CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Description
A stack-based buffer-overflow exists in Edimax IP-Camera IC-3116W (v3.06) and IC-3140W (v3.07), which allows an unauthenticated, unauthorized attacker to perform remote-code-execution due to a crafted GET-Request. The overflow occurs in binary ipcam_cgi due to a missing type check in function doGetSysteminfo(). This has been fixed in version: IC-3116W v3.08.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 2.3% probability of exploitation activity in the next 30 days.
