CVE-2026-6186: Buffer Overflow in UTT HiPER 1200GW
CVE-2026-6186 is a high-severity buffer overflow vulnerability in UTT HiPER 1200GW firmware version 2. 5. 3-170306. The flaw exists in the strcpy function within the /goform/formNatStaticMap file, where manipulation of the NatBind argument can cause a buffer overflow. This vulnerability can be exploited remotely without user interaction or privileges. Public exploit code has been disclosed, increasing the risk of exploitation. No official patch or remediation guidance has been provided by the vendor as of the publication date.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the strcpy function used in the /goform/formNatStaticMap endpoint of UTT HiPER 1200GW devices running firmware up to version 2.5.3-170306. An attacker can remotely manipulate the NatBind parameter to trigger the overflow, potentially leading to arbitrary code execution or denial of service. The CVSS v4.0 base score is 8.7, reflecting high impact and ease of exploitation without privileges or user interaction. Although public exploits exist, no vendor patch or official remediation has been documented yet.
Potential Impact
Successful exploitation of this vulnerability may allow remote attackers to execute arbitrary code or cause a denial of service on affected UTT HiPER 1200GW devices. The vulnerability requires no user interaction and can be triggered remotely, increasing its risk. The presence of public exploit code further elevates the threat level. However, there is no confirmed evidence of exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to restrict external access to the affected device's management interfaces, especially the /goform/formNatStaticMap endpoint, and monitor for unusual activity. Avoid exposing the device directly to untrusted networks. Follow vendor communications closely for updates on patches or official mitigations.
