Deeper analysis

CVE-2025-41275 is an OS command injection vulnerability (CWE-78) in the Console WebUI of Waterfall WF-500 TX and RX Hosts running version 7.9.1.0 R2502171040. The flaw allows improper neutralization of special elements in operating system commands, enabling execution of arbitrary commands on the underlying device.

Remote unauthenticated attackers can exploit the issue over the network without any user interaction or credentials, achieving full control over the host operating system and resulting in high impact to confidentiality, integrity, and availability.

The vulnerability was identified by Nozomi Networks Labs, with further details and mitigation guidance available in their advisory at https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-41275.

EPSS scores reached a peak of 0.0102 after disclosure before settling at the current value of 0.0037, indicating modest post-publication interest in the issue.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and neutralization of untrusted input to the WebUI to block OS command metacharacters.

AC-3 Access Enforcement good match
prevent

Enforces authentication and authorization checks before any WebUI request can reach command-execution paths.

SC-7 Boundary Protection partial match
prevent

Restricts network exposure of the Console WebUI so unauthenticated remote attackers cannot reach the vulnerable endpoint.
