Firebird Database < 'fbserver.exe' Stack Overflow

Medium Nessus Network Monitor Plugin ID 4238


The remote host is vulnerable to a buffer overflow.


The remote host appears to be running a Firebird database server. This version of Firebird is vulnerable to a stack overflow when processing specially malformed requests. An attacker exploiting this flaw would only need the ability to send malformed packets to the fbserver.exe process which listens on TCP port 3050 by default. Successful exploitation would result in the attacker executing arbitrary code.


Upgrade to version or higher.
