Executive Summary

This vulnerability in Apache CloudStack allows an unauthorized actor to access sensitive information through the LDAP authentication plugin. Specifically, any authenticated user can list LDAP configurations via the listLdapConfigurations API, which is available to default roles by default.

Detection Guidance

Check Apache CloudStack logs for unauthorized access to the listLdapConfigurations API. Monitor API calls to detect unusual activity from authenticated users.

Impact Analysis

An attacker with access to the system could exploit this to view LDAP configuration details, potentially exposing sensitive authentication data like server addresses, bind credentials, or user attributes. This could lead to further unauthorized access or data breaches.

Compliance Impact

This vulnerability could violate compliance requirements such as GDPR or HIPAA by exposing sensitive authentication data. Unauthorized access to LDAP configurations may result in data breaches, leading to legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Upgrade Apache CloudStack to version 4.20.3.1, 4.22.1.1, or later. Restrict access to the listLdapConfigurations API to authorized roles only.
