keycloak: missing signatures validation on CRL used to verify client certificates

A vulnerability was found in keycloak before 6.0.2. The X.509 authenticator supports the verification of client certificates through the CRL, where the CRL list can be obtained from the URL provided in the certificate itself (CDP) or through the separately configured path. The CRL are often available over the network through unsecured protocols ('http' or 'ldap') and hence the caller should verify the signature and possibly the certification path. Keycloak currently doesn't validate signatures on CRL, which can result in a possibility of various attacks like man-in-the-middle.

kubevirt/virt-cdi-importer: improper TLS certificate validation

Kubevirt/virt-cdi-importer, versions 1.4.0 to 1.5.3 inclusive, were reported to disable TLS certificate validation when importing data into PVCs from container registries. This could enable man-in-the-middle attacks between a container registry and the virt-cdi-component, leading to possible undetected tampering of trusted container image content.

dovecot: Improper certificate validation

It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users.

An issue has been found in PowerDNS Recursor versions 4.1.x before 4.1.9 where records in the answer section of responses received from authoritative servers with the AA flag not set were not properly validated, allowing an attacker to bypass DNSSEC validation.

Apps Manager unverified SSL certs in Cloud Controller proxy

Pivotal Application Service (PAS), versions 2.2.x prior to 2.2.12, 2.3.x prior to 2.3.7 and 2.4.x prior to 2.4.3, contain apps manager that uses a cloud controller proxy that fails to verify SSL certs. A remote unauthenticated attacker that could hijack the Cloud Controller's DNS record could intercept access tokens sent to the Cloud Controller, giving the attacker access to the user's resources in the Cloud Controller

UAA allows users to modify their own email address

Cloud Foundry UAA, versions prior to v70.0, allows a user to update their own email address. A remote authenticated user can impersonate a different user by changing their email address to that of a different user.

Data Protection Central versions 1.0, 1.0.1, 18.1, 18.2, and 19.1 contains an Improper Certificate Chain of Trust Vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability by obtaining a CA signed certificate from Data Protection Central to impersonate a valid system to compromise the integrity of data.

Dell EMC Enterprise Copy Data Management (eCDM) versions 1.0, 1.1, 2.0, 2.1, and 3.0 contain a certificate validation vulnerability. An unauthenticated remote attacker may potentially exploit this vulnerability to carry out a man-in-the-middle attack by supplying a crafted certificate and intercepting the victim's traffic to view or modify a victim’s data in transit.

Missing TLS certificate validation for HTTPS connections in osc

Open Build Service before version 0.165.4 diddn't validate TLS certificates for HTTPS connections with the osc client binary

An issue was discovered in Scytl sVote 2.1. Because the IP address from an X-Forwarded-For header (which can be manipulated client-side) is used for the internal application logs, an attacker can inject wrong IP addresses into these logs.

Traefik 2.x, in certain configurations, allows HTTPS sessions to proceed without mutual TLS verification in a situation where ERR_BAD_SSL_CLIENT_AUTH_CERT should have occurred.

OpenDMARC through 1.3.2 and 1.4.x, when used with pypolicyd-spf 2.0.2, allows attacks that bypass SPF and DMARC authentication in situations where the HELO field is inconsistent with the MAIL FROM field.

The remote keyless system on Honda HR-V 2017 vehicles sends the same RF signal for each door-open request, which might allow a replay attack.

Gateways/Gateway.php in Heartland & Global Payments PHP SDK before 2.0.0 does not enforce SSL certificate validations.

The Authorized Addresses feature in the Postie plugin 1.9.40 for WordPress allows remote attackers to publish posts by spoofing the From information of an email message.

Cisco Web Security Appliance HTTPS Certificate Denial of Service Vulnerability

A vulnerability in the HTTPS decryption feature of Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Secure Sockets Layer (SSL) server certificates. An attacker could exploit this vulnerability by installing a malformed certificate in a web server and sending a request to it through the Cisco WSA. A successful exploit could allow the attacker to cause an unexpected restart of the proxy process on an affected device.

Cisco Small Business Switches Secure Shell Certificate Authentication Bypass Vulnerability

A vulnerability in the Secure Shell (SSH) authentication process of Cisco Small Business Switches software could allow an attacker to bypass client-side certificate authentication and revert to password authentication. The vulnerability exists because OpenSSH mishandles the authentication process. An attacker could exploit this vulnerability by attempting to connect to the device via SSH. A successful exploit could allow the attacker to access the configuration as an administrative user if the default credentials are not changed. There are no workarounds available; however, if client-side certificate authentication is enabled, disable it and use strong password authentication. Client-side certificate authentication is disabled by default.

Cisco IOS and IOS XE Software Smart Call Home Certificate Validation Vulnerability

A vulnerability in the Cisco Smart Call Home feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized read access to sensitive data using an invalid certificate. The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software.

Cisco IOS and IOS XE Software Network Plug-and-Play Agent Certificate Validation Vulnerability

A vulnerability in the Cisco Network Plug-and-Play (PnP) agent of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data. The vulnerability exists because the affected software insufficiently validates certificates. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt and modify confidential information on user connections to the affected software.

Cisco Prime Infrastructure Certificate Validation Vulnerability

A vulnerability in the Identity Services Engine (ISE) integration feature of Cisco Prime Infrastructure (PI) could allow an unauthenticated, remote attacker to perform a man-in-the-middle attack against the Secure Sockets Layer (SSL) tunnel established between ISE and PI. The vulnerability is due to improper validation of the server SSL certificate when establishing the SSL tunnel with ISE. An attacker could exploit this vulnerability by using a crafted SSL certificate and could then intercept communications between the ISE and PI. A successful exploit could allow the attacker to view and alter potentially sensitive information that the ISE maintains about clients that are connected to the network. This vulnerability affects Cisco Prime Infrastructure Software Releases 2.2 through 3.4.0 when the PI server is integrated with ISE, which is disabled by default.
