Description:
Felipe Aragon and Alec Storm have reported some vulnerabilities and security issues in HTTP File Server, which can be exploited by malicious people to disclose system information, conduct spoofing and cross-site scripting attacks, bypass certain security restrictions, manipulate data, and potentially compromise a vulnerable system.
1) The application does not correctly log certain input. This can be exploited to e.g. spoof the username or inject arbitrary content into the logfile when logging in.
2) Certain input is not properly sanitised before being returned to a user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected server.
3) It is possible to disclose certain information (e.g. number of connections, transfer speed, traffic statistics, or uptime) by sending specially crafted request containing template symbols.
4) The application does not correctly handle the username before using it to create the file name of the logfile. This can be exploited to create directories, append data to files, or to cause a buffer overflow by sending specially crafted requests to a vulnerable server.
Successful exploitation allows the execution of arbitrary code, but requires that the "%user%" template symbol is used to define the name of the logfile.
Solution:
Update to version 2.2d.
