Execution
Trigger strcpy buffer overflow
Impact
Execute arbitrary code with device privileges

Vulnerability AssessmentAI

Exploitation Requires authenticated login (PR:L) to UTT HiPER 1200GW running firmware versions up to 2.5.3-170306. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS v3.1 score of 8.8 (High) reflects significant impact with network-based attack vector (AV:N), low complexity (AC:L), and requiring only low privileges (PR:L) with no user interaction (UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained or brute-forced low-privilege credentials to the router's web interface (possibly through credential stuffing or default passwords) sends a crafted HTTP request to the /goform/websHostFilter endpoint with an oversized input parameter. The strcpy function copies this malicious payload into a fixed-size stack buffer without bounds checking, overwriting adjacent memory including the return address. …
Remediation Contact UTT Technologies to inquire about firmware updates newer than version 2.5.3-170306, as the CVSS temporal vector indicates no confirmed remediation level (RL:X), suggesting a patch may not be officially available. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify and inventory all UTT HiPER 1200GW routers in your environment, particularly those running firmware versions up to 2.5.3-170306, and isolate affected devices from critical network segments if operationally feasible. …
