Deeper analysis

CVE-2024-0778 is an OS command injection vulnerability, tracked as CWE-78, that affects the setNatConfig function in the file /Interface/DevManage/VM.php of Uniview ISC 2500-S appliances up to version 20210930. The flaw arises from unsanitized handling of the natAddress, natPort, and natServerPort arguments and was assigned a CVSS 3.1 score of 8.0. The product is explicitly unsupported and end-of-life.

An attacker with adjacent-network access and low privileges can supply crafted values to these parameters and execute arbitrary operating-system commands on the device, resulting in full compromise of confidentiality, integrity, and availability.

Vendor contact confirmed that the product is no longer maintained and should be retired and replaced; no patches or mitigations are provided.

Public exploit code has been released. The EPSS score rose materially from lower values after disclosure to a peak of 0.6118 on 2025-12-11 before receding to the current 0.4972.
