Jadaptive Maverick Synergy Server before 3.0.33 and 3.1.x before 3.1.7, and Maverick Legacy Server before 1.8.1, contain an improper path equivalence flaw in VirtualFileFactory.canonicalisePath that bypasses mount-level access policy. Authenticated users can supply paths with duplicate separators or dot segments to route operations to a less restrictive parent mount and read or write files the child mount denies.
CWE-41
