Zenoss is prone to the following security vulnerabilities:
1. Multiple arbitrary command-execution vulnerabilities
2. Multiple HTML-injection vulnerabilities
3. An open-redirection vulnerability
4. Multiple directory-traversal vulnerabilities
5. Multiple information-disclosure vulnerabilities
6. A code-execution vulnerability
An attacker can exploit these issues to retrieve arbitrary files, redirect a user to a potentially malicious site, execute arbitrary commands, execute HTML and script code in the context of the affected site, steal cookie-based authentication credentials to perform unauthorized actions in the context of a user's session, or disclose sensitive-information.
Zenoss 3.2.1 and prior are vulnerable.
# Zenoss <= 3.2.1 Remote Post-Authentication Command Execution #################
# o Requires: Credentials for a user with "ZenManager" or "Manager" roles.
# o Tested: Zenoss 3.2.1
# o Default port: 8080
