Versions of the Apache HTTPD server with wildcard DNS enabled and UseCanonicalName disabled, are vulnerable to a cross-site scripting attack.
Apache HTTPD servers versions 2.0.42 and prior, and 1.3.26 and prior, with wildcard DNS enabled and UseCanonicalName disabled, are vulnerable to a cross-site scripting attack via the error page. Only versions 2.0 to 2.0.33 have UseCanonicalName disabled by default. All other versions had UseCanonicalName enabled by default and are not vulnerable unless this option is disabled.
The victim will be presented with information which the compromised site did not wish their visitors to be subjected. This could be used to "sniff" sensitive data from within the web page, including passwords, credit card numbers, and any arbitrary information the user inputs.
This issue is resolved in Apache HTTPD Server versions 1.3.27 and 2.0.43.
