Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
lsFusion Platform web-client, versions up to and including 6.1, is vulnerable to path traversal through the sid argument handled by the file upload request handler. A remote attacker can manipulate that argument to reach files outside the intended directory. The source gives no fixed version, so no fix is listed; a publicly disclosed exploit exists.
