Siemens SIPROTEC 5 Security Flaw: A Comedy of GET Requests and Sensitive Data!
Siemens product vulnerabilities are going on a solo tour! CISA will stop updating ICS security advisories for Siemens products. To catch the latest, check Siemens’ ProductCERT Security Advisories. Remember, even vulnerabilities need a little independence now and then!

Hot Take:
Looks like Siemens has decided to leave the ICS security advisory updates to their own devices (pun intended). CISA’s stepping back, so Siemens’ ProductCERT Security Advisories will now be the new gossip column for SIPROTEC 5 vulnerabilities. It’s like trading your cybersecurity updates for a secret recipe only the chef knows. Bon appétit!
Key Points:
- Siemens SIPROTEC 5 products have a vulnerability involving GET request methods with sensitive query strings.
- Successful exploitation could lead to unauthorized access through sensitive session data retrieval.
- Siemens is working on fixes; meanwhile, it recommends robust network security measures.
- CISA shifts focus, leaving ongoing updates to Siemens’ ProductCERT Advisories.
- No known public exploitation of this vulnerability has been reported yet.
