Summary

CVE-2026-7418 is a high-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability. Its CVSS base score is 7.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Process Injection (T1055); ranked at the 45th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-7418 is a buffer overflow vulnerability in the UTT HiPER 1250GW router firmware versions up to 3.2.7-210907-180535. The issue resides in the strcpy function within the route/goform/NTP file, where manipulation of the Profile argument triggers the overflow. Published on 2026-04-29, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).

Remote attackers with low privileges, such as authenticated users, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation leads to high-impact consequences, including unauthorized disclosure of sensitive information, modification of data or system configuration, and denial of service through complete loss of availability.

Advisories from VulDB (vuln/360155) and a related GitHub repository detail the vulnerability and publicly disclose a working exploit, emphasizing remote exploitability. No specific patches or vendor mitigations are referenced in the available sources; practitioners should isolate affected devices, monitor for exploitation attempts targeting the NTP form endpoint, and pursue firmware updates from UTT if available.

The exploit's public disclosure heightens the risk of real-world attacks against exposed UTT HiPER 1250GW instances.
