Citadel SMTP makeuserkey Function RCPT TO Command Remote Overflow

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

The remote mail server is prone to a buffer overflow attack.

Description :

The remote server is running Citadel, an open source solution for
email and collaboration.

According to its version, the installation of Citadel on the remote
host uses insufficient bounds-checking in its SMTP service during
memory-copy operations when processing input to the RCPT TO command.
An unauthenticated, remote attacker may be able to leverage this issue
to cause a stack-based buffer overflow, resulting in a crash of the
affected service or even execution of arbitrary code.

Solution :

Upgrade to Citadel version 7.11 or later.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.2
(CVSS2#E:F/RL:OF/RC:C)
