Title: ATutor 2.0.2 Multiple Remote Vulnerabilities (SQLi/XSS/PD)
Advisory ID: ZSL-2011-5036
Type: Remote
Impact: Exposure of System Information, Exposure of Sensitive Information, Manipulation of Data, Cross-Site Scripting
Risk: (3/5)
Release Date: 06.08.2011
The XSS issue is triggered when input passed via the 'search_friends_HASH' POST parameter, where HASH is the value generated by the 'rand_key' parameter, to the '/mods/_standard/social/index_public.php' script is not properly sanitised before being returned to the user.
The PD issues can be triggered by the cookie variable 'ATutorID' when setting random value or none in various scripts.
The SQLi issue can be triggered by 'p_course', 'name' and 'value' parameters in '/mods/_standard/social/set_prefs.php' script.
Theese issues can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site, displaying the full installation path in an error report and to manipulate SQL queries by injecting arbitrary SQL code.
