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
Improper Input Validation vulnerability of Authenticated User in Progress LoadMaster allows : OS Command Injection.This issue affects:  Product Affected Versions LoadMaster From 7.2.55.0 to 7.2.60.1 (inclusive)    From 7.2.49.0 to 7.2.54.12 (inclusive)    7.2.48.12 and all prior versions Multi-Tenant Hypervisor 7.1.35.12 and all prior versions ECS All prior versions to 7.2.60.1 (inclusive)

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

Improper input validation in Progress LoadMaster allows authenticated users to inject OS commands, enabling complete system compromise. This is a command injection vulnerability requiring valid authentication, but with CVSS 9.8 indicating trivial exploitability once credentials are obtained.

MitigationUpgrade LoadMaster, Multi-Tenant Hypervisor, and ECS to vendor-provided patched versions. As immediate workarounds, limit administrative access to trusted personnel only and restrict network exposure to the management interface.

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. Identify if Progress LoadMaster is deployed
    Look for the LoadMaster web management interface (typically on port 443/8443), or check running processes/services for LoadMaster-related components.
    Affected if LoadMaster is found running in the environment
  2. Determine the installed LoadMaster version
    Log into the LoadMaster web UI and navigate to System Configuration > System Administration > System Debug > Version, or use the 'lmutil' command-line tool if available. Compare the version number against the affected ranges.
    Affected if The installed version is <= 7.2.48.12, OR between 7.2.49.0 and 7.2.54.12 inclusive, OR between 7.2.55.0 and 7.2.60.0 inclusive (anything below 7.2.61.0)
  3. Verify management interface network exposure
    Check firewall rules, network ACLs, or cloud security groups to determine if the LoadMaster management interface (ports 443, 8443) is accessible from untrusted networks or the internet.
    Affected if The management interface is exposed to the internet or untrusted internal networks
  4. Confirm authentication requirements
    Review access controls and confirm that LoadMaster administrative accounts use strong, unique passwords and are not using default credentials.
    Affected if Weak, default, or shared administrative credentials are in use, or if the account lockout policy is not enforced

The environment is affected if LoadMaster is running with a version below 7.2.61.0 and the management interface is accessible to attackers who could obtain valid credentials.

dbcve · scoped
Upgrade available Upgrade to 7.2.61.0 or later
Fixed in 7.2.61.0
Interim mitigation

Upgrade LoadMaster, Multi-Tenant Hypervisor, and ECS to vendor-provided patched versions. As immediate workarounds, limit administrative access to trusted personnel only and restrict network exposure to the management interface.

Recommended fix High confidence

LoadMaster 7.2.61.0 or later (for Multi-Tenant Hypervisor and ECS, upgrade to the version that supersedes 7.1.35.12 and 7.2.60.1 respectively)

  1. 1. Identify the current LoadMaster version by navigating to the LoadMaster User Interface > Help & Info > System Overview
  2. 2. Download LoadMaster version 7.2.61.0 or later from the Kemp Technologies support portal at support.kemptechnologies.com
  3. 3. Review the LoadMaster upgrade documentation for your deployment type (物理机/虚拟机/云)
  4. 4. Create a full backup of the current LoadMaster configuration before upgrading
  5. 5. Schedule a maintenance window as the upgrade may require a brief service interruption
  6. 6. Apply the upgrade by uploading the LoadMaster update through the web interface (LoadMaster User Interface > Updates > Install Update) or using the command line if preferred
  7. 7. After upgrade completes, verify the new version is 7.2.61.0 or later by checking Help & Info > System Overview
  8. 8. Confirm the LoadMaster services are functioning correctly and test critical workflows
Caveat Review Kemp release notes for 7.2.61.0 for any configuration or behavioral changes that may affect your deployment; always test in a staging environment first
