    Advisory ID: SYMSA-2006-09
    Advisory Title: SAP-DB/MaxDB WebDBM remote buffer overflow
    Author: Oliver Karow / Oliver_Karow@symantec.com
    Release Date: 29-08-2006
    Application: SAP-DB/MaxDB 7.6.00.22 - WebDBM
    Platform: Windows/Unix
    Severity: Remotely exploitable/Local System Access
    Vendor status: Verified by vendor / Resolved in 7.6.00.31
    CVE Number: CVE-2006-4305
    Reference: http://www.securityfocus.com/bid/19660


Overview:

      A connection from a WebDBM Client to the DBM Server causes a
buffer overflow when the given database name is too large. This
can result in the execution of arbitrary code in the context of
the database server.


Details:
      SAP-DB/MaxDB is a heavy-duty, SAP-certified open source
database for OLTP and OLAP usage which offers high reliability,
availability, scalability and a very comprehensive feature set.
It is targeted for large mySAP Business Suite environments
and other applications that require maximum enterprise-level
database functionality and complements the MySQL database server.

      A remotely exploitable vulnerability exists in MaxDB's WebDBM.
Due to an input validation error, it is possible to execute
arbitrary code with the privileges of the 'wahttp' process by
sending a malformed HTTP request. Authentication is not required
for successful exploitation to occur.
	

Vendor Response:

The above vulnerability has been fixed in the latest release of
the product, MaxDB 7.6.00.31.

Licensed and evaluation versions of MaxDB are available for
download in the download section of www.mysql.com/maxdb:
http://dev.mysql.com/downloads/maxdb/7.6.00.html.

If there are any further questions about this statement, please
contact mysql-MaxDB support.

Please note that SAP customers receive their downloads via the
SAP Service Marketplace www.service.sap.com and must not use
downloads from the addresses above for their SAP solutions.

Recommendation:

	The vendor has released MaxDB 7.6.00.31 to address
this issue. Users should contact the vendor to obtain the
appropriate upgrade.

As a temporary workaround the SAP-DB WWW Service should either
be disabled or have access to it restricted using appropriate
network or client based access controls.
