Title
Realtek rtl81xx SDK Wi-Fi Driver MgntActSet_TEREDO_SET_RS_PACKET Heap-based Buffer Overflow Local Privilege Escalation Vulnerability
Summary
Realtek rtl81xx SDK Wi-Fi Driver MgntActSet_TEREDO_SET_RS_PACKET Heap-based Buffer Overflow Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Realtek rtl81xx SDK Wi-Fi driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the MgntActSet_TEREDO_SET_RS_PACKET function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-25857.
