CVE-2024-8933

Estado: AplazadaAlta (7.5)—

CWE-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel vulnerability exists that could cause retrieval of password hash that could lead to denial of service and loss of confidentiality and integrity of controllers. To be successful, the attacker needs to inject themself inside the logical network while a valid user uploads or downloads a project file into the controller.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
