Xitami 2.5b installs the testcgi.exe program by default in the cgi-bin directory, which allows remote attackers to gain sensitive configuration information about the web server by accessing the program.

Xitami 2.5d4 and earlier allows remote attackers to crash the server via an HTTP request to the /aux directory.

Imatix Xitami 2.5 b5 does not properly terminate certain Keep-Alive connections that have been broken or closed early, which allows remote attackers to cause a denial of service (crash) via a large number of concurrent sessions.

Cross-site scripting (XSS) vulnerability in Errors.gsl in Imatix Xitami 2.5b4 and 2.5b5 allows remote attackers to inject arbitrary web script or HTML via the (1) Javascript events, as demonstrated via an onerror event in an IMG SRC tag or (2) User-Agent field in an HTTP GET request.
