Remote Buffer Overflow in UTT 进取 520W /goform/formPictureUrl
CVE-2026-0841 is a high-severity remote buffer overflow vulnerability affecting UTT 进取 520W firmware version 1.7.7-180627. The flaw is in the /goform/formPictureUrl handler, where the importpictureurl argument is copied with strcpy without proper bounds checking. An attacker able to reach the affected web management interface can supply crafted input that overflows the destination buffer, causing memory corruption. Public reporting indicates the issue is remotely exploitable and that exploit details are publicly available. The vendor reportedly did not respond to early disclosure attempts.
