Cross-site scripting (XSS) vulnerability in Moodle before 1.6.8, 1.7 before 1.7.6, 1.8 before 1.8.7, and 1.9 before 1.9.3 allows remote attackers to inject arbitrary web script or HTML via a Wiki page name (aka page title).

The _bad_protocol_once function in phpgwapi/inc/class.kses.inc.php in KSES, as used in eGroupWare before 1.4.003, Moodle before 1.8.5, and other products, allows remote attackers to bypass HTML filtering and conduct cross-site scripting (XSS) attacks via a string containing crafted URL protocols.

Cross-site scripting (XSS) vulnerability in install.php for Moodle 1.8.3, and possibly other versions before 1.8.4, allows remote attackers to inject arbitrary web script or HTML via the dbname parameter. NOTE: this issue only exists until the installation is complete.

Moodle 1.5.2 and earlier stores sensitive information under the web root with insufficient access control, and provides directory listings, which allows remote attackers to obtain user names, password hashes, and other sensitive information via a direct request for session (sess_*) files in moodledata/sessions/.

The Database module in Moodle before 1.6.2 does not properly handle uploaded files, which has unspecified impact and remote attack vectors.

Moodle before 1.6.2 does not properly validate the module instance id when creating a course module object, which has unspecified impact and remote attack vectors.

lib/setup.php in Moodle before 1.6.2 sets the error reporting level to 7 to display E_WARNING messages to users even if debugging is disabled, which might allow remote authenticated users to obtain sensitive information by triggering the messages.

help.php in Moodle before 1.6.2 does not check the existence of certain help files before including them, which might allow remote authenticated users to obtain the path in an error message.

backup/backup_scheduled.php in Moodle before 1.6.2 generates trace data with the full backup pathname even when debugging is disabled, which might allow attackers to obtain the pathname.

login/forgot_password.php in Moodle before 1.6.2 allows remote attackers to obtain sensitive information (e-mail addresses and Moodle account names) via a find action.

Multiple cross-site scripting (XSS) vulnerabilities in Moodle before 1.6.2 might allow remote attackers to inject arbitrary web script or HTML via (1) the choose parameter in files/index.php and (2) the sub parameter in doc/index.php.

Moodle before 1.6.2, when the configuration lacks (1) algebra or (2) tex filters, allows remote authenticated users to write LaTeX or MimeTeX output files to the top level of the dataroot directory via (a) filter/algebra/pix.php or (b) filter/tex/pix.php.

course/jumpto.php in Moodle before 1.6.2 does not validate the session key (sesskey) before providing content from arbitrary local URIs, which allows remote attackers to obtain sensitive information via the jump parameter.

Multiple cross-site scripting (XSS) vulnerabilities in Moodle 1.6.1 and earlier might allow remote attackers to inject arbitrary web script or HTML via unspecified parameters to (1) doc/index.php or (2) files/index.php.

SQL injection vulnerability in blog/edit.php in Moodle 1.6.1 and earlier allows remote attackers to execute arbitrary SQL commands via the format parameter as stored in the $blogEntry variable, which is not properly handled by the insert_record function, which calls _adodb_column_sql in the adodb layer (lib/adodb/adodb-lib.inc.php), which does not convert the data type to an int.

Moodle 1.6.1 and earlier allows remote attackers to obtain sensitive information via (1) help.php and (2) other unspecified vectors involving scheduled backups.

Multiple unknown vulnerabilities in Moodle before 1.5.1 have unknown impact and attack vectors.

Cross-site scripting (XSS) vulnerability in view.php in Moodle 1.4.2 and earlier allows remote attackers to inject arbitrary web script or HTML via the search parameter.

Directory traversal vulnerability in file.php in Moodle 1.4.2 and earlier allows remote attackers to read arbitrary session files for known session IDs via a .. (dot dot) in the file parameter.

SQL injection vulnerability in sql.php in the Glossary module in Moodle 1.4.1 and earlier allows remote attackers to modify SQL statements.
