Description:
Some vulnerabilities have been reported in Dokeos, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to conduct SQL injection and cross-site scripting attacks.
1) Input passed to the "id" parameter in whoisonline.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires valid user credentials.
2) Input passed to the "Referer" and "User-Agent" HTTP headers in e.g. index.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
3) Input passed to the "courseCode" parameter in main/calendar/myagenda.php and the "message" parameter in main/admin/session_list.php is not properly sanitised before being returned to a 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) Input passed to the "category" parameter in main/admin/course_category.php is not properly sanitised before being used in SQL queries or returned to a user. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code or execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires valid administrator credentials.
The vulnerabilities are reported in version 1.8.4. Other versions may also be affected.
Note: Other, disputed vulnerabilities were also reported. Additionally, the update contains patches, which may fix other potentially security relevant issues.
