Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A stack-based buffer overflow vulnerability, tracked as CVE-2025-60690 and associated with CWE-121, affects the httpd binary on Linksys E1200 v2 routers running firmware version E1200_v2.0.11.001_us.tar.gz. The issue resides in the get_merge_ipaddr function, which concatenates up to four user-supplied CGI parameters matching the pattern <parameter>_0 through <parameter>_3 into a fixed-size buffer named a2 without performing bounds checking. This flaw has a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.
Remote attackers on an adjacent network can exploit this vulnerability by sending specially crafted HTTP requests to the affected router, requiring no authentication or user interaction. Successful exploitation allows arbitrary code execution or denial of service, such as crashing the httpd process, enabling attackers to potentially compromise the device, pivot to other network assets, or disrupt connectivity.
