An issue was discovered in Pivotal Spring Framework before 3.2.18, 4.2.x
before 4.2.9, and 4.3.x before 4.3.5. Paths provided to the ResourceServlet
were not properly sanitized and as a result exposed to directory traversal
attacks.

It was discovered that Spring Framework incorrectly handled path inputs. An
attacker could possibly use this issue to read arbitrary files.
