Siemens Security SNAFU: Gridscale X Prepay Vulnerabilities Exposed!
CISA will stop updating ICS security advisories for Siemens product vulnerabilities beyond the initial advisory from January 10, 2023. For the latest on Siemens product vulnerabilities, rely on Siemens’ ProductCERT Security Advisories. So, if you want to keep your grid in check, Siemens has got your back—just not through CISA!

Hot Take:
Looks like Siemens is pulling the old “drop the mic and walk away” on updating ICS security advisories. As the cybersecurity world’s version of ghosting, CISA is leaving Siemens to handle their own vulnerabilities. But fear not, Siemens’ ProductCERT Security Advisories is ready to pick up the slack, like a loyal sidekick ready to save the day. It’s a classic tale of ‘I got 99 problems but updating ain’t one!’
Key Points:
- Siemens’ Gridscale X Prepay product has vulnerabilities that can be exploited remotely.
- Two main vulnerabilities: user enumeration and capture-replay of authentication tokens.
- Vulnerabilities could allow attackers to bypass user sessions and enumerate valid usernames.
- CISA will not update ICS security advisories for Siemens beyond the initial advisory.
- Siemens and CISA provide mitigation strategies to reduce vulnerability risks.
