The vulnerability is caused due to the application not properly sanitising the "name" attribute of the "file" element of metalink files before using it to download files. If a user is tricked into downloading from a specially crafted metalink file, this can be exploited to download files to directories outside of the intended download directory via directory traversal attacks. The vulnerability is confirmed in version 3.0.0.4 and 3.0.0.5. Other versions may also be affected. ====================================================================== 5) Solution Do not open untrusted metalink files. ====================================================================== 6) Time Table 30/04/2010 - Vendor notified. 12/05/2010 - Sent reminder to vendor. 19/05/2010 - Public disclosure. ====================================================================== 7) Credits Discovered by Stefan Cornelius, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has not yet assigned a CVE identifier for the vulnerability. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
