Vulnerability Information

Severity: Critical
Vulnerability Published: 2006-08-29
Patch Published: 2006-08-29
CVE [?]: CVE-2006-4305
CPE [?]: N/A

Synopsis

The remote web server is prone to a buffer overflow attack.

Description

The remote host is running SAP DB or MaxDB, a SAP-certified open- source database supporting OLTP and OLAP.

According to its version, the Web DBM component of MaxDB on the remote host reportedly contains a buffer overflow that can be triggered by an HTTP request containing a long database name. An unauthenticated remote attacker may be able to exploit this flaw to execute arbitrary code on the affected host subject to the privileges of the 'wahttp' process.

Note that on Windows the 'wahttp' process runs with 'SYSTEM' privileges so a successful attack may result in a complete compromise of the affected system.

Solution

Upgrade to Web DBM version 7.6.00.31 or later as that is reported to fix the issue.

Public Exploits

Target Network Port(s): 9999
Target Asset(s): Services/www
Exploit Available: True (Metasploit Framework, Exploit-DB)
Exploit Ease: No exploit is required

Here's the list of publicly known exploits and PoCs for verifying the SAP DB / MaxDB WebDBM Client Database Name Remote Overflow vulnerability:

Metasploit: exploit/windows/http/maxdb_webdbm_database
[MaxDB WebDBM Database Parameter Overflow]
Exploit-DB: exploits/windows/remote/16765.rb
[EDB-16765: MaxDB WebDBM - 'Database' Remote Overflow (Metasploit)]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.
