Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

CWE-312

Confidentiality

Technical Impact: Read Application Data

An attacker with access to the system could read sensitive information stored in cleartext (i.e., unencrypted). Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information.
