 (JinQu) 512W router firmware up to and including 1.7.7-171114 lets an authenticated remote attacker overflow a stack buffer by supplying an overlong 'remark' parameter, corrupting adjacent memory and potentially leading to code execution in the context of the device's web server.

Publicly available exploit code exists (a GitHub write-up with a PoC under the cymiao1978/cve repository), so the barrier to reproduction is low, although no CISA KEV entry indicates confirmed active exploitation in the wild; real-world risk is dominated by whether the router's management interface is exposed beyond the trusted LAN.

The input's CVSS vector (PR:L, UI:N) confirms authentication is required but that no user interaction is needed once a session exists, and publicly available exploit code exists - no CISA KEV entry indicates confirmed active exploitation at the time of analysis. With a CVSS 4.0 base score of 7.4 and high confidentiality, integrity, and availability impact on the device, this is a genuine but moderate-priority issue rather than a top-tier emergency, primarily limited by the authentication prerequisite, the requirement that the admin interface be reachable, and the narrow deployment base of this specific router model.

A buffer overflow in the UTT 518G router firmware (up to V3v3.2.7-210919-161313) is reachable through the authenticated web management endpoint /goform/formTaskEdit_ap, where an oversized txtMin2 argument overwrites memory and can lead to high-integrity/high-availability impact on the device, with the assessed CVSS 3.1 base score of 8.8 and the vendor-published CVSS 4.0 score of 7.4. The CVSS 4.0/3.1 vectors both carry PR:L, meaning the attacker must already hold at least low-level credentials on the router, so the practical exposure is limited to users who can log in to the web console rather than any remote unauthenticated party on the internet. Publicly available exploit code exists (linked from a GitHub PoC write-up), but there is no CISA KEV listing and EPSS is only 0.84% (56th percentile), so signals are mixed and this is a real but limited-priority issue.

An authenticated buffer overflow in the UTT 1250GW gateway firmware (all builds through v2v3.2.2-200710) lets an attacker with a low-privilege session on the device's web management interface send an oversized pvid parameter to /goform/aspChangeChannel, corrupting memory on the stack via an unchecked strcpy and potentially achieving full code execution on the gateway. Exploitation is remote and low-complexity with no user interaction, but is gated by the need for prior authentication (CVSS PR:L), which is the main limiting factor. Publicly available exploit code exists on GitHub, and although the vendor was contacted early, no response or fixed firmware version has been published.

Publicly available exploit code exists (a GitHub write-up with a PoC under the cymiao1978/cve repository), so the barrier to reproduction is low, although no CISA KEV entry indicates confirmed active exploitation in the wild; real-world risk is dominated by whether the router's management interface is exposed beyond the trusted LAN.

A stack-based buffer overflow in the web management component of UTT 进取 512W router firmware (versions up to and including 1.7.7-171114) lets an attacker who holds a valid low-privilege management session crash or potentially execute code on the device by submitting an oversized 'timestart' value to /goform/formConfigNoticeConfig, which is copied with the unbounded strcpy function.

With a CVSS 4.0 base score of 7.4 and high confidentiality, integrity, and availability impact on the device, this is a genuine but moderate-priority issue rather than a top-tier emergency, primarily limited by the authentication prerequisite, the requirement that the admin interface be reachable, and the narrow deployment base of this specific router model.
