The command-line cron implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly interact with IP blocking, which might allow remote attackers to bypass intended IP address restrictions by leveraging a configuration in which IP blocking was disabled to restore cron functionality.
CVE-2011-4591 1 Moodle 1 Moodle 2026-06-16 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in the print_object function in lib/datalib.php in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3, when a developer debugging script is enabled, allows remote attackers to inject arbitrary web script or HTML via vectors involving object states.
CVE-2011-4590 1 Moodle 1 Moodle 2026-06-16 4.0 MEDIUM N/A
The web services implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly consider the maintenance-mode state and account attributes during login attempts, which allows remote authenticated users to bypass intended access restrictions by connecting to a webservice server.
CVE-2011-4589 1 Moodle 1 Moodle 2026-06-16 5.5 MEDIUM N/A
backup/moodle2/restore_stepslib.php in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not check for the moodle/course:changeidnumber privilege during handling of course ID numbers, which allows remote authenticated users to overwrite ID numbers via a restore action.
CVE-2011-4588 1 Moodle 1 Moodle 2026-06-16 5.0 MEDIUM N/A
The ip_in_range function in mnet/lib.php in MNET in Moodle 1.9.x before 1.9.15 uses an incorrect data type, which allows remote attackers to bypass intended IP address restrictions via an XMLRPC request.

lib/moodlelib.php in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 does not properly handle certain zero values in the password policy, which makes it easier for remote attackers to obtain access by leveraging the possible existence of user accounts that have unchangeable blank passwords.
CVE-2011-4586 1 Moodle 1 Moodle 2026-06-16 5.0 MEDIUM N/A
CRLF injection vulnerability in calendar/set.php in the Calendar subsystem in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.
CVE-2011-4585 1 Moodle 1 Moodle 2026-06-16 5.0 MEDIUM N/A
login/change_password.php in Moodle 1.9.x before 1.9.15 does not use https for the change-password form even if the httpslogin option is enabled, which allows remote attackers to obtain credentials by sniffing the network.
CVE-2011-4584 1 Moodle 1 Moodle 2026-06-16 4.0 MEDIUM N/A
The MNET authentication functionality in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote authenticated users to impersonate other user accounts by using the Login As feature in conjunction with a remote MNET single sign-on capability, as demonstrated by a Mahara site.
CVE-2011-4583 1 Moodle 1 Moodle 2026-06-16 6.5 MEDIUM N/A
Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 displays web service tokens associated with (1) disabled services and (2) users who no longer have authorization, which allows remote authenticated users to have an unspecified impact by reading these tokens.
CVE-2011-4582 1 Moodle 1 Moodle 2026-06-16 4.9 MEDIUM N/A
Open redirect vulnerability in the Calendar set page in Moodle 2.1.x before 2.1.3 allows remote authenticated users to redirect users to arbitrary web sites and conduct phishing attacks via a redirection URL.
CVE-2011-4581 1 Moodle 1 Moodle 2026-06-16 4.0 MEDIUM N/A
mod/wiki/pagelib.php in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 allows remote authenticated users to discover the username of a wiki creator by visiting the history and deletion user interface.
CVE-2011-4580 1 Redhat 1 Jboss Enterprise Portal Platform 2026-06-16 4.3 MEDIUM N/A
Multiple cross-site scripting (XSS) vulnerabilities in Red Hat JBoss Enterprise Portal Platform before 5.2.0 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2011-4579 2 Ffmpeg, Libav 2 Ffmpeg, Libav 2026-06-16 4.3 MEDIUM N/A
The svq1_decode_frame function in the SVQ1 decoder (svq1dec.c) in libavcodec in FFmpeg 0.5.x before 0.5.7, 0.6.x before 0.6.4, 0.7.x before 0.7.9, and 0.8.x before 0.8.8; and in Libav 0.5.x before 0.5.6, 0.6.x before 0.6.4, and 0.7.x before 0.7.3 allows remote attackers to cause a denial of service (memory corruption) via a crafted SVQ1 stream, related to "dimensions changed."
CVE-2011-4578 1 Tedfelix 1 Acpid2 2026-06-16 4.6 MEDIUM N/A
event.c in acpid (aka acpid2) before 2.0.11 does not have an appropriate umask setting during execution of event-handler scripts, which might allow local users to (1) perform write operations within directories created by a script, or (2) read files created by a script, via standard filesystem system calls.
CVE-2011-4577 1 Openssl 1 Openssl 2026-06-16 4.3 MEDIUM N/A
OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers.
CVE-2011-4576 1 Openssl 1 Openssl 2026-06-16 5.0 MEDIUM N/A
The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer.
CVE-2011-4575 1 Redhat 3 Jboss Enterprise Application Platform, Jboss Enterprise Brms Platform, Jboss Enterprise Web Platform 2026-06-16 4.3 MEDIUM N/A

CVE-2011-4574 1 Polarssl 1 Polarssl 2026-06-16 7.5 HIGH 9.8 CRITICAL
PolarSSL versions prior to v1.1 use the HAVEGE random number generation algorithm. At its heart, this uses timing information based on the processor's high resolution timer (the RDTSC instruction). This instruction can be virtualized, and some virtual machine hosts have chosen to disable this instruction, returning 0s or predictable results.
