Lifecycle Timeline
3Description
A stack-based buffer overflow vulnerability exists in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032). The function sub_4045A8 reads up to 256 bytes from /sys/class/net/%s/address into a local buffer and then copies it into caller-provided buffer a1 using strcpy without boundary checks. Since a1 is often allocated with significantly smaller sizes (20-32 bytes), local attackers controlling the contents of /sys/class/net/%s/address can trigger buffer overflows, leading to memory corruption, denial of service, or potential arbitrary code execution.
Analysis
A stack-based buffer overflow vulnerability exists in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032). Rated medium severity (CVSS 5.9), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical Context
This vulnerability is classified under CWE-121. A stack-based buffer overflow vulnerability exists in the mtk_dut binary of Linksys E7350 routers (Firmware 1.1.00.032).
