CVE-2010-2094
Múltiples vulnerabilidades de formato de cadena en la extensión phar en PHP v5.3 anterior a v5.3.2, permite a atacantes dependientes del contexto obtener información sensible (contenido de la memoria) y posiblemente ejecutar código de su elección a través de una URI phar:// que no se ha manejado adecuadamente por las funciones (1) phar_stream_flush, (2) phar_wrapper_unlink, (3) phar_parse_url, o (4) phar_wrapper_open_url en ext/phar/stream.c; y la función (5) phar_wrapper_open_dir en ext/phar/dirstream.c, que provoca un error en la función php_stream_wrapper_log_error.
CVSS
- Puntuación base
- 6.8
- Versión
- 2.0
- Vector
- AV:N/AC:M/Au:N/C:P/I:P/A:P
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 13 %
- Percentil entre todas las CVEs puntuadas
- 96
- Fecha de la puntuación
- 21/10/2026
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.
