CVE-2011-1081
Estado: ModificadaMedia (5)—💥 Exploit
modrdn.c in slapd in OpenLDAP 2.4.x before 2.4.24 allows remote attackers to cause a denial of service (daemon crash) via a relative Distinguished Name (DN) modification request (aka MODRDN operation) that contains an empty value for the OldDN field.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
- Puntuación base: 5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 14%
- Percentil entre todas las CVEs puntuadas: 97
- Fecha de la puntuación: 7/10/2026
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.
