Siemens SAML Security Flaw: Remote Hijacking Risk Looms Large
CISA advises that starting January 10, 2023, Siemens product vulnerabilities will only receive initial advisories. For the latest on these vulnerabilities, visit Siemens’ ProductCERT Security Advisories. Remember, nothing like a cryptographic signature vulnerability to make your heart skip a beat—especially when it involves the Mendix SAML Module.
Hot Take:
Looks like Siemens is throwing a party and forgot to lock the doors! With CISA passing the vulnerability hot potato back to Siemens, it’s up to the German engineering giants to keep their own backyard safe. Time to dust off those operational guidelines and make sure your networks are as impenetrable as a bratwurst on a vegan diet!
Key Points:
- Siemens Mendix SAML module is vulnerable to account hijacking via improper cryptographic signature verification.
- The vulnerability affects specific versions of Mendix SAML with a concerning CVSS score of 8.7.
- Unauthenticated remote attackers can exploit the vulnerability in certain SSO configurations.
- CISA will no longer update ICS advisories for Siemens products; users must check Siemens’ ProductCERT for updates.
- Siemens recommends network security measures and following operational guidelines to mitigate risks.
