The UTT HiPER 810G router firmware version 1.7.7-171114 contains a critical buffer overflow vulnerability in the strcpy function within the /goform/formPolicyRouteConf file. This vulnerability stems from improper input validation where the GroupName parameter is directly copied into a fixed-size buffer without adequate bounds checking, creating an exploitable condition that can be remotely triggered through web interface interactions.
This specific flaw represents a classic stack-based buffer overflow vulnerability categorized under CWE-121, where insufficient boundary checking allows arbitrary data to overwrite adjacent memory locations. The affected device operates with a web-based management interface that processes user inputs through the formPolicyRouteConf endpoint, making it susceptible to remote code execution when attackers manipulate the GroupName parameter to exceed allocated buffer boundaries. The vulnerability has been publicly disclosed and actively exploited in the wild, indicating that threat actors have developed working exploits for this particular weakness.
The operational impact of this vulnerability extends beyond simple denial of service scenarios as it enables remote code execution capabilities that could allow attackers to fully compromise the affected router. Once exploited, adversaries could gain persistent access to the device, potentially using it as a pivot point for further network reconnaissance and lateral movement attacks against connected systems. The router's role as a network gateway makes this particularly dangerous as it provides attackers with potential access to internal network resources that would otherwise be protected by firewall rules.
Mitigation strategies should prioritize immediate firmware updates from UTT to address the buffer overflow condition, while implementing network segmentation measures to limit potential attack surface. Network administrators should also deploy intrusion detection systems capable of identifying exploitation attempts targeting this specific vulnerability and consider disabling unnecessary web management interfaces. The ATT&CK framework categorizes this type of vulnerability under T1059 for remote code execution and T1071 for application layer protocols, highlighting the need for comprehensive defensive measures including network monitoring, access control restrictions, and regular security assessments to prevent exploitation of similar buffer overflow conditions in other network infrastructure components.
