CVE-2026-26234

Estado: AnalizadaAlta (8.7)—

JUNG Smart Visu Server 1.1.1050 contains a request header manipulation vulnerability that allows unauthenticated attackers to override request URLs by injecting arbitrary values in the X-Forwarded-Host header. Attackers can manipulate proxied requests to generate tainted responses, enabling cache poisoning, potential phishing, and redirecting users to malicious domains.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

XSS/cache poisoning mediante manipulación de header X-Forwarded-Host genera respuestas tainted (drive-by). Requiere UI:P (interacción del usuario al acceder a caché envenenada). Impactos: phishing, suplantación y redirección maliciosa.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
