Summary
A stack-based buffer overflow vulnerability exists in UTT HiPER 1200GW up to 2.5.3-170306 in the strcpy function of /goform/pptpSrvGlobalConfig. Manipulating the EncryptionMode argument allows remote code execution. The exploit is public, and the vendor did not respond.
Risk Assessment
A remote attacker can crash the device or execute arbitrary code, potentially leading to full control of the router and network.
Recommendation
Contact the vendor for patches. Restrict device access and monitor network traffic.
