Twenty-one security flaws dubbed Sierra:21 affect over 86,000 Sierra Wireless AirLink routers, risking credential theft, device control, and botnet use in sectors like energy and healthcare. Fixes have been released for some components, but TinyXML remains unpatched. The vulnerabilities threaten critical infrastructure with various cyber threats.
### Meeting Takeaways: Cyber Threat / Vulnerability Update
**Date:** December 6, 2023
**Topic:** Discovery of Security Flaws in Sierra Wireless AirLink Routers
**Key Points:**
1. **Vulnerabilities Identified:** A total of 21 security flaws were found in Sierra Wireless AirLink cellular routers and open-source components such as TinyXML and OpenNDS, collectively referred to as Sierra:21.
2. **Devices at Risk:** Over 86,000 devices are affected, impacting critical sectors including energy, healthcare, waste management, retail, emergency services, and vehicle tracking, predominantly located in the United States, Canada, Australia, France, and Thailand.
3. **Threat Landscape:** Exploitation of these vulnerabilities could lead to credential theft, unauthorized control of routers, persistent device compromise, and serves as initial access points for attackers into critical networks.
4. **Severity Ratings:** Out of the 21 vulnerabilities, 1 is critical, 9 are high, and 11 are medium severity. They allow for remote code execution (RCE), cross-site scripting (XSS), denial-of-service (DoS), unauthorized access, and authentication bypass.
5. **Potential Exploits:** Attackers could use these flaws to steal credentials, inject malware, execute AitM attacks, and enable botnets for DDoS attacks or other malicious activities.
6. **Patches Released:** Fixes are available in ALEOS firmware versions 4.17.0 or 4.9.9, and OpenNDS version 10.1.3. However, TinyXML is not actively maintained, requiring other vendors to address its associated issues.
7. **Cyber Threat Actors:** State-sponsored groups and cybercriminals might exploit these vulnerabilities for espionage, network disruption, lateral movement, residential proxies, or recruiting devices into botnets.
**Recommendations:**
– Organizations using affected devices must promptly apply the released patches.
– Monitor threat intelligence for updates and signs of exploitation attempts.
