CVE-2006-6661
Estado: ModificadaAlta (7.5)—💥 Exploit
Variable overwrite vulnerability in blog.php in PHP-Update 2.7 and earlier allows remote attackers to overwrite arbitrary program variables and execute arbitrary PHP code via multiple vectors that use the extract function, as demonstrated by the (1) f, (2) newmessage, (3) newusername, (4) adminuser, and (5) permission parameters.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 6.65%
- Percentil entre todas las CVEs puntuadas: 94
- 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.
