Detailsinfo

A vulnerability was found in Uniview IPC_G6103, IPC_G61, IPC21, IPC23, IPC32, IPC36, IPC62 and IPC_HCMN. It has been classified as critical. This affects some unknown processing of the component Service Port 7788. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple models of the Uniview IP Camera (e.g., IPC_G6103 B6103.16.10.B25.201218, IPC_G61, IPC21, IPC23, IPC32, IPC36, IPC62, and IPC_HCMN) offer an undocumented UDP service on port 7788 that allows a remote unauthenticated attacker to overflow an internal buffer and achieve code execution. By using this buffer overflow, a remote attacker can start the telnetd service. This service has a hardcoded default username and password (root/123456). Although it has a restrictive shell, this can be easily bypassed via the built-in ECHO shell command.

The weakness was disclosed 06/01/2023. The advisory is shared at ssd-disclosure.com. This vulnerability is uniquely identified as CVE-2021-45039 since 12/13/2021.
