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 the installed Access Manager versionCheck the product version through the Access Manager administrative console, or use system information commands (such as 'rpm -q' on Linux or checking Windows Programs and Features) to determine the exact version number of Micro Focus Access Manager installedAffected if The installed version is lower than 4.5.3.3 (for example, 4.5.2, 4.5.1, or earlier releases)
-
Confirm Access Manager authentication services are activeLog into the Access Manager administrative interface and verify that the authentication framework (NAM, Identity Server, or similar authentication components) is enabled and configuredAffected if Authentication services are enabled and the installed version is below 4.5.3.3
-
Review authentication configuration settingsInspect the authentication configuration files or console settings to confirm that the NAM Identity Server or authentication gateway is operational and processing login requestsAffected if The authentication module is active and the version is below 4.5.3.3
You are affected if Micro Focus Access Manager is installed with any version lower than 4.5.3.3 and authentication services are enabled.
