Vulnerability from github – Published: 2023-11-09 00:33 – Updated: 2023-11-09 00:33

Details

Zavio CF7500, CF7300, CF7201, CF7501, CB3211, CB3212, CB5220, CB6231, B8520, B8220, and CD321

IP Cameras

with firmware version M2.1.6.05 are vulnerable to multiple instances of stack-based overflows. During the processing and parsing of certain fields in XML elements from incoming network requests, the product does not sufficiently check or validate allocated buffer size. This may lead to remote code execution.

Severity ?

9.8 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
