eSO Security Advisory: 2408
Discovery Date: April 3, 2000
ID: eSO:2408
Title: CIDER SHADOW CGI arbitrary command execution
                        vulnerabilities
Impact: Remote attackers can execute commands with the
                        privileges of the running web server process
Affected Technology: CIDER SHADOW 1.5, 1.6
Vendor Status: Vendor informed
Discovered By: Kevin Kotas of the eSecurityOnline Research
                        and Development Team
CVE Reference: CAN-2002-0091

Advisory Location:
http://www.eSecurityOnline.com/advisories/eSO2408.asp

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.
