Mitel OpenScape Accounting Management through V5 R1.1.0 could allow an authenticated attacker with administrative privileges to conduct a path traversal attack due to insufficient sanitization of user input. A successful exploit could allow an attacker to upload arbitrary files and execute unauthorized commands.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
