CVE-2024-40324

Estado: ModificadaMedia (5.4)—💥 PoC

A CRLF injection vulnerability in E-Staff v5.1 allows attackers to insert Carriage Return (CR) and Line Feed (LF) characters into input fields, leading to HTTP response splitting and header manipulation.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
