Multiple cross-site scripting (XSS) vulnerabilities in ATutor LMS version 2.2.

Multiple Cross-Site Scripting (XSS) issues were discovered in ATutor 2.2.2. The vulnerabilities exist due to insufficient filtration of user-supplied data passed to several pages (lang_code in themes/*/admin/system_preferences/language_edit.tmpl.php). An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Directory Traversal exists in ATutor before 2.2.2 via the icon parameter to /mods/_core/courses/users/create_course.php. The attacker can read an arbitrary file by visiting get_course_icon.php?id= after the traversal attack.

Cross-site request forgery (CSRF) vulnerability in install_modules.php in ATutor before 2.2.2 allows remote attackers to hijack the authentication of users for requests that upload arbitrary files and execute arbitrary PHP code via vectors involving a crafted zip file.

SQL injection vulnerability in include/lib/mysql_connect.inc.php in ATutor 2.2.1 allows remote attackers to execute arbitrary SQL commands via the searchFriends function to friends.inc.php.

ATutor versions 2.2.1 and earlier are vulnerable to a directory traversal and file extension check bypass in the Course component resulting in code execution. ATutor versions 2.2.1 and earlier are vulnerable to a directory traversal vulnerability in the Course Icon component resulting in information disclosure.

ATutor versions 2.2.1 and earlier are vulnerable to an incorrect access control check vulnerability in the Social Application component resulting in privilege escalation. ATutor versions 2.2.1 and earlier are vulnerable to an incorrect access control check vulnerability in the Module component resulting in privilege escalation. ATutor versions 2.2.1 and earlier are vulnerable to a incorrect access control check vulnerability in the Alternative Content component resulting in privilege escalation.

ATutor version 2.2.1 and earlier are vulnerable to a SQL injection in the Assignment Dropbox, BasicLTI, Blog Post, Blog, Group Course Email, Course Alumni, Course Enrolment, Group Membership, Course unenrolment, Course Enrolment List Search, Glossary, Social Group Member Search, Social Friend Search, Social Group Search, File Comment, Gradebook Test Title, User Group Membership, Inbox/Sent Items, Sent Messages, Links, Photo Album, Poll, Social Application, Social Profile, Test, Content Menu, Auto-Login, and Gradebook components resulting in information disclosure, database modification, or potential code execution.

Multiple eval injection vulnerabilities in mods/_standard/gradebook/edit_marks.php in ATutor 2.2 and earlier allow remote authenticated users with the AT_PRIV_GRADEBOOK privilege to execute arbitrary PHP code via the (1) asc or (2) desc parameter.

Cross-site scripting (XSS) vulnerability in mods/_standard/forums/admin/forum_add.php in ATutor 2.1.1 allows remote authenticated administrators to inject arbitrary web script or HTML via the title parameter in an add_forum action. NOTE: the original disclosure also reported issues that may not cross privilege boundaries.

Unrestricted file upload vulnerability in mods/_core/properties/lib/course.inc.php in ATutor before 2.2 patch 6 allows remote authenticated users to execute arbitrary PHP code by uploading a file with a PHP extension as a customicon for a new course, then accessing it via a direct request to the file in content/.

Multiple cross-site scripting (XSS) vulnerabilities in ATutor before 2.1 allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) themes/default/tile_search/index.tmpl.php, (2) login.php, (3) search.php, (4) password_reminder.php, (5) login.php/jscripts/infusion, (6) login.php/mods/_standard/flowplayer, (7) browse.php/jscripts/infusion/framework/fss, (8) registration.php/themes/default/ie_styles.css, (9) about.php, or (10) themes/default/social/basic_profile.tmpl.php.

Multiple cross-site scripting (XSS) vulnerabilities in ATutor 1.6.4 allow remote authenticated users, with Instructor privileges, to inject arbitrary web script or HTML via the (1) Question and (2) Choice fields in tools/polls/add.php, the (3) Type and (4) Title fields in tools/groups/create_manual.php, and the (5) Title field in assignments/add_assignment.php. NOTE: some of these details are obtained from third party information.

ATutor 2.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by users/tool_settings.inc.php and certain other files.

A Cross-site scripting (XSS) vulnerability in the function encrypt_password() in login.tmpl.php in ATutor 2.2.1 allows remote attackers to inject arbitrary web script or HTML via the token parameter.

An Access Control vulnerability exists in ATutor 2.2.4 in password_reminder.php when the g, id, h, form_password_hidden, and form_change HTTP POST parameters are set.

A reflected cross site scripting (XSS) vulnerability in the /header.tmpl.php component of ATutor 2.2.4 allows attackers to execute arbitrary web scripts or HTML via a crafted payload.

A stored-self XSS exists in ATutor through v2.2.4, allowing an attacker to execute HTML or JavaScript code in a vulnerable Real Name field to /mods/_core/users/admins/my_edit.php.

In ATutor 2.2.4, an unauthenticated attacker can change the application settings and force it to use his crafted database, which allows him to gain access to the application. Next, he can change the directory that the application uploads files to, which allows him to achieve remote code execution. This occurs because install/include/header.php does not restrict certain changes (to db_host, db_login, db_password, and content_dir) within install/include/step5.php.

ATutor through 2.2.4 is vulnerable to arbitrary file uploads via the mods/_core/backups/upload.php (aka backup) component. This may result in remote command execution. An attacker can use the instructor account to fully compromise the system using a crafted backup ZIP archive. This will allow for PHP files to be written to the web root, and for code to execute on the remote server.
