Official description

Path traversal vulnerability in the BugTracker.NET file download component. The parameter used to specify the file name does not properly validate user-supplied paths. An authenticated remote attacker could enter a manipulated path to access files located outside the intended directory. Successful exploitation could allow the attacker to read system files accessible to the account used by the application.

The underlying weakness: Path Traversal: '../filedir'

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize../ sequences that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
