VULNERABILITY DETAILS

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett-Packard Operations Manager. Authentication is not required to exploit this vulnerability.

The specific flaw exists due to a hidden account present within the Tomcat users XML file. Using this account a malicious user can access the org.apache.catalina.manager.HTMLManagerServlet class. This is defined within the catalina-manager.jar file installed with the product. This servlet allows a remote user to upload a file via a POST request to /manager/html/upload. If an attacker uploads malicious content it can then be accessed and executed on the server which leads to arbitrary code execution under the context of the SYSTEM user.

ADDITIONAL DETAILS Hewlett-Packard has issued an update to correct this vulnerability. More details can be found at:
