CVE-2025-60696: n/a
A stack-based buffer overflow vulnerability exists in the makeRequest.cgi binary of Linksys RE7000 routers (Firmware FW_v2.0.15_211230_1012). The arplookup function parses lines from /proc/net/arp using sscanf("%16s ... %18s ..."), storing results into buffers v6 (12 bytes) and v7 (20 bytes). Since the format specifiers allow up to 16 and 18 bytes respectively, oversized input can overflow the buffers, resulting in stack corruption. Local attackers controlling /proc/net/arp contents can exploit this issue to cause denial of service or potentially execute arbitrary code.
AI Analysis
Technical Summary
CVE-2025-60696 is a stack-based buffer overflow vulnerability in the makeRequest.cgi binary of Linksys RE7000 routers running firmware FW_v2.0.15_211230_1012. The arplookup function uses sscanf with format specifiers "%16s" and "%18s" to parse lines from /proc/net/arp, storing the results into buffers of 12 and 20 bytes respectively. This mismatch allows oversized input to overflow these buffers, causing stack corruption. Exploitation requires local attacker control over /proc/net/arp contents, potentially leading to denial of service or arbitrary code execution.
Potential Impact
Successful exploitation can result in high impact including complete confidentiality, integrity, and availability compromise of the affected device. Specifically, attackers with local access controlling /proc/net/arp can trigger stack corruption, leading to denial of service or arbitrary code execution on the router.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to the device and limit the ability to modify /proc/net/arp contents to trusted users only.
