CVE-2022-25256
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
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- Puntuación base: 6.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.17%
- Percentil entre todas las CVEs puntuadas: 66
- Fecha de la puntuación: 6/10/2026
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.
