Title
NETGEAR RAX30 Improper Certificate Validation Remote Code Execution Vulnerability
Summary
NETGEAR RAX30 Improper Certificate Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the downloading of files via HTTPS. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-19589.

Title
SSL Certificates are not checked for E-Mail Handling
Summary
The functions to fetch e-mail via POP3 or IMAP as well as sending e-mail via SMTP use OpenSSL for static SSL or TLS based communication. As the
SSL_get_verify_result() function is not used the certificated is trusted always and it can not be ensured that the certificate
satisfies all necessary security requirements.
This could allow an
attacker to use an invalid certificate to claim to be a trusted host,
use expired certificates, or conduct other attacks that could be
detected if the certificate is properly validated.
This issue affects OTRS: from 7.0.X before 7.0.47, from 8.0.X before 8.0.37; ((OTRS)) Community Edition: from 6.0.X through 6.0.34.

Title
Improper Certificate Validation in Bitdefender Total Security HTTPS Scanning (VA-11158)
Summary
A vulnerability has been identified in Bitdefender Total Security HTTPS scanning functionality where the software fails to properly validate website certificates. Specifically, if a site certificate lacks the "Server Authentication" specification in the Extended Key Usage extension, the product does not verify the certificate's compliance with the site, deeming such certificates as valid. This flaw could allow an attacker to perform a Man-in-the-Middle (MITM) attack, intercepting and potentially altering communications between the user and the website.

Title
HTTPS Certificate Validation Issue in Bitdefender Safepay (VA-11167)
Summary
A vulnerability has been identified in Bitdefender Safepay's handling of HTTPS connections. The issue arises when the product blocks a connection due to an untrusted server certificate but allows the user to add the site to exceptions, resulting in the product trusting the certificate for subsequent HTTPS scans. This vulnerability allows an attacker to perform a Man-in-the-Middle (MITM) attack by using a self-signed certificate, which the product will trust after the site has been added to exceptions. This can lead to the interception and potential alteration of secure communications.

Mitigation
Phases: Architecture and Design, Implementation
Description:
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
Phase: Implementation
Description:
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
