CVE-2021-22133
Description
A flaw was found in the Elastic APM agent for Go in several versions, where it can leak sensitive HTTP header information when logging the details during an application panic. Normally, the APM agent will sanitize sensitive HTTP header details before sending the information to the APM server. During an application panic, it is possible the headers will not be sanitized before being sent. The highest threat from this vulnerability is to confidentiality.
Statement
Several components in the below products include an old reference to go.elastic.co/apm in their go.sum files, however no code is included. These components are thus not affected by this vulnerability: ** OpenShift Container Platform ** OpenShift Virtualization ** OpenShift Container Storage 4 ** Red Hat Advanced Cluster for Kubernetes (RHACM)
In Red Hat OpenStack Platform, because the flaw's impact is low and the Elastic APM agent is not directly used by the director-operator, no update will be provided at this time for the operator containers.
Common Vulnerability Scoring System (CVSS) Score Details
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).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Logging sensitive user data, full path names, or system information often provides attackers with an additional, less-protected path to acquiring the information.
