CVE-2025-7850 is a critical-severity OS Command Injection (CWE-78) vulnerability in Tp-Link Er8411 Firmware. Its CVSS base score is 9.3 (Critical).
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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-7850 is a command injection vulnerability (CWE-78) affecting Omada gateways. The flaw is present in the web portal component and can be reached only after an administrator has authenticated.
An attacker with administrative credentials on an adjacent network can supply crafted input that results in arbitrary command execution. Successful exploitation yields high impact to device confidentiality, integrity, and availability, along with limited impact beyond the vulnerable component.
Vendor advisories and firmware updates addressing the issue are referenced in Omada Networks support documentation and related product pages.
The EPSS score rose from a low baseline of 0.0066 to a peak of 0.0194 on 2026-02-20 before receding, indicating post-disclosure exploitation interest that later subsided.

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).

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
