CVE-2023-1717

Estado: ModificadaCrítica (9.6)—

Prototype pollution in bitrix/templates/bitrix24/components/bitrix/menu/left_vertical/script.js in Bitrix24 22.0.300 allows remote attackers to 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 polluting `__proto__[tag]` and `__proto__[text]`.

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).
