CVE-2003-0245

Estado: ModificadaMedia (5)—💥 Exploit
Vulnerability in the apr_psprintf function in the Apache Portable Runtime (APR) library for Apache 2.0.37 through 2.0.45 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long strings, as demonstrated using XML objects to mod_dav, and possibly other vectors.
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: 63%
Percentil entre todas las CVEs puntuadas: 99
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.
