OpenVPN 3 Core Library version 3.6 and 3.6.1 allows a man-in-the-middle attacker to bypass the certificate authentication by issuing an unrelated server certificate using the same hostname found in the verify-x509-name option in a client configuration.
CWE-295
CVE-2021-35497
The FTL Server (tibftlserver) and Docker images containing tibftlserver components of TIBCO Software Inc.’s TIBCO ActiveSpaces – Community Edition, TIBCO ActiveSpaces – Developer Edition, TIBCO ActiveSpaces – Enterprise Edition, TIBCO FTL – Community Edition, TIBCO FTL – Developer Edition, TIBCO FTL – Enterprise Edition, TIBCO eFTL – Community Edition, TIBCO eFTL – Developer Edition, and TIBCO eFTL – Enterprise Edition contain a vulnerability that theoretically allows a non-administrative, authenticated FTL user to trick the affected components into creating illegitimate certificates. These maliciously generated certificates can be used to enable man-in-the-middle attacks or to escalate privileges so that the malicious user has administrative privileges. Affected releases are TIBCO Software Inc.’s TIBCO ActiveSpaces – Community Edition: versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.6.1, and 4.6.2, TIBCO ActiveSpaces – Developer Edition: versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.6.1, and 4.6.2, TIBCO ActiveSpaces – Enterprise Edition: versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.6.1, and 4.6.2, TIBCO FTL – Community Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0, TIBCO FTL – Developer Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0, TIBCO FTL – Enterprise Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0, TIBCO eFTL – Community Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0, TIBCO eFTL – Developer Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0, and TIBCO eFTL – Enterprise Edition: versions 6.2.0, 6.3.0, 6.3.1, 6.4.0, 6.5.0, 6.6.0, 6.6.1, and 6.7.0.
CVE-2021-35193
Patterson Application Service in Patterson Eaglesoft 18 through 21 accepts the same certificate authentication across different customers’ installations (that have the same software version). This provides remote access to SQL database credentials. (In the normal use of the product, retrieving those credentials only occurs after a username/password authentication step; however, this authentication step is on the client side, and an attacker can develop their own client that skips this step.)
CVE-2021-34599
Affected versions of CODESYS Git in Versions prior to V1.1.0.0 lack certificate validation in HTTPS handshakes. CODESYS Git does not implement certificate validation by default, so it does not verify that the server provides a valid and trusted HTTPS certificate. Since the certificate of the server to which the connection is made is not properly verified, the server connection is vulnerable to a man-in-the-middle attack.
CVE-2021-3460
The Motorola MH702x devices, prior to version 2.0.0.301, do not properly verify the server certificate during communication with the support server which could lead to the communication channel being accessible by an attacker.
CVE-2021-34558
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.
