- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
An
authenticated directory traversal vulnerability in file upload functionality has
been identified in Archer MR600 (v2, v3 & v5) and TL-MR6400 v8. Due to insufficient validation of user-supplied file
information, an authenticated remote attacker with access to the affected
upload functionality could upload a specially crafted file and cause it to be
written outside the intended directory.
Successful
exploitation could allow an authenticated remote attacker to write files to
unintended locations, potentially overwriting or modifying files
accessible to the affected service; arbitrary code execution has not
been demonstrated.
