Apache Tomcat Discloses MS-DOS Pathname

  • Disclosed: 01.05.2022
  • Updated: 11.10.2026 11:20

Apache Tomcat 4.0.3, when running on Windows, allows remote attackers to obtain sensitive information via a request for a file that contains an MS-DOS device name such as lpt9, which leaks the pathname in an error message, as demonstrated by lpt9.xtp using Nikto.
