A cross-site scripting vulnerability is reported to exist in MailPost version 5.1.1sv and possibly earlier versions.
According to a report by ProCheckUp, MailPost is vulnerable to a Cross-Site Scripting attack by adding a trailing '/' character to the executable filename. The application fails and returns error information to the client without any filtering, this information includes user input and discloses the webroot path of the server.
The victim site may present malicious content to their visitors. This could be used to "sniff" sensitive data from within the web page and cookie files, including passwords, credit card numbers, and any arbitrary information the user inputs.
The CERT/CC is currently unaware of a practical solution to this problem.
It may be possible to configure the error pages of the application to mitigate this vulnerability.
Thanks to ProCheckUp for reporting this vulnerability.
