Ansible Tower as shipped with Red Hat CloudForms Management Engine 5 is vulnerable to CRLF Injection. It was found that X-Forwarded-For header allows internal servers to deploy other systems (using callback).

Red Hat JBoss Operations Network 3.3.1 does not properly restrict access to certain APIs, which allows remote attackers to execute arbitrary Java methods via the (1) ServerInvokerServlet or (2) SchedulerService or (3) cause a denial of service (disk consumption) via the ContentManager.

spacewalk-backend in Red Hat Network Satellite 5.4 on Red Hat Enterprise Linux 6 does not properly authorize or authenticate uploads to the NULL organization when mod_wsgi is used, which allows remote attackers to cause a denial of service (/var partition disk consumption and failed updates) via a large number of package uploads.

The dpkg-source command in Debian dpkg before 1.16.16 and 1.17.x before 1.17.25 allows remote attackers to bypass signature verification via a crafted Debian source control file (.dsc).

An issue was discovered in the auth component in Dovecot 2.2 and 2.3 before 2.3.20. When two passdb configuration entries exist with the same driver and args settings, incorrect username_filter and mechanism settings can be applied to passdb definitions. These incorrectly applied settings can lead to an unintended security configuration and can permit privilege escalation in certain configurations. The documentation does not advise against the use of passdb definitions that have the same driver and args settings. One such configuration would be where an administrator wishes to use the same PAM configuration or passwd file for both normal and master users but use the username_filter setting to restrict which of the users is able to be a master user.

The OpenSSH server, as used in Fedora and Red Hat Enterprise Linux 7 and when running in a Kerberos environment, allows remote authenticated users to log in as another user when they are listed in the .k5users file of that user, which might bypass intended authentication requirements that would force a local login.

Red Hat JBoss Operations Network (JON) 3.0.x before 3.0.1, 2.4.2, and earlier, when LDAP authentication is enabled and the LDAP bind account credentials are invalid, allows remote attackers to login to LDAP-based accounts via an arbitrary password in a login request.

MongoDB on Red Hat Satellite 6 allows local users to bypass authentication by logging in with an empty password and delete information which can cause a Denial of Service.

Red Hat Satellite 6 allows local users to access mongod and delete pulp_database.

It was found that foreman, versions 1.x.x before 1.15.6, in Satellite 6 did not properly enforce access controls on certain resources. An attacker with access to the API and knowledge of the resource name can access resources in other organizations.

The Linux-PAM package before 1.5.2-6.1 for openSUSE Tumbleweed allows authentication bypass for SSH logins. The pam_access.so module doesn't correctly restrict login if a user tries to connect from an IP address that is not resolvable via DNS. In such conditions, a user with denied access to a machine can still get access. NOTE: the relevance of this issue is largely limited to openSUSE Tumbleweed and openSUSE Factory; it does not affect Linux-PAM upstream.

The Red Hat gluster-swift package, as used in Red Hat Gluster Storage (formerly Red Hat Storage Server), allows remote authenticated users to bypass the max_meta_count constraint via multiple crafted requests which exceed the limit when combined.

Red Hat JBoss Operations Network (JON) before 2.4.2 and 3.0.x before 3.0.1 allows remote attackers to hijack agent sessions via an agent registration request without a security token.

Improper access control for some Intel(R) PROSet/Wireless WiFi and Killer(TM) WiFi software may allow a privileged user to potentially enable escalation of privilege via local access.

A Improper Access Control vulnerability in the systemd service of cana in openSUSE Backports SLE-15-SP3, openSUSE Backports SLE-15-SP4 allows local users to hijack the UNIX domain socket This issue affects: openSUSE Backports SLE-15-SP3 canna versions prior to canna-3.7p3-bp153.2.3.1. openSUSE Backports SLE-15-SP4 canna versions prior to 3.7p3-bp154.3.3.1. openSUSE Factory was also affected. Instead of fixing the package it was deleted there.

