IBM solidDB 'solid.exe' Lets Remote Users Bypass Authentication
SecurityTracker Alert ID:  1025283
SecurityTracker URL:
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Apr 4 2011
Impact:   User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 4.5.180, 6.0.1066, 6.1.20, 6.3 Fix Pack 6, 6.5 Fix Pack 2; and prior versions
Description:   A vulnerability was reported in IBM solidDB. A remote user can access the target database.

A remote user can send a specially crafted length value to the 'solid.exe' process on TCP ports ports 1315, 1964, or 2315 to cause the process to only evaluate the first several bytes of the password hash instead of the full length of the password hash. A remote user can exploit this to gain access to the target databse.

The vendor was notified on September 29, 2010.

Tenable Network Security reported this vulnerability via TippingPoint's Zero Day Initiative.

Impact:   A remote user can access the target database.
Solution:   The vendor has issued a fix (4.5.181, 6.0.1067, 6.3.47 (FP7), (FP3).

The vendor's advisory is available at:

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of IBM solidDB. Authentication is not required
to exploit this vulnerability. 

The specific flaw exists within the solid.exe process which listens by
default on TCP ports 1315, 1964 and 2315. The authentication protocol
allows a remote attacker to specify the length of a password hash. By
specifying a minimum length the attacker can force the process to
validate only the first several bytes of the password hash. This can be
abused to bypass authentication to the database.

-- Vendor Response:
IBM has issued an update to correct this vulnerability. More
