Apache · Apache Directory Studio · CVE-2021-33900
**Name of the Vulnerable Software and Affected Versions**
Apache Directory Studio versions prior to 2.0.0.v20210213-M16
**Description**
The issue is related to the absence of protection for service data. An attacker could exploit this to disclose protected information. The problem arises when configured StartTLS encryption is not applied with SASL authentication mechanisms like DIGEST-MD5 and GSSAPI, and when any configured SASL confidentiality layer is not applied.
**Recommendations**
For versions prior to 2.0.0.v20210213-M16, update to a version that includes the fix for this issue to ensure that StartTLS encryption and SASL confidentiality layers are properly applied. As a temporary workaround, consider restricting the use of SASL authentication mechanisms until a patch is available.
