CVE-2010-0999
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 · uneditedDirectory traversal vulnerability in Free Download Manager (FDM) before 3.0.852 allows remote attackers to create arbitrary files via directory traversal sequences in the name attribute of a file element in a metalink file.
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 confidenceDirectory traversal vulnerability in Free Download Manager before version 3.0.852 allows remote attackers to create arbitrary files on the target system by embedding directory traversal sequences (e.g., ../../) in the name attribute of file elements within metalink files. The application fails to properly sanitize file paths in metalink file parsing.

-
Identify installed Free Download Manager versionOpen Free Download Manager and navigate to Help > About, or check the program's version information in your system's installed programs list. Compare the version number against the affected ranges: versions 2, 2.1, 2.5.700, 2.5.704, 2.5.724, 3.0.843, 3.0.848, 3.0.850, or any version 3.0.851 or earlier.Affected if The installed version is 3.0.851 or lower, or matches any of the specific affected versions listed (2.x, 2.1, 2.5.7xx, 3.0.843, 3.0.848, 3.0.850)
-
Determine if metalink file processing is usedReview your download history or examine any .metalink files you have downloaded or processed with Free Download Manager. Check if the application has a metalink handler or parser feature enabled in its settings.Affected if You have processed or regularly process metalink files with the application
-
Inspect recent download activity for metalink filesAccess the application's download manager or log files to see if metalink files (.metalink extension) have been added as downloads. Look for entries in the download queue that reference metalink format.Affected if Metalink files appear in your download history or queue
-
Verify metalink parsing behaviorIf you have a test metalink file available, observe whether the application extracts files to locations outside the intended download directory when the metalink contains path elements with directory traversal sequences (../../).Affected if The application processes metalink files and allows path traversal outside the intended directory
You are affected if you are running any Free Download Manager version from 2.0 through 3.0.851 and have processed or intend to process metalink files with the application.

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 Free Download Manager to version 3.0.852 or later, which contains the patch for the directory traversal vulnerability in metalink file processing. Alternatively, avoid processing untrusted metalink files from unknown sources.
