CVE-2021-3017

Status: ModifiedHigh (7.5)—💥 Exploit

The web interface on Intelbras WIN 300 and WRN 342 devices through 2021-01-04 allows remote attackers to discover credentials by reading the def_wirelesspassword line in the HTML source code.

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
