A vulnerability in the Cisco Network Plug and Play application of Cisco IOS 12.4 through 15.6 and Cisco IOS XE 3.3 through 16.4 could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data by 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 Bug IDs: CSCvc33171.

An Authentication Bypass by Spoofing issue was discovered in LAVA Ether-Serial Link (ESL) running firmware versions 6.01.00/29.03.2007 and prior versions. An improper authentication vulnerability has been identified, which, if exploited, would allow an attacker with the same IP address to bypass authentication by accessing a specific uniform resource locator.

Prior to v 7.6, the Install Norton Security (INS) product can be susceptible to a certificate spoofing vulnerability, which is a type of attack whereby a maliciously procured certificate binds the public key of an attacker to the domain name of the target.

A vulnerability has been discovered in the Auth0 passport-wsfed-saml2 library affecting versions < 3.0.5. This vulnerability allows an attacker to impersonate another user and potentially elevate their privileges if the SAML identity provider does not sign the full SAML response (e.g., only signs the assertion within the response).

GitLab 9.4.x before 9.4.2 does not support LDAP SSL certificate verification, but a verify_certificates LDAP option was mentioned in the 9.4 release announcement. This issue occurred because code was not merged. This is related to use of the omniauth-ldap library and the gitlab_omniauth-ldap gem.

rubygem-net-ldap: Missing SSL Certificate Validation

The Net::LDAP (aka net-ldap) gem before 0.16.0 for Ruby has Missing SSL Certificate Validation.

The Access CX App for Android prior to 2.0.0.1 and for iOS prior to 2.0.2 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The RBB SPEED TEST App for Android version 2.0.3 and earlier, RBB SPEED TEST App for iOS version 2.1.0 and earlier does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

puppet-apache: Possible TLS trust misconfiguration in puppetlabs-apache

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.

A specially crafted x509 certificate can cause a single out of bounds byte overwrite in wolfSSL through 3.10.2 resulting in potential certificate validation vulnerabilities, denial of service and possible remote code execution. In order to trigger this vulnerability, the attacker needs to supply a malicious x509 certificate to either a server or a client application using this library.

The transit path validation code in Heimdal before 7.3 might allow attackers to bypass the capath policy protection mechanism by leveraging failure to add the previous hop realm to the transit path of issued tickets.

A vulnerability in the Autonomic Networking feature of Cisco IOS XE Software could allow an unauthenticated, remote, autonomic node to access the Autonomic Networking infrastructure of an affected system, after the certificate for the autonomic node has been revoked. This vulnerability affected devices that are running Release 16.x of Cisco IOS XE Software and are configured to use Autonomic Networking. This vulnerability does not affect devices that are running an earlier release of Cisco IOS XE Software or devices that are not configured to use Autonomic Networking. More Information: CSCvd22328. Known Affected Releases: 15.5(1)S3.1 Denali-16.2.1.

The (1) update and (2) package-installation features in MODX Revolution 2.5.4-pl and earlier do not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and trigger the execution of arbitrary code via a crafted certificate.

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.

Huawei SMC2.0 with software of V100R003C10, V100R005C00SPC100, V100R005C00SPC101B001T, V100R005C00SPC102, V100R005C00SPC103, V100R005C00SPC200, V100R005C00SPC201T, V500R002C00, V600R006C00 has an input validation vulnerability when handle TLS and DTLS handshake with certificate. Due to the insufficient validation of received PKI certificates, remote attackers could exploit this vulnerability to crash the TLS module.

LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx.

kauth: service invoking dbus is not properly checked and allows local privilege escalation

KDE kdelibs before 4.14.32 and KAuth before 5.34 allow local users to gain root privileges by spoofing a callerID and leveraging a privileged helper app.

An error was found in the X-Pack Security TLS trust manager for versions 5.0.0 to 5.5.1. If reloading the trust material fails the trust manager will be replaced with an instance that trusts all certificates. This could allow any node using any certificate to join a cluster. The proper behavior in this instance is for the TLS trust manager to deny all certificates.

The Quest Information Systems Indiana Voters app 1.1.24 for iOS does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

The MoboTap Dolphin Web Browser - Fast Private Internet Search app 9.23.0 through 9.23.2 for iOS does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
