Affected versions of this package are vulnerable to Information Disclosure. When serving resources from a network location using the NTFS file system, affected versions were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances.
