Summary
A vulnerability has been identified in COMOS V10.6 (All versions < V10.6.1), COMOS V10.6 (All versions < V10.6.1), NX V2412 (All versions < V2412.8700), NX V2506 (All versions < V2506.6000), Simcenter 3D (All versions < V2506.6000), Simcenter Femap (All versions < V2506.0002), Solid Edge SE2025 (All versions < V225.0 Update 10), Solid Edge SE2026 (All versions < V226.0 Update 1). The IAM client in affected products is missing server certificate validation while establishing TLS connections to the authorization server. This could allow an attacker to perform a man-in-the-middle attack.

CVE-2025-40896 (GCVE-0-2025-40896)
Vulnerability from cvelistv5 – Published: 2026-03-04 13:52 – Updated: 2026-03-04 14:11
VLAI
Title
Lack of TLS certificate validation when connecting Arc to a Guardian or CMC, in Arc before v2.2.0
Summary
The server certificate was not verified when an Arc agent connected to a Guardian or CMC.
A malicious actor could perform a man-in-the-middle attack and intercept the communication between the Arc agent and the Guardian or CMC. This could result in theft of the client token and sensitive information (such as assets and alerts), impersonation of the server, or injection of spoofed data (such as false asset information or vulnerabilities) into the Guardian or CMC.

CVE-2025-42611 (GCVE-0-2025-42611)
Vulnerability from cvelistv5 – Published: 2026-05-05 10:58 – Updated: 2026-05-05 12:49

Title
Improper certificate validation in multiple RouterOS services
Summary
RouterOS provides various services that rely on correct
verification of client and server certificates to secure confidentiality and
integrity of communications. This includes OpenVPN, CAPsMAN, Dot1x (802.1X),
among others.
The vulnerability lies in shared certificate validation
logic which uses the system certificate store that is shared and equally
trusted by all system services. This causes confusion of scope, allowing any
certificate authority present in the system-wide trust store to be trusted in
any context (with some exceptions), allowing partial or full authentication
bypass in CAPsMAN, OpenVPN, Dot1X and potentially others.
Severity
6.5 (Medium)
CWE
- CWE-295 - Improper certificate validation

CVE-2025-4575 (GCVE-0-2025-4575)

Title
The x509 application adds trusted use instead of rejected use
Summary
Issue summary: Use of -addreject option with the openssl x509 application adds
a trusted use instead of a rejected use for a certificate.
Impact summary: If a user intends to make a trusted certificate rejected for
a particular use it will be instead marked as trusted for that use.
A copy & paste error during minor refactoring of the code introduced this
issue in the OpenSSL 3.5 version. If, for example, a trusted CA certificate
should be trusted only for the purpose of authenticating TLS servers but not
for CMS signature verification and the CMS signature verification is intended
to be marked as rejected with the -addreject option, the resulting CA
certificate will be trusted for CMS signature verification purpose instead.
Only users which use the trusted certificate format who use the openssl x509
command line application to add rejected uses are affected by this issue.
The issues affecting only the command line application are considered to
be Low severity.
The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this
issue.
OpenSSL 3.4, 3.3, 3.2, 3.1, 3.0, 1.1.1 and 1.0.2 are also not affected by this
issue.
Severity
No CVSS data available.

Title
JRuby-OpenSSL has hostname verification disabled by default
Summary
JRuby-OpenSSL is an add-on gem for JRuby that emulates the Ruby OpenSSL native library. Starting in JRuby-OpenSSL version 0.12.1 and prior to version 0.15.4 (corresponding to JRuby versions starting in 9.3.4.0 prior to 9.4.12.1 and 10.0.0.0 prior to 10.0.0.1), when verifying SSL certificates, JRuby-OpenSSL does not verify that the hostname presented in the certificate matches the one the user tries to connect to. This means a man-in-the-middle could just present any valid cert for a completely different domain they own, and JRuby would accept the cert. Anybody using JRuby to make requests of external APIs, or scraping the web, that depends on https to connect securely. JRuby-OpenSSL version 0.15.4 contains a fix for the issue. This fix is included in JRuby versions 10.0.0.1 and 9.4.12.1.

This means a man-in-the-middle could just present any valid cert for a completely different domain they own, and JRuby would accept the cert. Anybody using JRuby to make requests of external APIs, or scraping the web, that depends on https to connect securely. JRuby-OpenSSL version 0.15.4 contains a fix for the issue. This fix is included in JRuby versions 10.0.0.1 and 9.4.12.1."

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.
