CVE-2023-24515
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 · uneditedServer-Side Request Forgery (SSRF) vulnerability in API checker of Pandora FMS. Application does not have a check on the URL scheme used while retrieving API URL. Rather than validating the http/https scheme, the application allows other scheme such as file, which could allow a malicious user to fetch internal file content. This issue affects Pandora FMS v767 version and prior versions on all platforms.
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 confidenceServer-Side Request Forgery (SSRF) vulnerability in Pandora FMS API checker. The application fails to validate the URL scheme when retrieving API URLs, permitting arbitrary schemes such as file:// instead of restricting to http/https. This allows a malicious user to access internal file content on the host system by supplying a file:// URL.

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 installed Pandora FMS versionAccess the Pandora FMS administration console or check the version file in the installation directory. Common locations include the login page or system information page within the web interface.Affected if The installed version is 767 or any version lower than 767.
-
Locate the API checker functionalityNavigate through the Pandora FMS web interface to find the API URL checker feature. This is typically found under Administration > Modules > API or similar configuration paths where URL-based API health checks can be configured.Affected if The API checker functionality exists and is accessible in the installed version.
-
Verify API checker is configured with custom URLsExamine the API checker configuration to see if custom URLs are being used for API endpoint validation. Look for any configured API endpoint URLs that could be modified by a user.Affected if Users can configure or modify API endpoint URLs within the system.
-
Check URL scheme validation implementationReview the Pandora FMS source code or configuration files related to the API checker. Look for code that handles URL parsing and validation, specifically examining whether scheme whitelist (http/https) enforcement is present.Affected if No scheme validation exists, or the validation allows schemes other than http and https (such as file, ftp, gopher).
A user is affected if their Pandora FMS version is 767 or lower AND the API checker feature is accessible, since the lack of URL scheme validation allows file:// URLs to be processed.

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.
From vendor dataImplement strict URL scheme validation in the API checker to only allow http and https schemes, rejecting all other schemes including file, ftp, and others. Alternatively, upgrade to a patched version of Pandora FMS when available.
