CVE-2025-60689MED 5.4EPSS 18%
An unauthenticated command injection vulnerability exists in the Start_EPI function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The vulnerability occurs because user-supplied CGI parameters (wl_ant, wl_ssid, wl_rate, ttcp_num, ttcp_ip, ttcp_size) are concatenated into system command strings without proper sanitization and executed via wl_exec_cmd. Successful exploitation allows remote attackers to execute arbitrary commands on the device without authentication.
CVE-2025-60690HIGH 8.8Real · low riskEPSS 4%
A stack-based buffer overflow exists in the get_merge_ipaddr function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to four user-supplied CGI parameters matching <parameter>_0~3 into a fixed-size buffer (a2) without bounds checking. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication.
