CVE-2012-1582

Estado: ModificadaMedia (4.3)—

Vulnerabilidad de ejecución de secuencias de comandos en sitios cruzados (XSS) en el analizador wikitext en MediaWiki v1.17.x antes de v1.17.3 y v1.18.x antes de v1.18.2 permite a atacantes remotos inyectar secuencias de comandos web o HTML a través de una página diseñada con "forged strip item markers", como se demuestra con la extensión CharInsert.

CVSS

Probabilidad de explotación (EPSS)

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).
