CVE-2022-25256

Estado: ModificadaMedia (6.1)—💥 PoC

SAS Web Report Studio 4.4 allows XSS. /SASWebReportStudio/logonAndRender.do has two parameters: saspfs_request_backlabel_list and saspfs_request_backurl_list. The first one affects the content of the button placed in the top left. The second affects the page to which the user is directed after pressing the button, e.g., a malicious web page. In addition, the second parameter executes JavaScript, which means XSS is possible by adding a javascript: URL.

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).

💥 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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
