CVE-2020-36283

Estado: ModificadaAlta (8.8)—

HID OMNIKEY 5427 and OMNIKEY 5127 readers are vulnerable to CSRF when using the EEM driver (Ethernet Emulation Mode). By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to upload a configuration file to the device. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.

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).
