CVE-2019-19364

Status: ModifiedHigh (7.8)—

A weak malicious user can escalate its privilege whenever CatalystProductionSuite.2019.1.exe (version 1.1.0.21) and CatalystBrowseSuite.2019.1.exe (version 1.1.0.21) installers run. The vulnerability is in the form of DLL Hijacking. The installers try to load DLLs that don’t exist from its current directory; by doing so, an attacker can quickly escalate its privileges.

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).
