Hewlett-Packard OpenView Operations OVTrace Buffer Overflow Vulnerabilities iDefense Security Advisory 08.09.07 http://labs.idefense.com/intelligence/vulnerabilities/ Aug 09, 2007 I. BACKGROUND OpenView Operations software is a suite of network management tools used to monitor events on, and evaluate the performance of, hosts on the network. The OVTrace component of this suite is used to log the actions being taken by the other components of the suite in order to debug any problems that may be occurring. More information can be found at the following link. http://h20229.www2.hp.com/products/ovowin/index.html II. DESCRIPTION Remote exploitation of multiple stack-based buffer overflow vulnerabilities in Hewlett-Packard Development Co.'s OpenView Operations for Windows OVTrace service may allow an attacker to execute arbitrary code with SYSTEM privileges. The vulnerabilities exist within functions responsible for handling requests. These functions take a string from the request and copy it into fixed-size stack buffers. Since the length has not been properly validated, this results in an exploitable stack-based buffer overflow. III. ANALYSIS Exploitation of these vulnerabilities results in arbitrary code execution with SYSTEM privileges. The OVTrace service, while not crucial to normal operations, is started by default. The OVTrace service is also present on systems that have only the management console installed as well as systems that have a full installation of the server and console installed. IV. DETECTION iDefense has confirmed the existence of these vulnerabilities in HP OpenView version A.07.50 for Windows, with all patches applied as of Jun 27, 2007. Previous versions may also be affected. V. WORKAROUND Employing firewalls to limit access to the affected service will mitigate exposure to these vulnerabilities. VI. VENDOR RESPONSE Hewlett-Packard Co. has addressed these vulnerabilities by releasing patches for all HP OpenView products that contain the Shared Trace Service component.
