CeLa Link CLR-M20 devices allow unauthorized users to upload any file (e.g., asp, aspx, cfm, html, jhtml, jsp, or shtml), which causes remote code execution as well. Because of the WebDAV feature, it is possible to upload arbitrary files by utilizing the PUT method.

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.
