CVE-2007-5817
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 · unediteddialog.php in CONTENTCustomizer 3.1mp and earlier allows remote attackers to perform certain privileged actions via a (1) del, (2) delbackup, (3) res, or (4) ren action. NOTE: this issue can be leveraged to conduct cross-site scripting (XSS) and possibly other attacks.
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 confidenceThe dialog.php file in CONTENTCustomizer 3.1mp and earlier versions contains improper access control that allows remote attackers to execute privileged file operations (delete, delete backup, rename, resize) without authentication. This can be leveraged to conduct cross-site scripting (XSS) and potentially other attacks.

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.
-
Locate dialog.php file in CONTENTCustomizerSearch the web root directory for the file 'dialog.php' that belongs to CONTENTCustomizer, typically found in paths like /admin/, /include/, or /components/ directories.Affected if The dialog.php file exists in the CONTENTCustomizer installation directory.
-
Identify CONTENTCustomizer versionCheck the product version from the software documentation, version file, or any installer metadata. Compare against the affected version range of 3.1mp and earlier.Affected if The installed version is 3.1mp or any version earlier than 3.1mp.
-
Verify unauthenticated access to file operationsAttempt to access dialog.php directly via HTTP with parameters for the vulnerable operations: delete (e.g., ?action=delete&file=example.php), delete backup, rename, or resize without providing any authentication credentials.Affected if The server processes the file operation request without requiring authentication or authorization.
-
Inspect file operation parameters in dialog.phpExamine the source code of dialog.php and look for the parameters used to trigger file operations such as 'action', 'file', 'filename', 'backup', or 'resize' without checking user authentication or session validity.Affected if The code contains file operation handlers (delete, delete backup, rename, resize) that execute without authentication checks.
A user is affected if CONTENTCustomizer version 3.1mp or earlier is installed and the dialog.php file is accessible without authentication, allowing unauthenticated file operations.

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 dataUpgrade to a patched version of CONTENTCustomizer if available, or disable/remove the affected dialog.php component. Implement proper authentication and input validation/sanitization on all file operations.
