Siemens Security Alert: TeleControl Server Vulnerability Sparks Remote Code Concerns!
Siemens’ TeleControl Server is under siege! A vulnerability allows remote attackers to send malicious objects and execute arbitrary code. Update those servers to V3.1.2.1 or later, and maybe restrict access to trusted IPs. In short, if your server starts acting like a rebellious teenager, it’s time for a security upgrade!

Hot Take:
In a move that’s sure to thrill cybersecurity thrill-seekers and keep Siemens’ tech support staff busier than a one-armed juggler, CISA is stepping away from updating security advisories for Siemens products. It’s like the digital version of handing over the keys to the kingdom, but forgetting to change the locks. Now, if you want to know if your Siemens gadget is vulnerable, you better bookmark their ProductCERT Security Advisories faster than you can say ‘deserialization of untrusted data.’ Happy scrolling!
Key Points:
- CISA will no longer update ICS security advisories for Siemens after the initial advisory.
- The vulnerability involves deserialization of untrusted data, allowing remote code execution.
- Various Siemens TeleControl Server Basic versions are affected.
- Siemens recommends updating to version V3.1.2.1 or later.
- No known public exploitation targeting this vulnerability has been reported yet.
