Product Link: http://www.mailenable.com/default.asp ====================================================================== 4) Description of Vulnerability Secunia Research has discovered some vulnerabilities in MailEnable Web Mail Client, which can be exploited by malicious people to conduct cross-site scripting, cross-site request forgery, and script insertion attacks. 1) Scripts in email messages are not properly sanitised before being displayed in the email message. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when a user views a specially crafted email message. 2) Input passed to the "ID" parameter in mewebmail/base/default/lang/EN/right.asp, mewebmail/base/default/lang/EN/Forms/MAI/list.asp, and mewebmail/base/default/lang/EN/Forms/VCF/list.asp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Successful exploitation requires that the target user is logged in. 3) The application allows users to send messages via HTTP requests without performing any validity checks to verify the request. This can be exploited to change a user's settings by e.g. tricking a target user into visiting a malicious website. ====================================================================== 5) Solution Update to the latest version. http://www.mailenable.com/download.asp ====================================================================== 6) Time Table 06/02/2007 - Vendor notified. 06/02/2007 - Vendor response. 13/02/2007 - Request for status update. 13/02/2007 - Vendor response with fix information. 14/02/2007 - Public disclosure. ====================================================================== 7) Credits Discovered by JJ Reyes, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned the following CVE identifiers: * CVE-2007-0651 (XSS) * CVE-2007-0652 (CSRF) ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://corporate.secunia.com/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://corporate.secunia.com/secunia_research/33/ Secunia regularly hires new skilled team members.
