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 [ davidl@ngssoftware.com ] 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.
