Description:
Luigi Auriemma has discovered some vulnerabilities in Now SMS/MMS Gateway, which can be exploited by malicious people to compromise a vulnerable system.
1) A boundary error in the web interface when processing HTTP requests can be exploited to cause a stack-based buffer overflow via an HTTP request with an overly long "Authorization" header string.
Successful exploitation allows execution of arbitrary code.
2) A boundary error in the SMPP server when processing SMPP packets can be exploited to cause a stack-based buffer overflow via a specially crafted SMPP packet.
Successful exploitation allows execution of arbitrary code but requires that the SMPP server is enabled and a specific port is set.
The vulnerabilities are confirmed in version 2007.06.27. Prior versions may also be affected.
Solution:
Update to version 2008.02.22.
