Description
A stack-based buffer overflow vulnerability exists in the libshared.so library of Cisco Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The functions get_mac_from_ip and get_ip_from_mac use sscanf with overly permissive "%100s" format specifiers to parse entries from /proc/net/arp into fixed-size buffers (v6: 50 bytes, v7 sub-arrays: 50 bytes). This allows local attackers controlling the contents of /proc/net/arp to overflow stack buffers, leading to memory corruption, denial of service, or potential arbitrary code execution.

Executive Summary

This vulnerability is a stack-based buffer overflow in the libshared.so library of Cisco Linksys E1200 v2 routers. Specifically, the functions get_mac_from_ip and get_ip_from_mac use sscanf with overly permissive format specifiers to parse entries from /proc/net/arp into fixed-size buffers. Because the input can be controlled locally, an attacker can overflow these buffers, causing memory corruption, denial of service, or potentially arbitrary code execution.

Impact Analysis

If exploited, this vulnerability can lead to memory corruption, denial of service (crashing the device), or even allow an attacker to execute arbitrary code on the affected router. This could compromise the security and availability of the device and the network it supports.
