CVE-2021-22155
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn Authentication Bypass vulnerability in the SAML Authentication component of BlackBerry Workspaces Server (deployed with Appliance-X) version(s) 10.1, 9.1 and earlier could allow an attacker to potentially gain access to the application in the context of the targeted user’s account.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an authentication bypass vulnerability in the SAML authentication component of BlackBerry Workspaces Server. An attacker could potentially bypass SAML authentication mechanisms to gain unauthorized access to the application in the context of targeted user accounts. The vulnerability likely involves improper validation or processing of SAML assertions during the authentication flow.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed BlackBerry Workspaces Server versionAccess the server administration console or check the product version through the built-in about/version information page. If command-line access is available, consult the installation logs or use the server management utilities to retrieve the exact version number.Affected if The installed version is 9.1 or earlier, or exactly version 10.1.
-
Confirm SAML authentication is enabledLog into the BlackBerry Workspaces Server administration interface and navigate to the authentication settings or security configuration section. Look for SAML-based authentication settings and verify whether SAML authentication is currently active for user access.Affected if SAML authentication is enabled and the server version falls within the affected range.
-
Inspect SAML configuration for assertion handlingReview the SAML configuration files or settings within the administration panel. Check for the SAML service provider metadata, identity provider settings, and how SAML assertions are processed during the authentication flow.Affected if SAML is configured and the version is affected, indicating potential improper validation of SAML assertions.
-
Verify authentication endpoint behaviorIf you have access to authentication logs or can perform a controlled test, examine the server response when a SAML assertion is submitted. Look for whether the server validates all assertion attributes and signatures properly.Affected if The server accepts SAML assertions without proper validation (requires log review or controlled testing in a non-production environment).
A user is affected if their BlackBerry Workspaces Server is version 9.1 or earlier, or exactly version 10.1, and SAML authentication is enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-supplied patch or upgrade to a fixed version of BlackBerry Workspaces Server (beyond 10.1/9.1). If immediate patching is not possible, review and harden SAML configuration settings, disable vulnerable authentication paths, and implement additional monitoring on authentication endpoints.
