Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3181)
The vulnerability allows a remote #AU# to manipulate data.
files/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 does not consider the moodle/user:manageownfiles capability before approving a private-file upload, which allows remote authenticated users to bypass intended file-management restrictions by using web services to perform uploads after this capability has been revoked.
2) Information disclosure (CVE-ID: CVE-2015-3180)
The vulnerability allows a remote #AU# to gain access to sensitive information.
lib/navigationlib.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 allows remote authenticated users to obtain sensitive course-structure information by leveraging access to a student account with a suspended enrolment.
3) Cross-site scripting (CVE-ID: CVE-2015-3178)
Vulnerability allows a remote attacker to perform Cross-site scripting attacks.
An input validation error exists in the external_format_text function in lib/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6. A remote authenticated attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3179)
The vulnerability allows a remote #AU# to manipulate data.
login/confirm.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 allows remote authenticated users to bypass intended login restrictions by leveraging access to an unconfirmed suspended account.
5) Information disclosure (CVE-ID: CVE-2015-3176)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The account-confirmation feature in login/confirm.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 allows remote attackers to obtain sensitive full-name information by attempting to self-register.
6) Input validation error (CVE-ID: CVE-2015-3177)
The vulnerability allows a remote #AU# to gain access to sensitive information.
Moodle 2.8.x before 2.8.6 does not consider the tool/monitor:subscribe capability before entering subscriptions to site-wide event-monitor rules, which allows remote authenticated users to obtain sensitive information via a subscription request.
7) Cross-site scripting (CVE-ID: CVE-2015-3174)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. The vulnerability allows remote authenticated users to conduct cross-site scripting (XSS) attacks via crafted gradebook feedback during manual quiz grading.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
8) Input validation error (CVE-ID: CVE-2015-3175)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Multiple open redirect vulnerabilities in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via vectors involving an error page that links to a URL from an HTTP Referer header. <a href="http://cwe.mitre.org/data/definitions/601.html">CWE-601: URL Redirection to Untrusted Site ('Open Redirect')</a>
9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2015-3273)
The vulnerability allows a remote authenticated user to manipulate data.
mod/forum/post.php in Moodle 2.9.x before 2.9.1 does not consider the mod/forum:canposttomygroups capability before authorizing "Post a copy to all groups" actions, which allows remote authenticated users to bypass intended access restrictions by leveraging per-group authorization.
10) Input validation error (CVE-ID: CVE-2015-3272)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
Open redirect vulnerability in the clean_param function in lib/moodlelib.php in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via vectors involving an HTTP Referer header that has a substring match with a local URL. <a href="http://cwe.mitre.org/data/definitions/601.html">CWE-601: URL Redirection to Untrusted Site ('Open Redirect')</a>
11) Cross-site scripting (CVE-ID: CVE-2015-3275)
Vulnerability allows a remote attacker to perform XSS attacks.
The vulnerability is caused by an input validation error in the SCORM module in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1 when processing a crafted organization name to (1) mod/scorm/player.php or (2) mod/scorm/prereqs.php. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
12) Cross-site scripting (CVE-ID: CVE-2015-3274)
Vulnerability allows a remote attacker to perform XSS attacks.
The vulnerability is caused by an input validation error in the user_get_user_details function in user/lib.php in Moodle through 2.6.11, 2.7.x before 2.7.9, 2.8.x before 2.8.7, and 2.9.x before 2.9.1. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in victim's browser in security context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
