Technical ContextAI · show details

This vulnerability is classified under CWE-121. 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. Affected products include: Linksys Re7000 Firmware. Version information: up to 16.

Executive ViewAI

Why It Matters

CVE-2025-60696 presents notable security risk, a stack-based buffer overflow vulnerability rated CVSS 8.4. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
