CVE-2000-1205: XSS
Cross site scripting vulnerabilities in Apache 1.3.0 through 1.3.11 allow remote attackers to execute script as other web site visitors via (1) the printenv CGI (printenv.pl), which does not encode its output, (2) pages generated by the apsenderrorresponse function such as a default 404, which does not add an explicit charset, or (3) various messages that are generated by certain Apache modules or core code. NOTE: the printenv issue might still exist for web browsers that can render text/plain content types as HTML, such as Internet Explorer, but CVE regards this as a design limitation of those browsers, not Apache. The printenv.pl/acuparam vector, discloser on 20070724, is one such variant.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Remove
Remove
printenv.pl (printenv CGI)from your environment.Remove or disable the printenv CGI (printenv.pl) from the server (e.g., from cgi-bin) if it is not required; printenv.pl does not encode its output and can enable XSS.
- Configuration
Ensure error responses (for example default 404 pages generated by ap_send_error_response) include an explicit charset in the Content-Type header so they are not misinterpreted by browsers as HTML.
Apache Http Server (ap_send_error_response) error response charset = explicit charset - Configuration
Ensure messages generated by Apache modules or core code are HTML-encoded or escaped before being sent to clients to prevent cross-site scripting.
Apache Http Server (modules/core-generated messages) output encoding / HTML escaping = encode or escape HTML special characters
