TITLE:
Now SMS/MMS Gateway HTTP/SMPP Handling Buffer Overflows

SECUNIA ADVISORY ID:
SA29003

VERIFY ADVISORY:
http://secunia.com/advisories/29003/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Now SMS/MMS Gateway 2007.x
http://secunia.com/product/17663/

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. Other
versions may also be affected.

SOLUTION:
Restrict network access to the services.

PROVIDED AND/OR DISCOVERED BY:
