CVE-2023-1719

Estado: ModificadaCrítica (9.8)—

Global variable extraction in bitrix/modules/main/tools.php in Bitrix24 22.0.300 allows unauthenticated remote attackers to (1) enumerate attachments on the server and (2) execute arbitrary JavaScript code in the victim's browser, and possibly execute arbitrary PHP code on the server if the victim has administrator privilege, via overwriting uninitialised variables.

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).
