Lifecycle Timeline
5DescriptionCVE.org
A vulnerability was detected in UTT HiPER 1200GW up to 2.5.3-170306. This affects the function strcpy of the file /goform/formTaskEdit. The manipulation results in stack-based buffer overflow. The attack may be launched remotely. The exploit is now public and may be used.
AnalysisAI
Stack-based buffer overflow in UTT HiPER 1200GW routers (firmware versions up to 2.5.3-170306) allows remote authenticated attackers to corrupt memory via the strcpy function in the /goform/formTaskEdit endpoint. Publicly available exploit code exists, raising the practical risk despite the requirement for low-level privileges. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the UTT HiPER 1200GW HTTP management interface and valid low-privilege authenticated access to the device's web admin panel (CVSS PR:L), specifically the ability to invoke the /goform/formTaskEdit endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H) scores 7.4 (High), reflecting network-reachable, low-complexity attack with no user interaction but requiring low privileges (PR:L), meaning at least basic authenticated access to the management interface is needed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained low-privilege credentials to the UTT HiPER 1200GW web interface (e.g., via credential reuse, phishing, or default passwords) sends a crafted HTTP POST request to /goform/formTaskEdit containing an over-length parameter that is processed by the vulnerable strcpy call. The overflow overwrites saved return data on the stack, enabling either a denial of service of the router or execution of attacker-controlled shellcode on the embedded device, granting persistent control of the network gateway. … |
| Remediation | No vendor-released patch identified at time of analysis - UTT has not published a fixed firmware version in the available references. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Identify all UTT HiPER 1200GW routers in production and document firmware versions; immediately restrict administrative access to router management interfaces (particularly /goform/formTaskEdit endpoint) via firewall rules. …
