References ========[ Overview ]============================================================ * System affected => [ 'Apache Axis <= 1.5' ] * Release date: => [ '24 June 2010' ] * Impact => [ 'Successful exploitation of this vulnerability may lead to remote administrative interface to accept a Session Hijacking' ] Axis2 [1] claims to be a Web Services / SOAP / WSDL engine, the successor to the widely used Apache Axis SOAP stack. Nowadays, there are two implementations of the Apache Axis2 Web services engine - Apache Axis2/Java and Apache Axis2/C. We have found a Session Fixation Vulnerability [2][3] in Apache Axis2. When successfully exploited, this vulnerability allows to fixate a Session Cookie in the browser of the victim, this way it's possible to perform session hijacking attacks. The chances of achieving success increases when the application is vulnerable to Cross Site Scripting or HTTP Header Injection. =====[ Detailed description ]=========================================== The vulnerability was found in the administrative interface of Axis2. By default, it is accessible at the path /axis2/axis2-admin. To exploit this flaw, we used a Cross Site Script in existing Axis2 (http://www.exploit-db.com/exploits/12721/). Code Snippet: http://example:8080/axis2/axis2-admin/engagingglobally?submit=%2bEngage 2b&modules= The above code when run on the victim's browser, fixates the session cookie sent by the attacker to it. =====[ Other contexts & Solutions ]===================================== As usual, we contacted the Apache Team [4]. Until this date there is no known fix to solve this flaw. ========[ Thanks ]===================================================== - Tempest Security Intelligence [5] - Pentest Team - Evandro Curvelo Hora - evandro *SPAM* tempest.com.br ========[ References ]================================================= [1] http://ws.apache.org/axis2/ [2] http://projects.webappsec.org/Session-Fixation [3] http://www.owasp.org/index.php/Testing_for_Session_Fixation_(OWASP-SM-003) [4] https://issues.apache.org/jira/browse/AXIS2-4739 [5] http://www.tempest.com.br
