CVE-2020-10633

Status: ModifiedMedium (6.1)—

A non-persistent XSS (cross-site scripting) vulnerability exists in eWON Flexy and Cosy (all firmware versions prior to 14.1s0). An attacker could send a specially crafted URL to initiate a password change for the device. The target must introduce the credentials to the gateway before the attack can be successful.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
