CVE-2024-11736: Cleartext Storage of Sensitive Information in an Environment Variable
A vulnerability was found in Keycloak. Admin users may have to access sensitive server environment variables and system properties through user-configurable URLs. When configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing.
AI Analysis
Technical Summary
The vulnerability CVE-2024-11736 in Keycloak involves the cleartext exposure of sensitive information through environment variables or system properties. Admin users configuring backchannel logout URLs or admin URLs can insert placeholders such as ${env.VARNAME} or ${PROPNAME}, which the server replaces with actual environment variable or system property values during URL processing. This unrestricted use by admin users can lead to unintended disclosure of sensitive server environment data. Red Hat has addressed this issue in the Red Hat build of Keycloak version 26.0.8, releasing updated container images for OpenShift deployments.
Potential Impact
The vulnerability allows disclosure of sensitive environment variables and system properties to admin users who configure URLs with placeholders. This can lead to exposure of sensitive server information in cleartext, impacting confidentiality. The CVSS score of 4.9 reflects a medium severity impact with no integrity or availability impact reported. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released fixed versions of the Red Hat build of Keycloak in version 26.0.8 images for OpenShift Container Platform. Users should update to these fixed versions to remediate the vulnerability. Before applying the update, ensure all previously released errata relevant to your system have been applied.
