CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-2773 is a high-severity OS Command Injection (CWE-78) vulnerability in Bectechnologies Router Firmware. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-2773 is a command injection vulnerability in the management interface of multiple BEC Technologies routers. The flaw resides in the sys ping functionality and stems from insufficient validation of user-supplied input before it is passed to a system call, enabling remote code execution. The interface listens on TCP port 22 by default, and the issue is tracked as ZDI-CAN-25903 with a CVSS 3.0 score of 7.2.
Although authentication is required, the existing mechanism can be bypassed, allowing an attacker who reaches the interface to execute arbitrary code on the device with the privileges of the management process. Successful exploitation grants an attacker full control over the router, including the ability to alter configuration, intercept traffic, or use the device as a pivot point.
The sole advisory reference points to ZDI-25-187 without detailing specific patches or workarounds in the supplied information. The EPSS score rose from a low baseline to a peak of 0.0141 on 2026-02-17 before receding to the current value of 0.0014, indicating a period of increased exploitation interest after disclosure.

mechanism can be bypassed. The specific flaw exists within the management interface, which listens on TCP port 22 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-25903.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
