Siemens Security Alert: RUGGEDCOM APE 1808 Vulnerabilities Revealed!

Hot Take:

Looks like Siemens is handing off their security babysitting duties to Fortinet. Let’s hope Fortinet has packed enough diapers because these vulnerabilities are messy!

Key Points:

• CISA will stop updating ICS security advisories for Siemens product vulnerabilities as of January 10, 2023.
• Three main vulnerabilities: Stack-based Buffer Overflow, Use of Password Hash With Insufficient Computational Effort, Cross-site Scripting.
• The affected product is Siemens RUGGEDCOM APE 1808 with Fortinet NGFW.
• Vulnerabilities could allow attackers to execute unauthorized code or commands and decrypt backup files.
• Siemens recommends contacting customer support for patches and protecting network access with appropriate mechanisms.

Siemens Says Goodbye to Babysitting

So, Siemens decided it’s about time Fortinet cleaned up its own mess. As of January 10, 2023, CISA will no longer be sending out security advisories for Siemens products. If you need the latest dirt on Siemens vulnerabilities, you’ll have to take a trip to Siemens’ ProductCERT Security Advisories. What’s next, Siemens? A “How to Secure Your Own Product” handbook?

The Triple Threat: Buffer Overflow, Weak Passwords, and Cross-site Scripting

Here’s the spicy part: Siemens’ RUGGEDCOM APE 1808 with Fortinet NGFW is the star in this vulnerability soap opera. The vulnerabilities include a stack-based buffer overflow, use of password hash with insufficient computational effort, and cross-site scripting. So, you know, just a regular Tuesday in cybersecurity land. These flaws could let cyber villains execute unauthorized commands and decrypt backup files—basically, the hacker equivalent of finding a treasure chest full of gold.

Risk Evaluation: The Cyber Bouncer’s Nightmare

Successful exploitation of these vulnerabilities could allow an attacker to sneak in unauthorized code or commands via specially crafted CLI commands. The vulnerabilities affect a wide range of Fortinet FortiOS and FortiProxy versions, making it a buffet for potential attackers. In simple terms, it’s like giving hackers the keys to your secret candy stash.

Technical Details: The Nerdy Bits

Affected products include all versions of Siemens RUGGEDCOM APE1808 with Fortinet NGFW. The vulnerabilities are spread across various versions of FortiOS and FortiProxy. For example, CVE-2023-46720 is a stack-based buffer overflow in Fortinet FortiOS, affecting versions from 7.4.0 to 6.0.18. Meanwhile, CVE-2024-21754 and CVE-2024-23111 are vulnerabilities related to insufficient computational effort in password hashing, affecting multiple FortiOS and FortiProxy versions. It’s like a cybersecurity horror movie with sequels you never asked for.

Background: Siemens’ Global Footprint

These vulnerabilities could impact critical infrastructure sectors such as Communications, Critical Manufacturing, Energy, and Transportation. So, if you ever wanted to know what it feels like to have your power grid hacked, now’s your chance! Siemens, headquartered in Germany, reported these vulnerabilities to CISA, proving that even the big guys aren’t immune to cyber woes.

Mitigations: The Cybersecurity Band-Aids

Siemens suggests contacting customer support for patches and updates. As a general rule, they recommend protecting network access to devices using appropriate mechanisms. So, basically, lock your doors, close your windows, and maybe throw in a security camera or two. Siemens also advises configuring your environment according to their operational guidelines and following product manuals. Remember, folks, reading the manual isn’t just for nerds!

For more detailed information, you can visit Siemens’ industrial security webpage or the associated Siemens security advisory SSA-698820.

CISA’s Defensive Playbook

CISA also has some sage advice: minimize network exposure, keep control system devices off the internet, and use firewalls. When remote access is necessary, secure it with VPNs—just make sure your VPN is up-to-date and the connected devices aren’t compromised. CISA also reminds organizations to perform proper impact analysis and risk assessment before implementing any defensive measures.

For those who want to go the extra mile, CISA provides a treasure trove of cybersecurity strategies and best practices on their ICS webpage. If you suspect any malicious activity, report it to CISA for tracking and correlation against other incidents.

Conclusion: No Public Exploitation Yet, But Stay Vigilant

As of now, there’s no known public exploitation specifically targeting these vulnerabilities. But
