CVE-2022-38725
An integer overflow in the RFC3164 parser in One Identity syslog-ng 3.0 through 3.37 allows remote attackers to cause a Denial of Service via crafted syslog input that is mishandled by the tcp or network function. syslog-ng Premium Edition 7.0.30 and syslog-ng Store Box 6.10.0 are also affected.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.40%
- Percentil entre todas las CVEs puntuadas: 84
- 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.
