Name of the Vulnerable Software and Affected Versions UTT HiPER 1200GW versions prior to 2.5.3-170306

Description A stack-based buffer overflow exists in the Web Management Interface component. A remote attacker can trigger this issue by manipulating arguments related to the PPTP server address, username, password, or tunnel name within an unknown function of the '/goform/formPptpClientConfig' endpoint. A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations Update to a version later than 2.5.3-170306. As a temporary workaround, restrict access to the '/goform/formPptpClientConfig' endpoint to minimize the risk of exploitation.
