DescriptionCVE.org
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.
