info:
|
|
name: TBK DVR4104/DVR4216 Devices - Authentication Bypass
|
|
author: princechaddha
|
|
severity: critical
|
|
description: |
|
|
TBK DVR4104 and DVR4216 devices, as well as Novo, CeNova, QSee, Pulnix, XVR 5 in 1, Securus, Night OWL, DVR Login, HVR Login, and
|
|
MDVR Login, which run re-branded versions of the original TBK DVR4104 and DVR4216 series, allow remote attackers to bypass
|
|
authentication via a "Cookie: uid=admin" header, as demonstrated by a device.rsp?opt=user&cmd=list request that provides credentials within JSON data in a response.
|
|
remediation: |
|
|
Apply the latest firmware update provided by the vendor to fix the authentication bypass vulnerability and ensure strong and unique passwords are used for device access.
