Mailenable: >> Mailenable Security Vulnerabilities
MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the InstanceScope parameter of /Mondo/lang/sys/Forms/CAL/compose.aspx. The InstanceScope value is not properly sanitized when processed via a GET request and is reflected inside a <script> block in the JavaScript variable var gInstanceScope. By supplying a crafted payload that terminates the existing PageLoad() function, inserts attacker-controlled script, and comments out remaining code, a remote attacker can execute arbitrary JavaScript in a victim’s browser. Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user.

MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the Message parameter of /Mobile/Compose.aspx. The Message value is not properly sanitized when processed via a GET request and is reflected into a JavaScript context in the response. By supplying a crafted payload that terminates the existing script block/function, injects attacker-controlled JavaScript, and comments out the remaining code, a remote attacker can execute arbitrary JavaScript in a victim’s browser when the victim opens the crafted reply URL. Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user.

Authenticated mail users, under specific circumstances, could add files with unsanitized content in public folders where the IIS user had permission to access. That action, could lead an attacker to store arbitrary code on that files and execute RCE commands.

MailEnable Enterprise Premium 10.23 was vulnerable to multiple directory traversal issues, with which authenticated users could add, remove, or potentially read files in arbitrary folders accessible by the IIS user. This could lead to reading other users' credentials including those of SYSADMIN accounts, reading other users' emails, or adding emails or files to other users' accounts.

MailEnable Enterprise Premium 10.23 did not use appropriate access control checks in a number of areas. As a result, it was possible to perform a number of actions, when logged in as a user, that that user should not have had permission to perform. It was also possible to gain access to areas within the application for which the accounts used were supposed to have insufficient access.

MailEnable Enterprise Premium 10.23 was vulnerable to stored and reflected cross-site scripting (XSS) attacks. Because the session cookie did not use the HttpOnly flag, it was possible to hijack the session cookie by exploiting this vulnerability.

MailEnable Enterprise Premium 10.23 was vulnerable to XML External Entity Injection (XXE) attacks that could be exploited by an unauthenticated user. It was possible for an attacker to use a vulnerability in the configuration of the XML processor to read any file on the host system. Because all credentials were stored in a cleartext file, it was possible to steal all users' credentials (including the highest privileged users).

In MailEnable Enterprise Premium 10.23, the potential cross-site request forgery (CSRF) protection mechanism was not implemented correctly and it was possible to bypass it by removing the anti-CSRF token parameter from the request. This could allow an attacker to manipulate a user into unwittingly performing actions within the application (such as sending email, adding contacts, or changing settings) on behalf of the attacker.
