Remote buffer overflow in UTT HiPER 1200GW routers (firmware up to 2.5.3-170306) allows network-reachable authenticated attackers to corrupt memory by supplying an oversized SSID value to the /goform/formConfigFastDirectionW endpoint, which calls strcpy without bounds checking on user input. Full confidentiality, integrity, and availability impact on the device is possible, potentially enabling arbitrary code execution and pivoting into the network behind the gateway. A public proof-of-concept exploit is available on GitHub; no active exploitation has been confirmed in CISA KEV at time of analysis.
Stack-based buffer overflow in UTT HiPER 1200GW firmware through version 2.5.3-170306 enables remote code execution via a crafted timestart parameter submitted to the /goform/formGroupConfig endpoint. The root cause is an unbounded strcpy() call (CWE-121) in the formGroupConfig handler that overwrites stack memory without validating input length. A public proof-of-concept exploit has been published to GitHub, and the CVSS 4.0 score of 8.6 with high impact across both the vulnerable device and subsequent network systems underscores the potential for network-wide compromise through this gateway appliance.
Stack-based buffer overflow in UTT HiPER 1200GW firmware (versions up to 2.5.3-170306) enables authenticated remote attackers to corrupt stack memory via the EncryptionMode parameter in the PPTP VPN configuration endpoint, potentially achieving arbitrary code execution on the device. The root cause is unsafe use of strcpy() without bounds validation in the /goform/pptpSrvGlobalConfig handler. A public proof-of-concept exploit has been disclosed on GitHub; the vendor did not respond to coordinated disclosure, leaving no official patch available at time of analysis. No public exploit identified at time of analysis as KEV, but POC lowers the practical exploitation barrier significantly.
Stack-based buffer overflow in UTT HiPER 1200GW firmware up to v2.5.3-170306 enables network-reachable authenticated attackers to corrupt stack memory and achieve arbitrary code execution on the device. The vulnerable C runtime function strcpy in the web management endpoint /goform/ConfigAdvideo performs no bounds validation on the timestart HTTP parameter, allowing oversized input to overwrite return addresses and redirect execution flow. A public proof-of-concept exploit is available on GitHub; no vendor patch exists as UTT did not respond to the coordinated disclosure.
Stack-based buffer overflow in UTT HiPER 1200GW routers (firmware up to 2.5.3-170306) allows authenticated remote attackers to corrupt memory via the Profile parameter in the /goform/formFireWall endpoint, where unsafe strcpy usage processes the input. Publicly available exploit code exists, increasing the realistic risk of attempted compromise against exposed management interfaces. No CISA KEV listing has been published, so exploitation is not yet confirmed active in the wild.
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. No KEV listing or EPSS data is provided in the input, so widespread automated exploitation has not been confirmed.
Buffer overflow in UTT HiPER 1200GW router versions up to 2.5.3-170306 enables remote authenticated attackers to execute arbitrary code with high privileges via malformed NatBind parameters to the /goform/formNatStaticMap endpoint. Publicly available exploit code exists (GitHub POC published), significantly lowering exploitation barrier. EPSS data not available, but combination of network attack vector, low complexity (CVSS AC:L), and public POC indicates elevated real-world exploitation risk for internet-facing devices with weak credential protection.
Unauthenticated attackers can trigger a buffer overflow in UTT HiPER 1200GW firmware versions up to 2.5.3-170306 via the /goform/websHostFilter endpoint, enabling remote code execution with full system compromise. Public exploit code is available and there is currently no patch, leaving affected devices at immediate risk. The vulnerability requires only network access and valid credentials to exploit, making it readily actionable for threat actors.
