CVE-2015-3152 6 Debian, Fedoraproject, Mariadb and 3 more 14 Debian Linux, Fedora, Mariadb and 11 more 2025-04-12 5.9 Medium
Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack.
CVE-2014-0132 2 Fedoraproject, Redhat 2 389 Directory Server, Enterprise Linux 2025-04-12 N/A
The SASL authentication functionality in 389 Directory Server before 1.2.11.26 allows remote authenticated users to connect as an arbitrary user and gain privileges via the authzid parameter in a SASL/GSSAPI bind.
CVE-2014-0092 2 Gnu, Redhat 5 Gnutls, Enterprise Linux, Rhel Els and 2 more 2025-04-12 N/A
lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2014-0041 1 Redhat 1 Openstack 2025-04-12 N/A
OpenStack Heat Templates (heat-templates), as used in Red Hat Enterprise Linux OpenStack Platform 4.0, sets sslverify to false for certain Yum repositories, which disables SSL protection and allows man-in-the-middle attackers to prevent updates via unspecified vectors.
CVE-2014-0036 1 Amos Benari 1 Rbovirt 2025-04-12 N/A
The rbovirt gem before 0.0.24 for Ruby uses the rest-client gem with SSL verification disabled, which allows remote attackers to conduct man-in-the-middle attacks via unspecified vectors.
CVE-2015-3455 4 Fedoraproject, Oracle, Redhat and 1 more 5 Fedora, Linux, Solaris and 2 more 2025-04-12 N/A
Squid 3.2.x before 3.2.14, 3.3.x before 3.3.14, 3.4.x before 3.4.13, and 3.5.x before 3.5.4, when configured with client-first SSL-bump, do not properly validate the domain or hostname fields of X.509 certificates, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate.
CVE-2013-7449 3 Canonical, Hexchat Project, Xchat 4 Ubuntu Linux, Hexchat, Xchat and 1 more 2025-04-12 N/A
The ssl_do_connect function in common/server.c in HexChat before 2.10.2, XChat, and XChat-GNOME does not verify that the server hostname matches a domain name in the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2013-6444 1 Pywbem Project 1 Pywbem 2025-04-12 N/A
PyWBEM 0.7 and earlier does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
CVE-2013-4488 1 Libgadu 1 Libgadu 2025-04-12 N/A
libgadu before 1.12.0 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers.
CVE-2015-8960 7 Apple, Google, Ietf and 4 more 18 Safari, Chrome, Transport Layer Security and 15 more 2025-04-12 8.1 High
The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue.
CVE-2014-8642 2 Mozilla, Opensuse 3 Firefox, Seamonkey, Opensuse 2025-04-12 N/A
Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during a session in which there was an incorrect decision to accept a compromised and revoked certificate.
CVE-2014-8151 2 Apple, Haxx 2 Mac Os X, Libcurl 2025-04-12 N/A
The darwinssl_connect_step1 function in lib/vtls/curl_darwinssl.c in libcurl 7.31.0 through 7.39.0, when using the DarwinSSL (aka SecureTransport) back-end for TLS, does not check if a cached TLS session validated the certificate when reusing the session, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2014-7144 2 Openstack, Redhat 3 Keystonemiddleware, Python-keystoneclient, Openstack 2025-04-12 N/A
OpenStack keystonemiddleware (formerly python-keystoneclient) 0.x before 0.11.0 and 1.x before 1.2.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate.
CVE-2016-7444 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.
CVE-2012-6153 2 Apache, Redhat 13 Commons-httpclient, Developer Toolset, Jboss Bpms and 10 more 2025-04-12 N/A
http/conn/ssl/AbstractVerifier.java in Apache Commons HttpClient before 4.2.3 does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a certificate with a subject that specifies a common name in a field that is not the CN field. NOTE: this issue exists because of an incomplete fix for CVE-2012-5783.
CVE-2015-1852 3 Canonical, Openstack, Redhat 4 Ubuntu Linux, Keystonemiddleware, Python-keystoneclient and 1 more 2025-04-12 N/A
The s3_token middleware in OpenStack keystonemiddleware before 1.6.0 and python-keystoneclient before 1.4.0 disables certification verification when the "insecure" option is set in a paste configuration (paste.ini) file regardless of the value, which allows remote attackers to conduct man-in-the-middle attacks via a crafted certificate, a different vulnerability than CVE-2014-7144.
CVE-2014-3691 2 Redhat, Theforeman 5 Openstack, Openstack-installer, Satellite and 2 more 2025-04-12 N/A
Smart Proxy (aka Smart-Proxy and foreman-proxy) in Foreman before 1.5.4 and 1.6.x before 1.6.2 does not validate SSL certificates, which allows remote attackers to bypass intended authentication and execute arbitrary API requests via a request without a certificate.
CVE-2014-3694 5 Canonical, Debian, Opensuse and 2 more 5 Ubuntu Linux, Debian Linux, Opensuse and 2 more 2025-04-12 N/A
The (1) bundled GnuTLS SSL/TLS plugin and the (2) bundled OpenSSL SSL/TLS plugin in libpurple in Pidgin before 2.10.10 do not properly consider the Basic Constraints extension during verification of X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2016-1280 1 Juniper 1 Junos 2025-04-12 N/A
PKId in Juniper Junos OS before 12.1X44-D52, 12.1X46 before 12.1X46-D37, 12.1X47 before 12.1X47-D30, 12.3 before 12.3R12, 12.3X48 before 12.3X48-D20, 13.3 before 13.3R10, 14.1 before 14.1R8, 14.1X53 before 14.1X53-D40, 14.2 before 14.2R7, 15.1 before 15.1R4, 15.1X49 before 15.1X49-D20, 15.1X53 before 15.1X53-D60, and 16.1 before 16.1R1 allow remote attackers to bypass an intended certificate validation mechanism via a self-signed certificate with an Issuer name that matches a valid CA certificate enrolled in Junos.
CVE-2009-5138 2 Gnu, Redhat 2 Gnutls, Enterprise Linux 2025-04-12 N/A
GnuTLS before 2.7.6, when the GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT flag is not enabled, treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates, a different vulnerability than CVE-2014-1959.
