TITLE:

SECUNIA ADVISORY ID:
SA16108

VERIFY ADVISORY:
http://secunia.com/advisories/16108/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Sybase EAServer 4.x
http://secunia.com/product/367/
Sybase EAServer 5.x
http://secunia.com/product/5398/

DESCRIPTION:
SPI Dynamics has reported a vulnerability in Sybase EAServer, which
can be exploited by malicious users to compromise a vulnerable
system.

The vulnerability is caused due to a boundary error and can be
exploited to cause a stack-based buffer overflow by passing an overly
large javascript parameter to TreeAction.do in "/WebConsole/".

Successful exploitation allows execution of arbitrary code with the
privileges of the jagsrv.exe process, but requires that the user is
authenticated to "/WebConsole/".

SOLUTION:
Apply EBF (see vendor advisory for details).

PROVIDED AND/OR DISCOVERED BY:
David Dewey, SPI Dynamics.
