CVE-2023-38686 1 Matrix 1 Sydent 2024-11-21 9.3 Critical
Sydent is an identity server for the Matrix communications protocol. Prior to version 2.5.6, if configured to send emails using TLS, Sydent does not verify SMTP servers' certificates. This makes Sydent's emails vulnerable to interception via a man-in-the-middle (MITM) attack. Attackers with privileged access to the network can intercept room invitations and address confirmation emails. This is patched in Sydent 2.5.6. When patching, make sure that Sydent trusts the certificate of the server it is connecting to. This should happen automatically when using properly issued certificates. Those who use self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of your operating system. As a workaround, one can ensure Sydent's emails fail to send by setting the configured SMTP server to a loopback or non-routable address under one's control which does not have a listening SMTP server.

CVE-2023-38325 1 Cryptography.io 1 Cryptography 2024-11-21 7.5 High
The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options.
CVE-2023-35845 2 Anaconda, Linux 2 Anaconda3, Linux Kernel 2024-11-21 4.7 Medium
Anaconda 3 2023.03-1-Linux allows local users to disrupt TLS certificate validation by modifying the cacert.pem file used by the installed pip program. This occurs because many files are installed as world-writable on Linux, ignoring umask, even when these files are installed as root. Miniconda is also affected.
CVE-2023-34143 3 Hitachi, Linux, Microsoft 3 Device Manager, Linux Kernel, Windows 2024-11-21 5.6 Medium
Improper Validation of Certificate with Host Mismatch vulnerability in Hitachi Device Manager on Windows, Linux (Device Manager Server, Device Manager Agent, Host Data Collector components) allows Man in the Middle Attack.This issue affects Hitachi Device Manager: before 8.8.5-02.
CVE-2023-32464 1 Dell 90 Vxrail D560, Vxrail D560 Firmware, Vxrail D560f and 87 more 2024-11-21 2.7 Low
Dell VxRail, versions prior to 7.0.450, contain an improper certificate validation vulnerability. A high privileged remote attacker may potentially exploit this vulnerability to carry out a man-in-the-middle attack by supplying a crafted certificate and intercepting the victim's traffic to view or modify a victim’s data in transit.
CVE-2023-32330 1 Ibm 1 Security Verify Access 2024-11-21 7.5 High
IBM Security Verify Access 10.0.0.0 through 10.0.6.1 uses insecure calls that could allow an attacker on the network to take control of the server. IBM X-Force ID: 254977.
CVE-2023-31580 1 Networknt 1 Light-oauth2 2024-11-21 5.9 Medium
light-oauth2 before version 2.1.27 obtains the public key without any verification. This could allow attackers to authenticate to the application with a crafted JWT token.
CVE-2023-31484 3 Cpanpm Project, Perl, Redhat 3 Cpanpm, Perl, Enterprise Linux 2024-11-21 8.1 High
CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS.
CVE-2023-31421 1 Elastic 4 Apm Server, Elastic Agent, Elastic Beats and 1 more 2024-11-21 5.9 Medium
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.
CVE-2023-31190 1 Bluemark 2 Dronescout Ds230, Dronescout Ds230 Firmware 2024-11-21 8.1 High
DroneScout ds230 Remote ID receiver from BlueMark Innovations is affected by an Improper Authentication vulnerability during the firmware update procedure. Specifically, the firmware update procedure ignores and does not check the validity of the TLS certificate of the HTTPS endpoint from which the firmware update package (.tar.bz2 file) is downloaded. An attacker with the ability to put himself in a Man-in-the-Middle situation (e.g., DNS poisoning, ARP poisoning, control of a node on the route to the endpoint, etc.) can trick the DroneScout ds230 to install a crafted malicious firmware update containing arbitrary files (e.g., executable and configuration) and gain administrative (root) privileges on the underlying Linux operating system. This issue affects DroneScout ds230 firmware from version 20211210-1627 through 20230329-1042.
CVE-2023-30729 1 Samsung 1 Email 2024-11-21 8.1 High
Improper Certificate Validation in Samsung Email prior to version 6.1.82.0 allows remote attacker to intercept the network traffic including sensitive information.
CVE-2023-30222 1 4d 1 Server 2024-11-21 7.5 High
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.
CVE-2023-2422 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2024-11-21 5.5 Medium
A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients.
CVE-2023-29175 1 Fortinet 2 Fortios, Fortiproxy 2024-11-21 4.4 Medium
An improper certificate validation vulnerability [CWE-295] in FortiOS 6.2 all versions, 6.4 all versions, 7.0.0 through 7.0.10, 7.2.0 and FortiProxy 1.2 all versions, 2.0 all versions, 7.0.0 through 7.0.9, 7.2.0 through 7.2.3 may allow a remote and unauthenticated attacker to perform a Man-in-the-Middle attack on the communication channel between the vulnerable device and the remote FortiGuard's map server.
