CVE-2026-18897: Stack-based Buffer Overflow in UTT HiPER 1250GW
CVE-2026-18897 is a high-severity stack-based buffer overflow vulnerability in the UTT HiPER 1250GW device, specifically in the strcpy function within /goform/getOneApConfTempEntry. The vulnerability is triggered by manipulating the tempName argument and can be exploited remotely without user interaction. The affected version is exactly 3.2.7-210907-180535. Although an exploit is publicly available, there is no vendor response or official patch at this time.
AI Analysis
Technical Summary
This vulnerability involves a stack-based buffer overflow caused by improper handling of the tempName argument in the strcpy function of the /goform/getOneApConfTempEntry file in UTT HiPER 1250GW firmware version 3.2.7-210907-180535. Remote attackers can exploit this flaw to potentially execute arbitrary code or cause a denial of service. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity. The vendor has not provided any response or remediation, and no official patch is currently available. Public exploit code exists, increasing the risk of exploitation.
Potential Impact
Successful exploitation of this vulnerability can lead to remote code execution or denial of service on the affected device. Given the high CVSS score and the availability of public exploit code, this poses a significant risk to affected systems. The lack of vendor response or patch increases exposure.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the absence of an official fix, users should consider mitigating exposure by restricting network access to the affected device, disabling vulnerable services if possible, and monitoring for suspicious activity related to this vulnerability.
