Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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-2022-25075 is a command injection vulnerability (CWE-78) affecting the TOTOLink A3000RU router running firmware version V5.9c.2280_B20180512. The flaw resides in the Main function and permits arbitrary operating-system command execution when attacker-controlled input is processed through the QUERY_STRING parameter.

Unauthenticated attackers with network access can exploit the issue remotely without user interaction. Successful exploitation yields full control over the device, allowing arbitrary command execution that can result in confidentiality, integrity, and availability impacts consistent with the CVSS 9.8 rating.

Public references consist of proof-of-concept details hosted on GitHub; no vendor advisory, firmware patch, or official mitigation guidance is referenced in the supplied information. The EPSS score stands at 0.4209 with an identical recorded peak, indicating sustained exploitation interest but without a documented post-disclosure rise from a low baseline.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
prevents

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.

PR.PS-02 partial match
prevents

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).
