Secunia reports:
A vulnerability has been reported in Plans, which can be
exploited by malicious people to conduct SQL injection
attacks.
Input passed to the "evt_id" parameter in "plans.cgi"
isn't properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by
injecting arbitrary SQL code.
Successful exploitation requires that SQL database
support has been enabled in "plans_config.pl" (the default
setting is flat files).
Some vulnerabilities have been reported in Plans, which
can be exploited by malicious people to conduct cross-site
scripting attacks or gain knowledge of sensitive
information.
Input passed to various unspecified parameters is not
properly sanitised before being returned to users. This
can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of a vulnerable
site.
