NGSSoftware Insight Security Research Advisory

Name: Multiple Password Exposures Flaws
Systems Affected: All versions of Informix
Severity: High
Vendor URL: http://www.ibm.com/
Author: David Litchfield [ [email protected] ]
Date of Public Advisory: 2nd August 2006
Advisory number: #NISR02082006E
CVEID: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3858
Advisory URL: http://www.ngssoftware.com/research/

Description


Informix Dynamic Server is a database developed by IBM. During a security
assessment of Informix multiple password exposure flaws were discovered.

Details


When a user logs on to an Informix server their cleartext password can be
found in a shared memory section. On Windows "everyone" can open the section
and read the contents and thus gain access to the passwords for every logged
on user. On both Linux and Windows, in the event of a crash the share memory
is dumped in a log file which is world readable.

Fix Information


IBM was alerted to these flaws on the 10th January 2005. Patches have now
been made available.

NGSSQuirreL for Informix, an advanced vulnerability assessment scanner
designed specifically for Informix, can be used to accurately determine
whether your servers are vulnerable to this flaw. More information about
NGSSQuirreL for Informix can be found here
