Jigsaw /aux request could disclose path to Web root directory

jigsaw-aux-path-disclosure (9586) The risk level is classified as LowLow Risk


Jigsaw could allow a remote attacker to obtain the path to the Web root directory. If a remote attacker sends two requests for /aux, the attacker would cause an error message to be returned that would contain the full path to the Web root directory. An attacker can then use this information to prepare for further attacks against the affected Web server.
