OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on (1) the number of extra reductions during Montgomery reduction, and (2) the use of different integer multiplication algorithms ("Karatsuba" and normal).

The D-Link DIR-615 device before v20.12PTb04 doesn't use SSL for any of the authenticated pages. Also, it doesn't allow the user to generate his own SSL Certificate. An attacker can simply monitor network traffic to steal a user's credentials and/or credentials of users being added while sniffing the traffic.

IBM Storage Defender - Resiliency Service 2.0.0 through 2.0.9 does not properly validate a certificate which could allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client.

Versions of the puppetlabs-apache module prior to 1.11.1 and 2.1.0 make it very easy to accidentally misconfigure TLS trust. If you specify the `ssl_ca` parameter but do not specify the `ssl_certs_dir` parameter, a default will be provided for the `ssl_certs_dir` that will trust certificates from any of the system-trusted certificate authorities. This did not affect FreeBSD.

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.

It was found that CloudForms does not verify that the server hostname matches the domain name in the certificate when using a custom CA and communicating with Red Hat Virtualization (RHEV) and OpenShift. This would allow an attacker to spoof RHEV or OpenShift systems and potentially harvest sensitive information from CloudForms.

An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote server to obtain security trust well improperly. This indication of trust may be passed along to clients, allowing access to unsafe or hijacked services.

IBM Security Verify Bridge 1.0.5.0 could allow a user to obtain sensitive information due to improper certificate validation. IBM X-Force ID: 208155.

Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. In versions 2.5.0 through 2.13.0, ElasticsearchWriter, GelfWriter, InfluxdbWriter and Influxdb2Writer do not verify the server's certificate despite a certificate authority being specified. Icinga 2 instances which connect to any of the mentioned time series databases (TSDBs) using TLS over a spoofable infrastructure should immediately upgrade to version 2.13.1, 2.12.6, or 2.11.11 to patch the issue. Such instances should also change the credentials (if any) used by the TSDB writer feature to authenticate against the TSDB. There are no workarounds aside from upgrading.

An issue was discovered in Prosody before 0.11.9. The undocumented dialback_without_dialback option in mod_dialback enables an experimental feature for server-to-server authentication. It does not correctly authenticate remote server certificates, allowing a remote server to impersonate another server (when this option is enabled).

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

A potential security vulnerability has been identified in the HP ThinUpdate utility (also known as HP Recovery Image and Software Download Tool) which may lead to information disclosure. HP is releasing mitigation for the potential vulnerability.

Nextcloud Android Client is the Android client for Nextcloud. Clients using the Nextcloud end-to-end encryption feature download the public and private key via an API endpoint. In versions prior to 3.16.1, the Nextcloud Android client skipped a step that involved the client checking if a private key belonged to a previously downloaded public certificate. If the Nextcloud instance served a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. The vulnerability is patched in version 3.16.1. As a workaround, do not add additional end-to-end encrypted devices to a user account.

In JetBrains YouTrack before 2024.1.29548 the SMTPS protocol communication lacked proper certificate hostname validation

IBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.8 could allow an attacker with access to the network to conduct spoofing attacks. An attacker could exploit this vulnerability using a certificate issued by a trusted authority to obtain sensitive information. IBM X-Force ID: 274713.

Permission verification vulnerability in distributed scenarios. Successful exploitation of this vulnerability may affect service confidentiality.

A flaw was found in Cockpit in versions prior to 260 in the way it handles the certificate verification performed by the System Security Services Daemon (SSSD). This flaw allows client certificates to authenticate successfully, regardless of the Certificate Revocation List (CRL) configuration or the certificate status. The highest threat from this vulnerability is to confidentiality.

The host name verification when using TLS with the WebSocket client was missing. It is now enabled by default. Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.9, 8.5.0 to 8.5.31, 8.0.0.RC1 to 8.0.52, and 7.0.35 to 7.0.88.

Dell BSAFE Micro Edition Suite, versions prior to 4.5.1, contain an Improper Certificate Validation vulnerability.

The TLS stack in Mono before 3.12.1 makes it easier for remote attackers to conduct cipher-downgrade attacks to EXPORT_RSA ciphers via crafted TLS traffic, related to the "FREAK" issue, a different vulnerability than CVE-2015-0204.

NETGEAR R8900, R9000, RAX120, and XR700 devices before 2020-01-20 are affected by Transport Layer Security (TLS) certificate private key disclosure.

Philips IntelliSpace Portal all versions of 8.0.x, and 7.0.x have an untrusted SSL certificate vulnerability this could allow an attacker to gain unauthorized access to resources and information.

Patterson Application Service in Patterson Eaglesoft 18 through 21 accepts the same certificate authentication across different customers' installations (that have the same software version). This provides remote access to SQL database credentials. (In the normal use of the product, retrieving those credentials only occurs after a username/password authentication step; however, this authentication step is on the client side, and an attacker can develop their own client that skips this step.)

duplicity 0.6.24 has improper verification of SSL certificates

The Smart Call Home (SCH) implementation in Cisco ASA Software 8.2 before 8.2(5.50), 8.4 before 8.4(7.15), 8.6 before 8.6(1.14), 8.7 before 8.7(1.13), 9.0 before 9.0(4.8), and 9.1 before 9.1(5.1) allows remote attackers to bypass certificate validation via an arbitrary VeriSign certificate, aka Bug ID CSCun10916.

Internet Systems Consortium (ISC) BIND 9.6.0 and earlier does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077 and CVE-2009-0025.

An issue was discovered in Mattermost Server before 3.9.0 when SAML is used. Encryption and signature verification are not mandatory.

It was discovered that when acting as TLS clients, Beats, Elastic Agent, APM Server, and Fleet Server did not verify whether the server certificate is valid for the target IP address; however, certificate signature validation is still performed. More specifically, when the client is configured to connect to an IP address (instead of a hostname) it does not validate the server certificate's IP SAN values against that IP address and certificate validation fails, and therefore the connection is not blocked as expected.

An information disclosure vulnerability in 4D SAS 4D Server Application v17, v18, v19 R7 and earlier allows attackers to retrieve password hashes for all users via eavesdropping.

In ca-certificates, there is a possible way to read encrypted TLS data due to untrusted cryptographic certificates. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
