Title
D-Link DIR-2640 HNAP PrivateLogin Authentication Bypass Vulnerability
Summary
D-Link DIR-2640 HNAP PrivateLogin Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-2640 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the web management interface, which listens on TCP port 80 by default. A crafted XML element in the login request can cause authentication to succeed without providing proper credentials. An attacker can leverage this vulnerability to bypass authentication on the system.
. Was ZDI-CAN-19545.

Title
Network authentication attack via pam_krb5
Summary
pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password. However, if a keytab is not provisioned on the system, pam_krb5 has no way to validate the response from the KDC, and essentially trusts the tgt provided over the network as being valid. In a non-default FreeBSD installation that leverages pam_krb5 for authentication and does not have a keytab provisioned, an attacker that is able to control both the password and the KDC responses can return a valid tgt, allowing authentication to occur for any user on the system.
Severity

Title
D-Link DIR-2150 LoginPassword Incorrect Implementation of Authentication Algorithm Authentication Bypass Vulnerability
Summary
D-Link DIR-2150 LoginPassword Incorrect Implementation of Authentication Algorithm Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-2150 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the SOAP API interface, which listens on TCP port 80 by default. A crafted login request can cause authentication to succeed without providing proper credentials. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-20552.
Severity
8.8 (High)

Title
Issuer not verified from obtained token in user_oidc
Summary
user_oidc provides the OIDC connect user backend for Nextcloud, an open-source cloud platform. Starting in version 1.0.0 and prior to version 1.3.3, missing verification of the issuer would have allowed an attacker to perform a man-in-the-middle attack returning corrupted or known token they also have access to. user_oidc 1.3.3 contains a patch. No known workarounds are available.

Title
D-Link DIR-X3260 prog.cgi Incorrect Implementation of Authentication Algorithm Authentication Bypass Vulnerability
Summary
D-Link DIR-X3260 prog.cgi Incorrect Implementation of Authentication Algorithm Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-X3260 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the prog.cgi executable. The issue results from an incorrect implementation of the authentication algorithm. An attacker can leverage this vulnerability to bypass authentication on the device. Was ZDI-CAN-21100.

Title
Shadow-utils: possible password leak during passwd(1) change
Summary
A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.

CAPEC-90: Reflection Attack in Authentication Protocol
An adversary can abuse an authentication protocol susceptible to reflection attack in order to defeat it. Doing so allows the adversary illegitimate access to the target system, without possessing the requisite credentials. Reflection attacks are of great concern to authentication protocols that rely on a challenge-handshake or similar mechanism. An adversary can impersonate a legitimate user and can gain illegitimate access to the system by successfully mounting a reflection attack during authentication.
