Computer Associates Content-Length Buffer Overflow in iGateway Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015526
SecurityTracker URL:  http://securitytracker.com/id/1015526
CVE Reference:   CVE-2005-3653   (Links to External Site)
Updated:  Jan 27 2006
Original Entry Date:  Jan 23 2006
Impact:   Execution of arbitrary code via network, Root access via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 4.0.050615 and prior versions
Description:   iDEFENSE reported a vulnerability in Computer Associates iGateway. A remote user can execute arbitrary code on the target system.

A remote user can send an HTTP request with a specially crafted, negative HTTP Content-Length value to the iGateway service on port 5250 on the target system to trigger a buffer overflow. By also supplying a specially crafted, large URI, arbitrary code can be executed on the target system. The code will run with System level privileges on Windows-based systems.

Several Computer Associates products include iGateway, including:

Computer Associates iTechnology iGateway Service Content-Length Buffer
Overflow Vulnerability

iDefense Security Advisory 01.23.06
http://www.idefense.com/intelligence/vulnerabilities/display.php?id=376
January 23, 2006

I. BACKGROUND

iTechnology is an integration technology which provides standard web
service interfaces to third-party products, exposing normalized
security event data and information in XML format.

II. DESCRIPTION

Remote exploitation of an input validation error in Computer Associates,
Inc.'s iTechnology allows remote attackers to execute arbitrary code.

The vulnerability specifically exists in the iGateway service that
listens on port 5250 for standard HTTP or SSL traffic. The iGateway
service fails to properly handle negative HTTP Content-Length values.
iGateway parses the negative content-length value from an HTTP request
and uses the value directly in a malloc() heap allocation call. By
supplying negative values, the heap allocation call will return a very
small buffer. Subsequent to the malloc() call, a memcpy of the supplied
URI into the allocated buffer can overflow into the heap. A remote
attacker can send a request with a very large URI and a negative
content-length to corrupt the heap and potentially execute arbitrary
code.

III. ANALYSIS

Successful exploitation of this vulnerability allows remote attackers to
execute arbitrary code with SYSTEM level permissions. The iTechnology
package is distributed with various Computer Associates eTrust brand
software. Any attacker who can reach port 5250 on an affected host can
attempt to exploit this vulnerability.

IV. DETECTION

iDefense has confirmed the existence of this vulnerability in Computer
Associates iTechnology iGateway 4.0. It is suspected all versions of the
iGateway package prior to and including 4.0.050615 are vulnerable.
