CVE-2011-0534
Estado: ModificadaMedia (5)—
Apache Tomcat 7.0.0 through 7.0.6 and 6.0.0 through 6.0.30 does not enforce the maxHttpHeaderSize limit for requests involving the NIO HTTP connector, which allows remote attackers to cause a denial of service (OutOfMemoryError) via a crafted request.
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: 7.89%
- Percentil entre todas las CVEs puntuadas: 95
- 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).
