PyAMF 0.7.2 XXE Injection
Posted Dec 17, 2015
Authored by Nicolas Gregoire, Open Source CERT

PyAMF suffers from insufficient AMF input payload sanitization which results in the XML parser not preventing the processing of XML external entities (XXE). A specially crafted AMF payload, containing malicious references to XML external entities, can be used to trigger denial of service (DoS) conditions or arbitrarily return the contents of files that are accessible with the running application privileges. Versions 0.7.2 and below are affected.

Xalan-Java 2.7.0 Insufficient Secure Processing
Posted Mar 25, 2014
Authored by Andrea Barisani, Nicolas Gregoire, Open Source CERT

The Xalan-Java library is a popular XSLT processor from the Apache Software Foundation. The library implements the Java API for XML Processing (JAXP) which supports a secure processing feature for interpretive and XSLCT processors. The intent of this feature is to limit XSLT/XML processing behaviours to "make the XSLT processor behave in a secure fashion". It has been discovered that the secure processing features suffers from several limitations that undermine its purpose. Versions 2.7.0 and above are affected.

HP StorageWorks P4000 Virtual SAN Appliance Command Execution
Posted May 22, 2012
Authored by Nicolas Gregoire, sinn3r | Site metasploit.com

This Metasploit module exploits a vulnerability found in HP's StorageWorks P4000 VSA on versions prior to 9.5. By using a default account credential, it is possible to inject arbitrary commands as part of a ping request via port 13838.

Squiggle 1.7 SVG Browser Java Code Execution
Posted May 18, 2012
Authored by Nicolas Gregoire, sinn3r, juan vazquez | Site metasploit.com

This Metasploit module abuses the SVG support to execute Java Code in the Squiggle Browser included in the Batik framework 1.7 through a crafted svg file referencing a jar file. In order to gain arbitrary code execution, the browser must meet the following conditions: (1) It must support at least SVG version 1.1 or newer, (2) It must support Java code and (3) The "Enforce secure scripting" check must be disabled. The module has been tested against Windows and Linux platforms.

Liferay XSL Command Execution
Posted Apr 7, 2012
Authored by Nicolas Gregoire, Spencer McIntyre | Site metasploit.com

This Metasploit module exploits a vulnerability in the XSL parser of the XSL Content Portlet. When Tomcat is present, arbitrary code can be executed via java calls in the data fed to the Xalan XSLT processor. If XSLPAGE is defined, the user must have rights to change the content of that page (to add a new XSL portlet), otherwise it can be left blank and a new one will be created. The second method however, requires administrative privileges.

Apple Safari Webkit libxslt Arbitrary File Creation
Posted Oct 18, 2011
Authored by Nicolas Gregoire | Site metasploit.com

This Metasploit module exploits a file creation vulnerability in the Webkit rendering engine. It is possible to redirect the output of a XSLT transformation to an arbitrary file. The content of the created file must be ASCII or UTF-8. The destination path can be relative or absolute. This Metasploit module has been tested on Safari and Maxthon. Code execution can be achieved by first uploading the payload to the remote machine in VBS format, and then upload a MOF file, which enables Windows Management Instrumentation service to execute the VBS.
