A weakness and some vulnerabilities have been discovered in evalSMSI, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to conduct SQL injection, cross-site scripting attacks, and disclose sensitive information.
1) Input passed to the "query" parameter in ajax.php (when "action" is set to "question") is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
2) Input passed while writing comments to assess.php (when "action" is set to "continue_assess") is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.
3) Input passed to the "return" parameter in ajax.php is not 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.
4) The weakness is caused due to the application storing password in the database in clear text.
The vulnerabilities are confirmed in version 2.1.03.
Solution: Vulnerabilities #1 and #3 are fixed in version 2.2.00. Grant only trusted users access to the application.
