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 · unedited
Dell EMC OpenManage Server Administrator (OMSA) versions prior to 9.1.0.3 and prior to 9.2.0.4 contain a web parameter tampering vulnerability. A remote unauthenticated attacker could potentially manipulate parameters of web requests to OMSA to create arbitrary files with empty content or delete the contents of any existing file, due to improper input parameter validation

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 · high confidence

Dell EMC OpenManage Server Administrator contains a web parameter tampering vulnerability where improper input validation allows a remote unauthenticated attacker to manipulate web request parameters. Attackers can create arbitrary empty files anywhere on the system or delete contents of existing files by tampering with web parameters.

MitigationUpgrade OMSA to version 9.1.0.3 or 9.2.0.4 or later to obtain the patch for proper input parameter validation.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify OMSA installation exists
    Check for Dell EMC OpenManage Server Administrator installation. On Windows, look in Program Files for 'Dell\OpenManage' or check registry key HKLM\SOFTWARE\Dell\OpenManage. On Linux, run 'rpm -qa | grep -i openmanage' or 'dpkg -l | grep -i openmanage'.
    Affected if OMSA is not installed on the system.
  2. Identify installed OMSA version
    On Windows, check registry key HKLM\SOFTWARE\Dell\OpenManage\OMSA\InstalledVersion or view version info in Add/Remove Programs. On Linux, run 'omreport about' or check RPM/DEB package version with 'rpm -qa | grep OpenManage'
    Affected if The installed version matches one of the affected versions: 9.1, 9.1.0.1, 9.1.0.2, 9.2, 9.2.0.1, or 9.2.0.2.
  3. Confirm web service is running
    Check if OMSA web server is active. On Windows, verify the 'Dell OpenManage Server Administrator' service status. On Linux, run 'service dellsrv status' or check for OMSA processes. The web interface typically listens on port 1311.
    Affected if The OMSA web service (omaws) is running and accessible.
  4. Verify web interface accessibility
    Check if the OMSA web port (default 1311) is listening and accessible from the network. Run 'netstat -an | grep 1311' or 'ss -tlnp | grep 1311' to confirm the port is in LISTEN state and review firewall rules.
    Affected if Port 1311 (or configured OMSA web port) is open and accessible to network attackers.

A system is affected if Dell EMC OpenManage Server Administrator versions 9.1 through 9.2.0.2 are installed with the web service running and accessible.
