Web Application Security

Posted by  Drupal Security Team  on  October 15, 2014 at 4:02pm Advisory ID: DRUPAL-SA-CORE-2014-005 Project:  Drupal core Version: 7.x Date: 2014-Oct-15 Security risk:  25/25 ( Highly Critical ) AC:None/A:None/CI:All/II:All/E:Exploit/TD:All Vulnerability: SQL Injection Description Drupal 7 includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks. A vulnerability in this API allows an attacker to send specially crafted requests resulting in arbitrary SQL execution. Depending on the content of the requests this can lead to privilege escalation, arbitrary PHP execution, or other attacks. This vulnerability can be exploited by anonymous users. Update:  Multiple exploits have been reported in the wild following the release of this security advisory, and Drupal 7 sites which did not update soon after the advisory was released may be compromised. See this follow-...

It seems Google makes a new mistake by launching its new security key (2-step verification)  one of the steps is USB device .  The question  :how come can i plug USB into my mobile (I-Phone , I-Pad , Samsung Galaxy , ....) !  Do Google know the difficulties while you are holding a USB on your hand all the time .  so You can't access  your  account if it's not in your hands. or it's damaged ?  This solution is hopeless , I think it's designed for small audience. As someone says : Can you convince the Bank Manager while you are putting the USB Device into the bank PC, that you are securing your PC , not stealing the bank data, or not transferring amounts of money to other account . or what else .  You know , This way is not quietly good , If I have many accounts on Google and other websites ,I need many  USB devices to verify myself.  That's of course , not good at all.

Fake Data (Honey Data) By using honey data , it could help to identify attacks that are not triggered by error messages.  Honey data is data (e.g. Passwords, Credit card numbers,…) in tables which is never used by the application (Fake Ones). If someone from anywhere is accessing this kind of data , alert will be raised. Creation a table or tables containing unused data with juicy names (e.g. PASSWORD, CREDITCARD, SALARY).   Such interesting data is often the target of attackers.    During the attack, attackers are often accessing the view ALL_TAB_COLUMNS (Oracle) or INFORMATION_SCHEMA.COLUMNS (MySQL) to get the column names of interesting data.

When doing Audit on any table on the the database , the default auditing is DB. SQL > show parameters audit_trail NAME                                 TYPE        VALUE ------------------------------------ ----------- ------------------------------ audit_trail                          string      DB in this case , when you do audit on some table. SQL> audit all on scott.emp by access; Audit succeeded SQL> update emp set sal=sal*0.95 where job='MANAGER'; 3 rows updated. if you want to know the statement made these changes, you will receive nothing on the sql_text field while you are selecting the audit_trial table.

Heartbleed , what and how ?  Heartbleed is a bug in software commonly used to encrypt sensitive data between Web servers and Web browsers. The bug allows anyone on the Internet to compromise secret keys that Web servers use to encrypt traffic, which allows attackers to eavesdrop on all communication between the Web server and its users – even communication that was encrypted and supposed to be private. The Heartbleed vulnerability in OpenSSL has sent just about everyone who uses the Web for fun or profit gibbering madly in search of a solution, creating fertile ground for spammers, scammers and marketing types. The OpenSSL Software Project has issued a fix , and recommends upgrading immediately to OpenSSL 1.0.1g, or to recompile OpenSSL and disable the Heartbeat functionality that caused the vulnerability. "Be skeptical of unsolicited advice, especially advice that warns of dire consequences for inaction," warned Easy Solutions' Ingevaldson. ...
