CERT Advisory CA-2001-29 Oracle9iAS Web Cache vulnerable to buffer overflow
Original release date: October 25, 2001
Last revised: --
Source: CERT/CC
A complete revision history can be found at the end of this file.
Systems Affected
Systems running:
* Oracle9iAS Web Cache
Overview
A remotely exploitable buffer overflow in the Oracle9iAS Web Cache
allows intruders to execute arbitrary code or disrupt the normal
operation of Web Cache.
I. Description
Defcom Labs has discovered a remotely exploitable buffer overflow
vulnerability in the Oracle9iAS Web Cache (on all platforms) that
allows intruders to either execute arbitrary code with the
privileges of the Web Cache process, or disrupt the normal
operation of Web Cache. The Oracle9iAS Web Cache provides four web
services that are all vulnerable and enabled by default when the
software is installed. For more information about these web
services, please see the Oracle9iAS Web Cache Administration and
Deployment Guide (registration required). These services and the
associated ports they listen on are listed below:
* 1100/tcp (incoming web cache proxy)
* 4000/tcp (administrative interface)
* 4001/tcp (web XML invalidation port)
* 4002/tcp (statistics port)
Additional information regarding this vulnerability is available at
http://otn.oracle.com/deploy/security/pdf/webcache.pdf
http://www.securityfocus.com/archive/1/3BCEE434.F597D815@defcom.com
II. Impact
An intruder can execute arbitrary code with the privileges of the
web cache process or disrupt the normal operation of Web Cache.
Additionally, an intruder might be able to intercept and/or modify
sensitive data such as credentials and other types of sensitive
information passing through the host running Web Cache. Finally, an
intruder may be able to gain access to other systems by using Web
Cache as an entry point into the network or by leveraging an
existing trust relationship between Web Cache and another system.
III. Solution
Install a patch from Oracle. More information is available in
Appendix A.
