Two weaknesses and multiple vulnerabilities have been discovered in NetSaro Enterprise Messenger, which can be exploited by malicious, local users to disclose sensitive information, by malicious users to conduct script insertion attacks, and by malicious people to disclose sensitive information and conduct cross-site scripting and cross-site request forgery attacks.
1) The application stores the administrator's credentials in Base64-encoded format in the configuration.xml file.
2) The application stores user credentials in clear text in the Db/NetSaro.fdb file.
3) Input passed via the URL is not properly verified before being used to display files. This can be exploited to disclose the source code via URL-encoded NULL bytes.
4) Input passed via the "FromUser" parameter to archive-announcement.nsp and the "FromUsers" parameter to archive-message.nsp 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.
5) Input passed via the "name" and "description" parameters to department-add.nsp and the "username", "firstname", "lastname", "jobtitle", and "email" parameters to user-add.nsp is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
6) The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to e.g. add new users by tricking a logged in administrative user into visiting a malicious web site.
The weaknesses and vulnerabilities are confirmed in version 2.1. Other versions may also be affected.
