PERTAIN_TOReport

wget CVE-2018-20483: xattr leaks URL userinfo (password) to file metadata

PERTAIN_TOProblem

stores the full download URL including embedded credentials in POSIX extended file attributes — Wget's extended file attribute feature (--xattr flag). Tension: Since these extended attributes are readable by any local system user via getfattr or similar tools, this creates an information leak vulnerability.

PERTAIN_TOSolution

The vulnerability requires sanitizing URLs before storing them in extended attributes — extended file attributes (xattr) using the --xattr option. Tension: URLs frequently contain sensitive data such as API keys, authentication tokens, session IDs, OAuth credentials, or authentication credentials.
