CVE-2025-9161

Status: AnalyzedHigh (7.3)—

A security issue exists within FactoryTalk Optix MQTT broker due to the lack of URI sanitization. This flaw enables the loading of remote Mosquito plugins, which can be used to achieve remote code execution.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

UI:R (interacción del usuario) y PR:L (requiere privilegios locales) clasifican como ejecución en cliente. CWE-77 (improper neutralization) y carga de plugins remotos sin sanitización permiten RCE. El contexto de MQTT broker y plugins sugiere posible escalada.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
