CVE-2020-5684 1 Nec 5 Ism Server, M120, M12e and 2 more 2020-12-28 5.8 MEDIUM 4.8 MEDIUM
iSM client versions from V5.1 prior to V12.1 running on NEC Storage Manager or NEC Storage Manager Express does not verify a server certificate properly, which allows a man-in-the-middle attacker to eavesdrop on an encrypted communication or alter the communication via a crafted certificate.
CVE-2018-8020 2 Apache, Debian 2 Tomcat Native, Debian Linux 2020-12-24 4.3 MEDIUM 7.4 HIGH
Apache Tomcat Native 1.2.0 to 1.2.16 and 1.1.23 to 1.1.34 has a flaw that does not properly check OCSP pre-produced responses, which are lists (multiple entries) of certificate statuses. Subsequently, revoked client certificates may not be properly identified, allowing for users to authenticate with revoked certificates to connections that require mutual TLS. Users not using OCSP checks are not affected by this vulnerability.
CVE-2020-29663 1 Icinga 1 Icinga 2020-12-18 6.4 MEDIUM 9.1 CRITICAL
Icinga 2 v2.8.0 through v2.11.7 and v2.12.2 has an issue where revoked certificates due for renewal will automatically be renewed, ignoring the CRL. This issue is fixed in Icinga 2 v2.11.8 and v2.12.3.
CVE-2018-20200 1 Squareup 1 Okhttp 2020-12-15 4.3 MEDIUM 5.9 MEDIUM
** DISPUTED ** CertificatePinner.java in OkHttp 3.x through 3.12.0 allows man-in-the-middle attackers to bypass certificate pinning by changing SSLContext and the boolean values while hooking the application. NOTE: This id is disputed because some parties don't consider this is a vulnerability. Their rationale can be found in https://github.com/square/okhttp/issues/4967.
CVE-2018-11747 1 Puppet 1 Discovery 2020-12-15 7.5 HIGH 9.8 CRITICAL
Previously, Puppet Discovery was shipped with a default generated TLS certificate in the nginx container. In version 1.4.0, a unique certificate will be generated on installation or the user will be able to provide their own TLS certificate for ingress.
CVE-2012-0955 1 Canonical 1 Software-properties 2020-12-07 5.8 MEDIUM 7.4 HIGH
software-properties was vulnerable to a person-in-the-middle attack due to incorrect TLS certificate validation in softwareproperties/ppa.py. software-properties didn't check TLS certificates under python2 and only checked certificates under python3 if a valid certificate bundle was provided. Fixed in software-properties version 0.92.
CVE-2020-29440 1 Tesla 2 Model X, Model X Firmware 2020-12-04 2.1 LOW 4.6 MEDIUM
Tesla Model X vehicles before 2020-11-23 do not perform certificate validation during an attempt to pair a new key fob with the body control module (BCM). This allows an attacker (who is inside a vehicle, or is otherwise able to send data over the CAN bus) to start and drive the vehicle with a spoofed key fob.
CVE-2020-28942 1 Primekey 1 Ejbca 2020-12-03 4.0 MEDIUM 4.3 MEDIUM
An issue exists in PrimeKey EJBCA before 7.4.3 when enrolling with EST while proxied through an RA over the Peers protocol. As a part of EJBCA's domain security model, the peer connector allows the restriction of client certificates (for the RA, not the end user) to a limited set of allowed CAs, thus restricting the accessibility of that RA to the rights it has within a specific role. While this works for other protocols such as CMP, it was found that the EJBCA enrollment over an EST implementation bypasses this check, allowing enrollment with a valid client certificate through any functioning and authenticated RA connected to the CA. NOTE: an attacker must already have a trusted client certificate and authorization to enroll against the targeted CA.
CVE-2020-8279 1 Nextcloud 1 Social 2020-11-25 5.8 MEDIUM 7.4 HIGH
Missing validation of server certificates for out-going connections in Nextcloud Social < 0.4.0 allowed a man-in-the-middle attack.
CVE-2020-27589 1 Synopsys 1 Hub-rest-api-python 2020-11-20 5.0 MEDIUM 7.5 HIGH
Synopsys hub-rest-api-python (aka blackduck on PyPI) version 0.0.25 - 0.0.52 does not validate SSL certificates in certain cases.
CVE-2017-1000256 2 Debian, Redhat 2 Debian Linux, Libvirt 2020-11-16 6.8 MEDIUM 8.1 HIGH
libvirt version 2.3.0 and later is vulnerable to a bad default configuration of "verify-peer=no" passed to QEMU by libvirt resulting in a failure to validate SSL/TLS certificates by default.
CVE-2020-27648 1 Synology 3 Diskstation Manager, Skynas, Skynas Firmware 2020-11-09 6.8 MEDIUM 9.0 CRITICAL
Improper certificate validation vulnerability in OpenVPN client in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2020-27649 1 Synology 1 Router Manager 2020-11-09 6.8 MEDIUM 9.0 CRITICAL
Improper certificate validation vulnerability in OpenVPN client in Synology Router Manager (SRM) before 1.2.4-8081 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2018-1000520 1 Arm 1 Mbed Tls 2020-11-05 5.0 MEDIUM 7.5 HIGH
ARM mbedTLS version 2.7.0 and earlier contains a Ciphersuite Allows Incorrectly Signed Certificates vulnerability in mbedtls_ssl_get_verify_result() that can result in ECDSA-signed certificates are accepted, when only RSA-signed ones should be.. This attack appear to be exploitable via Peers negotiate a TLS-ECDH-RSA-* ciphersuite. Any of the peers can then provide an ECDSA-signed certificate, when only an RSA-signed one should be accepted..
CVE-2019-8642 1 Apple 1 Mac Os X 2020-11-02 4.3 MEDIUM 3.3 LOW
An issue existed in the handling of S-MIME certificates. This issue was addressed with improved validation of S-MIME certificates. This issue is fixed in macOS Mojave 10.14.4, Security Update 2019-002 High Sierra, Security Update 2019-002 Sierra. Processing a maliciously crafted mail message may lead to S/MIME signature spoofing.
CVE-2020-3557 1 Cisco 1 Firepower Management Center 2020-10-28 5.0 MEDIUM 5.3 MEDIUM
A vulnerability in the host input API daemon of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted data stream to the host input daemon of the affected device. A successful exploit could allow the attacker to cause the host input daemon to restart. The attacker could use repeated attacks to cause the daemon to continuously reload, creating a DoS condition for the API.
CVE-2019-1886 1 Cisco 2 Asyncos, Web Security Appliance 2020-10-16 5.0 MEDIUM 8.6 HIGH
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.
CVE-2009-3767 4 Apple, Fedoraproject, Openldap and 1 more 4 Mac Os X, Fedora, Openldap and 1 more 2020-10-14 4.3 MEDIUM N/A
libraries/libldap/tls_o.c in OpenLDAP 2.2 and 2.4, and possibly other versions, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
CVE-2019-1859 1 Cisco 228 Sf200-24, Sf200-24 Firmware, Sf200-24fp and 225 more 2020-10-13 6.5 MEDIUM 7.2 HIGH
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.
CVE-2020-7041 4 Fedoraproject, Openfortivpn Project, Openssl and 1 more 5 Fedora, Openfortivpn, Openssl and 2 more 2020-10-09 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in openfortivpn 1.11.0 when used with OpenSSL 1.0.2 or later. tunnel.c mishandles certificate validation because an X509_check_host negative error code is interpreted as a successful return value.
