-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ZDI-12-039 : Oracle Java Web Start java-vm-args Command Argument Injection Remote Code Execution http://www.zerodayinitiative.com/advisories/ZDI-12-039 February 22, 2012 - -- CVE ID: - -- CVSS: 9, AV:N/AC:L/Au:N/C:P/I:P/A:C - -- Affected Vendors: Oracle - -- Affected Products: Oracle Java Runtime - -- TippingPoint(TM) IPS Customer Protection: TippingPoint IPS customers have been protected against this vulnerability by Digital Vaccine protection filter ID 12107. For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Oracle Java. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the way Java Webstart handles the 'java-vm-args' parameter in the j2se tag within a jnlp file. Due to insufficient sanitation it is possible to add additional double quotes to the commandline argument string used to start a new java process. This can lead to remote code execution under the rights of the current user. - -- Vendor Response: Oracle has issued an update to correct this vulnerability. More details can be found at: http://www.oracle.com/technetwork/topics/security/javacpufeb2012-366318.html - -- Disclosure Timeline: 2011-11-21 - Vulnerability reported to vendor 2012-02-22 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.
