The remote host is running a version of the Gupta SQLBase server which is older than or equal to 8.1.0.
An error in the ‘Execute’ command makes it possible to trigger a buffer overflow by supplying more than 700 characters as the parameter. A remote, authenticated attacker, exploiting this flaw, can crash the affected service or potentially execute arbitrary code with SYSTEM privileges.
