Estado: ModificadaMedia (6.1)—

A stored Cross Site Scripting (XSS) vulnerability in Esri ArcGIS Server feature services versions 10.8.1 and 10.9 (only) feature services may allow a remote, unauthenticated attacker to pass and store malicious strings via crafted queries which when accessed could potentially execute arbitrary JavaScript code in the user’s browser.

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).
