DESCRIPTION:
Multiple vulnerabilities and weaknesses have been reported in IBM
OmniFind Enterprise Edition, which can be exploited by malicious,
local users to gain escalated privileges and by malicious people to
conduct cross-site scripting, cross-site request forgery, and session
fixation attacks, disclose potentially sensitive information,
manipulate certain data, potentially cause a DoS (Denial of Service),
and compromise a vulnerable system.

1) Input passed to the "command" parameter in ESAdmin/collection.do
is not properly sanitised before being returned to the user. This can
be exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

2) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. create an arbitrary user with
administrative privileges if a logged-in administrative user visits a
malicious web site.

3) An error in the handling of sessions can be exploited to hijack
another user's session by tricking the user into logging in after
following a specially crafted link.

4) A boundary error in the
"Java_com_ibm_es_oss_CryptionNative_ESEncrypt()" function
(/opt/IBM/es/lib/libffq.cryptionjni.so) can be exploited to cause a
stack-based buffer overflow via an overly long "password" parameter
submitted to the administrative interface.

Successful exploitation may allow execution of arbitrary code in the
user context of the interface (by default the root user).

5) The "/opt/IBM/es/bin/esRunCommand" setuid program runs commands
supplied as an argument and can be exploited to execute arbitrary
shell commands with the privileges of the root user.

6) The "/opt/IBM/es/bin/estaskwrapper" setuid program incorrectly
runs the "estasklight" command and can be exploited to gain escalated
privileges e.g. by setting the ES_LIBRARY_PATH and PATH environment
variables to a directory containing a malicious binary and running
the program.

7) Lack of authentication in the ESSearchApplication/palette.do
script can be exploited to change the server's configuration.

8) A weakness in the Web Crawler agent when indexing a web page can
be exploited to consume server resources potentially causing a DoS.

9) Two weaknesses related to the configuration page and insecure
setting of a cookie path may lead to disclosure of sensitive
information via other vulnerabilities e.g. cross-site scripting
attacks.

The vulnerabilities and weaknesses are reported in version 8.5 and
9.1. Other versions may also be affected.

SOLUTION:
Reportedly patches have been released. Contact the vendor for further
information.
