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.
-
Confirm HP Data Protector installationCheck the system for HP Data Protector software by reviewing installed programs in Windows Add/Remove Programs, or by searching for HP Data Protector directories in Program FilesAffected if HP Data Protector is not found, the system is not affected by this vulnerability
-
Identify HP Data Protector for Personal Computers versionOpen the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall or check the program's About/Version information from the application menu to locate the exact version numberAffected if The installed version is exactly 7.0, indicating the system is vulnerable
-
Identify HP Data Protector Notebook Extension versionOpen the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall or check the program's About/Version information from the application menu to locate the exact version numberAffected if The installed version is exactly 6.20, indicating the system is vulnerable
-
Verify Data Protector services are runningOpen Services.msc and check for HP Data Protector services, or use the command 'sc query' to list running services related to Data ProtectorAffected if The vulnerable version is installed AND the Data Protector service is actively running, creating an exploitable condition
A system is affected if it has HP Data Protector for Personal Computers version 7.0 or HP Data Protector Notebook Extension version 6.20 installed with the service running, as this vulnerability allows unauthenticated remote code execution.
