CVE-2026-0841
HighSummary
A vulnerability was detected in UTT 进取 520W version 1.7.7-180627. The issue affects the strcpy function in the file /goform/formPictureUrl, where manipulation of the importpictureurl argument leads to buffer overflow. The attack can be launched remotely, and the exploit is now public.
Risk Assessment
The organization is exposed to remote takeover or denial of service of the device, which may disrupt network operations or compromise data integrity. The public exploit increases the risk of active exploitation.
Recommendation
Immediately check if the device is affected and, if possible, disconnect it from the network or apply available updates. If no updates are available, restrict access to the administrative panel and monitor network traffic.
