Product Link: http://www.shoutcast.com/download ====================================================================== 4) Description of Vulnerability Secunia Research has discovered a vulnerability in SHOUTcast DNAS, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error when receiving data from a relay master server. This can be exploited to overflow a static buffer by tricking a SHOUTcast admin into setting up a server to act as relay for a malicious server. Successful exploitation allows to e.g. overwrite the password of the web administration interface. ====================================================================== 5) Solution Relay trusted servers only. ====================================================================== 6) Time Table 09/01/2009 - Vendor notified. 04/02/2009 - Requested status update from vendor. 25/02/2009 - 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 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.
