CRITICAL 9.8

DescriptionCVE.org

A flaw has been found in UTT HiPER 810 1.7.4-141218. The impacted element is the function strcpy of the file /goform/setSysAdm. This manipulation of the argument passwd1 causes buffer overflow. Remote exploitation of the attack is possible. The exploit has been published and may be used.

AnalysisAI

UTT HiPER 810 router firmware 1.7.4 has a stack buffer overflow in the /goform/setNat endpoint's strcpy function, enabling remote attackers to execute arbitrary code.

Technical ContextAI

The setNat handler in UTT HiPER 810 firmware 1.7.4 uses strcpy without bounds checking (CWE-119) to copy user-supplied input, causing a classic stack buffer overflow that overwrites the return address.
