CVE-2020-10145

Status: ModifiedHigh (7.8)—

The Adobe ColdFusion installer fails to set a secure access-control list (ACL) on the default installation directory, such as C:\ColdFusion2021\. By default, unprivileged users can create files in this directory structure, which creates a privilege-escalation vulnerability.

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).
