1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4400)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote #AU# to manipulate data.
repository/repository_ajax.php in Moodle 2.2.x before 2.2.5 and 2.3.x before 2.3.2 allows remote authenticated users to bypass intended upload-size restrictions via a -1 value in the maxbytes field.
2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4401)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote #AU# to manipulate data.
Moodle 2.2.x before 2.2.5 and 2.3.x before 2.3.2 allows remote authenticated users to bypass intended capability restrictions and perform certain topic changes by leveraging course-editing capabilities.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4402)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote #AU# to read and manipulate data.
webservice/lib.php in Moodle 2.1.x before 2.1.8, 2.2.x before 2.2.5, and 2.3.x before 2.3.2 does not properly restrict the use of web-service tokens, which allows remote authenticated users to run arbitrary external-service functions via a token intended for only one service.
4) Information disclosure (CVE-ID: CVE-2012-4403)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
theme/yui_combo.php in Moodle 2.3.x before 2.3.2 does not properly construct error responses for the drag-and-drop script, which allows remote attackers to obtain the installation path by sending a request for a nonexistent resource and then reading the response.
5) Information disclosure (CVE-ID: CVE-2012-4407)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
lib/filelib.php in Moodle 2.1.x before 2.1.8, 2.2.x before 2.2.5, and 2.3.x before 2.3.2 does not properly check the publication state of blog files, which allows remote attackers to obtain sensitive information by reading a blog entry that references a non-public file.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-4408)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote #AU# to read and manipulate data.
course/reset.php in Moodle 2.1.x before 2.1.8, 2.2.x before 2.2.5, and 2.3.x before 2.3.2 checks an update capability instead of a reset capability, which allows remote authenticated users to bypass intended access restrictions via a reset operation.
