Title
frr: ospf6d fails to enforce all OSPFv3 packets use IPv6 link-local addresses
Summary
In all prior released versions of FRRouting, the OSPFv3 (for IPv6) implementation does not check that OSPFv3 packets have a link-local source address and either a link-local destination or one of the protocol multicast destination groups. This may enable malicious actors to establish OSPFv3 adjacencies from unexpectedly, distant IPv6 hosts. Proper usage of OSPFv3 authentication trailers (RFC 7166, as is best practice) prevents full exploitation of this issue, though may allow a malicious actor to waste CPU on authentication checks.
Note the linked PR #23935 is not sufficient to fix the issue as it only verifies the source address. It is the destination address that must be checked.
Required configuration: The OSPFv3 for IPv6 routing protocol must be running (ospf6d process) and in use (enabled globally with "router ospf6" and on specific interfaces with "ipv6 ospf6 area".)
Workaround: either:
* configure OSPFv3 authentication trailers ("ipv6 ospf6 authentication")
* or ensure through firewall configuration that only packets with link-local or multicast destination addresses are accepted on input for IPv6 protocol 89 (OSPF). Note that checking the source address is insufficient, as some routers may (unexpectedly) forward packets with global-scoped IPv6 destination addresses even if they have link-local source addresses.

Title
Improper Multi-Factor Authentication Validation Allows Authentication Bypass
Summary
Incorrect authentication vulnerability in the TSplus Remote Access multi-factor authentication (MFA) mechanism. A remote attacker authenticated with valid first-factor credentials could bypass the second-factor verification because the authentication flow does not correctly apply the MFA validation result, allowing the attacker to complete the login without a valid second-factor token and gain access to protected applications and resources.

Title
Apache Tomcat: JNDIRealm bind credential validation fails open for non-GSSAPI SASL mechanisms
Summary
A missing critical step in authentication vulnerability in Apache Tomcat when the JNDI realm was configured with with a non GSSAPI SASL authentication mechanism allowed attackers to authenticate without providing the correct password.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.26, from 10.1.0-M1 through 10.1.60, from 9.0.0.M1 through 9.0.122.
The following versions were EOL at the time the CVE was created but are known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected.
Users are recommended to upgrade to version 11.0.27, 10.1.61 or 9.0.123, which fix the issue.

Title
grav-plugin-login 3.8.7 through 3.9.6 Two-Factor Authentication Bypass
Summary
grav-plugin-login (the Grav CMS Login plugin) versions >= 3.8.7 and < 3.9.7 allow the two-factor authentication challenge to be bypassed for content gated by the authenticated() Twig function or the [authenticated] shortcode. On sites with 2FA enabled, Login::isAuthenticated() checked only the session flag indicating that the password step had succeeded, not the flag indicating that login had completed, so a session sitting at the 2FA code prompt was treated as fully authenticated. An attacker who knows a member's password but cannot answer that member's second factor can therefore read member-only content rendered by the no-argument authenticated() or group authenticated(null, 'group') forms and by [authenticated]; the inverse [guest] shortcode is likewise evaluated too early. Impact is limited to disclosure of that content: the attacker does not obtain a completed session, cannot access pages protected by an access: rule, and cannot act as the user. The authenticated('some.permission') form, which goes through UserObject::authorize(), is not affected. Fixed in grav-plugin-login 3.9.7.

Title
Apache MINA SSHD: LDAP password authentication ineffective
Summary
A missing check in LdapPasswordAuthenticator in component sshd-ldap in Apache MINA SSHD versions 1.2.0 to 2.19.0 or 3.0.0-M1 to 3.0.0-M5 bypassed authentication checks.
Apache MINA SSHD is a Java library for client-side and server-side SSH. The optional sshd-ldap component provides support for integrating password and publickey authentication on the server side with an LDAP server.
sshd-ldap is an optional component. SSH servers implemented with Apache MINA SSHD are affected only if they use sshd-ldap and do configure an LdapPasswordAuthenticator to be used for password authentication. Normal password authentication via the built-in mechanisms in sshd-core is _not_ affected by this vulnerability, which concerns only LdapPasswordAuthenticator.
Users are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue.

Title
Apache MINA SSHD: Repeated-publickey policy bypass on server
Summary
Apache MINA SSHD is a Java library for client-side and server-side SSH. SSH servers can be configured to require multi-authentication schemes, for instance two different public keys, not just one. In OpenSSH, this would be done by setting in sshd_config AuthenticationMethods "publickey,publickey". Apache MINA SSHD provides an equivalent configuration mechanism.
In Apache MINA SSHD versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5 the server code in component sshd-core does not enforce that the two public keys presented are different. A user can thus successfully authenticate with only one of the two key pairs required by presenting this single key twice. This is a partial authentication bypass.
Users are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.

Title
phpMyFAQ before 4.1.7 2FA Bypass via Remember-Me Cookie
Summary
phpMyFAQ before 4.1.7 contains a two-factor authentication bypass vulnerability where remember-me tokens are issued before 2FA verification completes. Attackers with valid credentials can obtain a remember-me cookie, skip the 2FA challenge, and replay the cookie to gain full authenticated access without second-factor verification.
