Oracle Application Server 10g Directory Traversal
------------------------------------------------------------------------
SUMMARY
"Oracle Application Server 10g offers a comprehensive solution for
developing, integrating, and deploying your enterprise's applications,
portals, and Web services. Based on a powerful and scalable J2EE server,
Oracle Application Server 10g provides complete business integration and
business intelligence suites, and best-of-breed portal software. Oracle
Application Server 10g is the only platform designed for grid computing as
well as full lifecycle support for Service-Oriented Architecture (SOA)."
A vulnerable server side component allows remote access to files outside
of the application's root directory with permissions of the LocalSystem
process. No authentication is required.
DETAILS
Vulnerable Systems:
* Oracle Application Server 10g Release 3 (10.1.3.0.0)
The server side component EmChartBean is part of the Oracle Enterprise
Manager 10g Application Server Control Software. EmChartBean is vulnerable
to a directory traversal attack.
The vulnerability can be exploited by sending an unauthenticated http GET
request. Remote access is granted to files outside of the application's
root directory with permissions of the Javaw.exe process, which by default
runs with LocalSystem privileges.
The server side component EmChartBean only exists at runtime, and is
unpacked from a JAR file after an initial call to the login page. Thus, a
single request to the login page is required before an attacker can
successfully exploit the vulnerability.
Vendor Response:
The fix for this security vulnerability is included in Oracle's January
2007 Critical Patch Update. The Critical Patch Update advisory, which
lists the versions affected and contains links to more information and
patches, is available at:

Recommendation:
Follow your organization's testing procedures before applying patches or
workarounds. Symantec recommends that customers should apply Oracle's
update as soon as possible.
Oracle strongly recommends applying the Oracle Enterprise Manager patches
released with the January 2007 Critical Patch Update to all instances
affected by this problem.
