Improper Certificate Validation

Starting with diego-release 2.55.0 and up to 2.69.0, and starting with CF Deployment 17.1 and up to 23.2.0, apps are accessible via another port on diego cells, allowing application ingress without a client certificate. If mTLS route integrity is enabled AND unproxied ports are turned off, then an attacker could connect to an application that should be only reachable via mTLS, without presenting a client certificate.Show less

Rapid7 Nexpose and InsightVM versions 6.6.82 through 6.6.177 fail to validate the certificate of the update server when downloading updates. This failure could allow an attacker in a privileged position on the network to provide their own HTTPS endpoint, or intercept communications to the legitimate endpoint. The attacker would need some pre-existing access to at least one node on the network path between the Rapid7-controlled update server and the Nexpose/InsightVM application, and the ability to either spoof the update server's FQDN or redirect legitimate traffic to the attacker's server in order to exploit this vulnerability. Note that even in this scenario, an attacker could not normally replace an update package with a malicious package, since the update process validates a separate, code-signing certificate, distinct from the HTTPS certificate used for communication. This issue was resolved on February 1, 2023 in update 6.6.178 of Nexpose and InsightVM. Show less

Dell PowerScale OneFS, versions 8.2.x-9.3.x, contains an Improper Certificate Validation vulnerability. An remote unauthenticated attacker could potentially exploit this vulnerability, leading to a full compromise of the system. Show less

A CWE-295: Improper Certificate Validation vulnerability exists that could cause the CAE software to give wrong data to end users when using CAE to configure devices. Additionally, credentials could leak which would enable an attacker the ability to log into the configuration tool and compromise other devices in the network. Affected Products: EcoStruxure™ Cybersecurity Admin Expert (CAE) (Versions prior to 2.2)Show less

In Apache::Session::Browseable before 1.3.6, validity of the X.509 certificate is not checked by default when connecting to remote LDAP backends, because the default configuration of the Net::LDAPS module for Perl is used. NOTE: this can, for example, be fixed in conjunction with the CVE-2020-16093 fix.Show less

In Apache::Session::LDAP before 0.5, validity of the X.509 certificate is not checked by default when connecting to remote LDAP backends, because the default configuration of the Net::LDAPS module for Perl is used. NOTE: this can, for example, be fixed in conjunction with the CVE-2020-16093 fix.Show less

Cloud Mobility for Dell EMC Storage, versions 1.3.0.X and below contains an Improper Check for Certificate Revocation vulnerability. A threat actor does not need any specific privileges to potentially exploit this vulnerability. An attacker could perform a man-in-the-middle attack and eavesdrop on encrypted communications from Cloud Mobility to Cloud Storage devices. Exploitation could lead to the compromise of secret and sensitive information, cloud storage connection downtime, and the integrity of the connection to the Cloud devices. Show less

If the user added a security exception for an invalid TLS certificate, opened an ongoing TLS connection with a server that used that certificate, and then deleted the exception, Firefox would have kept the connection alive, making it seem like the certificate was still trusted. This vulnerability affects Firefox < 107.Show less

When a TLS Certificate error occurs on a domain protected by the HSTS header, the browser should not allow the user to bypass the certificate error. On Firefox for Android, the user was presented with the option to bypass the error; this could only have been done by the user explicitly. <br>*This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102.Show less

After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5.Show less

When displaying the sender of an email, and the sender name contained the Braille Pattern Blank space character multiple times, Thunderbird would have displayed all the spaces. This could have been used by an attacker to send an email message with the attacker's digital signature, that was shown with an arbitrary sender email address chosen by the attacker. If the sender name started with a false email address, followed by many Braille space characters, the attacker's email address was not visible. Because Thunderbird compared the invisible sender address with the signature's email address, if the signing key or certificate was accepted by Thunderbird, the email was shown as having a valid digital signature. This vulnerability affects Thunderbird < 91.10.Show less

When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non-revoked. Revocation statements that used another revocation reason, or that didn't specify a revocation reason, were unaffected. This vulnerability affects Thunderbird < 91.8.Show less

The Apache Bookkeeper Java Client (before 4.14.6 and also 4.15.0) does not close the connection to the bookkeeper server when TLS hostname verification fails. This leaves the bookkeeper client vulnerable to a man in the middle attack. The problem affects BookKeeper client prior to versions 4.14.6 and 4.15.1.Show less

Traefik is an open source HTTP reverse proxy and load balancer. In affected versions there is a potential vulnerability in Traefik managing TLS connections. A router configured with a not well-formatted TLSOption is exposed with an empty TLSOption. For instance, a route secured using an mTLS connection set with a wrong CA file is exposed without verifying the client certificates. Users are advised to upgrade to version 2.9.6. Users unable to upgrade should check their logs to detect the error messages and fix your TLS options.Show less
