Description:
The CIDER Project's SHADOW intrusion detection utility is vulnerable to
CGI implementation flaws that allow a remote attacker to run arbitrary
commands on the analyzer. The problem occurs due to insufficient
character verification of sent variables. For multiple CGI scripts, an
attacker can send a specially crafted URL and execute commands with
the privileges of the running server.  

Technical Recommendation:
By design, the analyzer web interface should only be reachable through
an internal network and with password authentication. Since the
possibility remains that an attacker can reach the analyzer, disable
network access to the web interface and only view the web pages
locally.
