CVE-2017-3184: Acti Camera Firmware: Hard-coded credentials or backdoor

CVE-2017-3184 is rated critical with a CVSS v3.0 base score of 9.8 and NVD lists Acti Camera Firmware as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

ACTi cameras including the D, B, I, and E series using firmware version A1D-500-V6.11.31-AC fail to properly restrict access to the factory reset page. An unauthenticated, remote attacker can exploit this vulnerability by directly accessing the http://x.x.x.x/setup/setup_maintain_firmware-default.html page. This will allow an attacker to perform a factory reset on the device, leading to a denial of service condition or the ability to make use of default credentials (CVE-2017-3186).

Severity breakdown

CVSS v3.0 9.8: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
