CVE-2024-8540
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 · uneditedInsecure permissions in Ivanti Sentry before versions 9.20.2 and 10.0.2 or 10.1.0 allow a local authenticated attacker to modify sensitive application components.
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 confidenceIvanti Sentry versions prior to 9.20.2, 10.0.2, and 10.1.0 contain insecure file system or application permissions that allow a local authenticated user to modify sensitive application components, potentially leading to privilege escalation or tampering of application functionality.

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 Ivanti Sentry installationLocate Ivanti Sentry installation directory or check installed programs list on the systemAffected if Ivanti Sentry is installed on the system
-
Identify installed Sentry versionCheck the application version through the Sentry administrative interface, installer properties, or version file in the installation directoryAffected if Version is < 9.20.2, or = 10.0.1, or version 10.0.x is < 10.0.2, or version 10.1.x is < 10.1.0
-
Review file system permissions on application directoriesExamine read/write/execute permissions on the Sentry installation folder and subdirectories, focusing on configuration and executable locationsAffected if Local authenticated users have write or modify permissions to sensitive application directories or configuration files
-
Audit local user account privilegesReview local user accounts and their group memberships on the Sentry server, checking which users can access the Sentry installation or configuration areasAffected if Non-administrative local users have elevated permissions that allow modification of application components
You are affected if Ivanti Sentry is installed and the version falls within the vulnerable range while local users possess excessive permissions on application directories.

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.
dbcve · scoped9.20.2
Upgrade Ivanti Sentry to version 9.20.2, 10.0.2, or 10.1.0 or later. As a compensating control, restrict local user permissions to least-privilege and audit administrative accounts.
Ivanti Sentry version 9.20.2 (for 9.x branch) or version 10.0.2/10.1.0 (for 10.x branch)
- 1. Back up the current Ivanti Sentry installation and database before proceeding with the upgrade
- 2. Download the fixed version of Ivanti Sentry (version 9.20.2 for the 9.x branch, or version 10.0.2/10.1.0 for the 10.x branch) from the official Ivanti download portal
- 3. Review the official Ivanti Sentry upgrade guide for version-specific installation prerequisites
- 4. Execute the upgrade installer on the Sentry server following standard upgrade procedures
- 5. Verify the upgrade was successful by checking the Sentry administration console
- 6. Confirm that the insecure permissions vulnerability is resolved by reviewing file and directory permissions on sensitive application components