Supported versions that are affected are Oracle Java SE: 7u331, 8u321, 11.0.14, 17.0.2, 18; Oracle GraalVM Enterprise Edition: 20.3.5, 21.3.1 and 22.0.0.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

A flaw was found in the CloudForms account configuration when using VMware. By default, a shared account is used that has privileged access to VMRC (VMWare Remote Console) functions that may not be appropriate for users of CloudForms (and thus this account). An attacker could use this vulnerability to view and make changes to settings in the VMRC and virtual machines controlled by it that they should not have access to.

The networkReloadIptablesRules function in network/bridge_driver.c in libvirt before 0.9.9 does not properly handle firewall rules on bridge networks when libvirtd is restarted, which might allow remote attackers to bypass intended access restrictions via a (1) DNS or (2) DHCP query.

A flaw was found in ovirt-engine 4.4.3 and earlier allowing an authenticated user to read other users' personal information, including name, email and public SSH key.

OpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials.

A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.

The authfile directive in the booth config file is ignored, preventing use of authentication in communications from node to node. As a result, nodes that do not have the correct authentication key are not prevented from communicating with other nodes in the cluster.

Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.

A flaw was found in keycloak in versions prior to 13.0.0. The client registration endpoint allows fetching information about PUBLIC clients (like client secret) without authentication which could be an issue if the same PUBLIC client changed to CONFIDENTIAL later. The highest threat from this vulnerability is to data confidentiality.

A flaw was found in Keycloak. The org.keycloak.authorization package may be vulnerable to circumventing required actions, allowing users to circumvent requirements such as setting up two-factor authentication.

Improper Authentication vulnerability in TLS origin validation of Apache Traffic Server allows an attacker to create a man in the middle attack. This issue affects Apache Traffic Server 8.0.0 to 8.1.0.

A Red Hat only CVE-2020-12352 regression issue was found in the way the Linux kernel's Bluetooth stack implementation handled the initialization of stack memory when handling certain AMP packets. This flaw allows a remote attacker in an adjacent range to leak small portions of stack memory on the system by sending specially crafted AMP packets. The highest threat from this vulnerability is to data confidentiality.

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.

After the initial setup process, some steps of setup.php file are reachable not only by super-administrators, but by unauthenticated users as well. Malicious actor can pass step checks and potentially change the configuration of Zabbix Frontend.

In SaltStack Salt through 3002, salt-netapi improperly validates eauth credentials and tokens. A user can bypass authentication and invoke Salt SSH.

An ACL bypass flaw was found in pacemaker. An attacker having a local account on the cluster and in the haclient group could use IPC communication with various daemons directly to perform certain tasks that they would be prevented by ACLs from doing if they went through the configuration.

A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.

Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.

A flaw was found in Red Hat 3scale’s API docs URL, where it is accessible without credentials. This flaw allows an attacker to view sensitive information or modify service APIs. Versions before 3scale-2.10.0-ER1 are affected.

An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system.

An issue was discovered in LemonLDAP::NG (aka lemonldap-ng) 2.0.13. When using the RESTServer plug-in to operate a REST password validation service (for another LemonLDAP::NG instance, for example) and using the Kerberos authentication method combined with another method with the Combination authentication plug-in, any password will be recognized as valid for an existing user.

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 7u321, 8u311, 11.0.13, 17.0.1; Oracle GraalVM Enterprise Edition: 20.3.4 and 21.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.1 Base Score 5.3 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N).

The libobby server in inc/server.hpp in libnet6 (aka net6) before 1.3.14 does not perform authentication before checking the user name, which allows remote attackers to obtain sensitive information such as server-usage patterns by a particular user and color preferences.

The servlets invoked by httpha-invoker in JBoss Enterprise Application Platform before 5.1.2, SOA Platform before 5.2.0, BRMS Platform before 5.3.0, and Portal Platform before 4.3 CP07 perform access control only for the GET and POST methods, which allow remote attackers to bypass authentication by sending a request with a different method. NOTE: this vulnerability exists because of a CVE-2010-0738 regression.

Apache Shiro before 1.7.0, when using Apache Shiro with Spring, a specially crafted HTTP request may cause an authentication bypass.
