CVE-2011-4559
Estado: ModificadaAlta (7.5)—💥 Exploit
SQL injection vulnerability in the Calendar module in vTiger CRM 5.2.1 and earlier allows remote attackers to execute arbitrary SQL commands via the onlyforuser parameter in an index action to index.php.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.34%
- Percentil entre todas las CVEs puntuadas: 70
- Fecha de la puntuación: 6/10/2026
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.
