CVE-2024-57543 Details
Description
Linksys E8450 v1.2.00.360516 was discovered to contain a buffer overflow vulnerability. The parsed field (dhcpstart_ip) is copied to the stack without length verification.
A buffer overflow vulnerability has been identified in the Linksys E8450 router, specifically in version 1.2.00.360516. The issue arises in the JSON parsing function 'sub_422eb8', where the 'dhcpstart_ip' field is copied to the stack using 'strcpy' without proper length validation. This lack of verification creates an opportunity for a buffer overflow, potentially allowing for arbitrary code execution or causing the device to crash.
