r0t has reported some vulnerabilities in Leadhound, which can be exploited by malicious people to conduct SQL injection and cross-site scripting attacks.
1) Input passed to the "banner" and "offset" parameters in agent_links.pl, to the "offset" parameter in agent_transactions.pl, agent_subaffiliates.pl and agent_summary.pl, to the "camp_id" parameter in agent_subaffiliates.pl and agent_camp_det.pl, and to the "agent_id" parameter in agent_commission_statement.pl isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed to the "login", "logged", "camp_id","banner","offset","date","dates", and "page" parameters in various scripts e.g. agent_affil.pl, agent_help.pl, agent_faq.pl, and modify_agent.pl, isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerabilities have been reported in the latest version.
Solution: Edit the source code to ensure that input is properly sanitised.
