Cross-site scripting (XSS) vulnerability in the phpCAS client library before 1.1.0, as used in Moodle 1.8.x before 1.8.12 and 1.9.x before 1.9.8, allows remote attackers to inject arbitrary web script or HTML via a crafted URL, which is not properly handled in an error message.
Cross-site scripting (XSS) vulnerability in the fix_non_standard_entities function in the KSES HTML text cleaning library (weblib.php), as used in Moodle 1.8.x before 1.8.12 and 1.9.x before 1.9.8, allows remote attackers to inject arbitrary web script or HTML via crafted HTML entities.
Multiple cross-site request forgery (CSRF) vulnerabilities in Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 allow remote attackers to hijack the authentication of unspecified victims via unknown vectors.
The LAMS module (mod/lams) for Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 stores the (1) username, (2) firstname, and (3) lastname fields within the user table, which allows attackers to obtain user account information via unknown vectors.
mod/glossary/showentry.php in the Glossary module for Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 does not properly perform access control, which allows attackers to read unauthorized Glossary entries via unknown vectors.
Multiple unspecified authentication plugins in Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 store the MD5 hashes for passwords in the user table, even when the cached hashes are not used by the plugin, which might make it easier for attackers to obtain credentials via unspecified vectors.
mnet/lib.php in Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7, when MNET services are enabled, does not properly check permissions, which allows remote authenticated servers to execute arbitrary MNET functions.
login/index_form.html in Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 links to an index page on the HTTP port even when the page is served from an HTTPS port, which might cause login credentials to be sent in cleartext, even when SSL is intended, and allows remote attackers to obtain these credentials by sniffing.
Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 stores (1) password hashes and (2) unspecified "secrets" in backup files, which might allow attackers to obtain sensitive information.
Moodle 1.8 before 1.8.11 and 1.9 before 1.9.7 does not use a random password salt in config.php, which makes it easier for attackers to conduct brute-force password guessing attacks.
