Technical Analysis

CVE-2020-9372 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A proof-of-concept (PoC) exploit exists for CVE-2020-9372. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
