An issue was discovered in dnaTools dnaLIMS 4-2015s13. dnaLIMS is vulnerable to a NUL-terminated directory traversal attack allowing an unauthenticated attacker to access system files readable by the web server user (by using the viewAppletFsa.cgi seqID parameter).
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.
