Who should care

Defenders responsible for UTT HiPER 1250GW devices, especially those with versions up to 3.2.7-210907-180535, should assess exposure and prioritize verification and potential remediation.

Why it matters

CVE-2026-78169 is a stack-based buffer overflow vulnerability in UTT HiPER 1250GW devices that allows remote attackers to exploit the device. Defenders should prioritize verifying exposure and assessing the network for potential remote exploitation attempts.

• Remote exploitation of the vulnerability could lead to device compromise.
• Successful exploitation could result in arbitrary code execution.
• Defenders should verify exposure and assess the network for potential remote exploitation attempts.
• Remediation priority is high due to the potential for remote exploitation and device compromise.

Technical summary

The vulnerability is caused by a stack-based buffer overflow in the strcpy function of the /goform/aspRemoteApConfTempSend file in the HTTP Request Handler component. This can be exploited remotely by manipulating the Profile argument, potentially leading to device compromise and arbitrary code execution. The vulnerability has a CVSS score of 8.6 and is considered HIGH severity. Defenders should prioritize verifying exposure of UTT HiPER 1250GW devices, especially those with versions up to 3.2.7-210907-180535, and assess the network for potential remote exploitation attempts.

Defensive priority

Defenders should prioritize verifying exposure of UTT HiPER 1250GW devices, especially those with versions up to 3.2.7-210907-180535, and assess the network for potential remote exploitation attempts.
