CVE-2021-35493

Estado: ModificadaMedia (5.4)—

The WebFOCUS Reporting Server and WebFOCUS Client components of TIBCO Software Inc.'s TIBCO WebFOCUS Client, TIBCO WebFOCUS Installer, and TIBCO WebFOCUS Reporting Server contain easily exploitable Stored and Reflected Cross Site Scripting (XSS) vulnerabilities that allow a low privileged attacker to social engineer a legitimate user with network access to execute scripts targeting the affected system or the victim's local system. A successful attack using this vulnerability requires human interaction from a person other than the attacker. Affected releases are TIBCO Software Inc.'s TIBCO WebFOCUS Client: versions 8207.27.0 and below, TIBCO WebFOCUS Installer: versions 8207.27.0 and below, and TIBCO WebFOCUS Reporting Server: versions 8207.27.0 and below.

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).
