The persistence of unpatched vulnerabilities in IoT routers and network tools poses a serious threat to industrial systems and internet infrastructure.
Cisco Talos recently revealed that several critical flaws in MC Technologies industrial routers and the GoCast BGP tool remain unresolved, even eight months after being disclosed to the vendors.
These security gaps, if exploited, could lead to unauthorized command execution, putting sensitive systems at risk.
Key Takeaway to Unpatched Vulnerabilities in IoT Routers:
- The lack of fixes for unpatched vulnerabilities in IoT routers and network tools highlights the urgent need for vendors to act quickly in addressing security flaws.
Details of the Unpatched Vulnerabilities
Vulnerabilities in MC Technologies Industrial Routers
Cisco Talos discovered four high-severity flaws in the MC LR router, an industrial device widely used in IoT and Industry 4.0 applications.
Key Findings:
- Affected Product: MC LR router, version 2.10.5.
- Nature of the Flaws: OS command injection vulnerabilities in the web interface.
- Exploitation Method: An attacker can exploit these vulnerabilities by sending a specially crafted HTTP request.
- Attack Requirement: The attacker must be authenticated to execute arbitrary commands.
Why This Matters
MC Technologies is a Germany-based company specializing in industrial and IoT solutions, including cellular modems and smart meter accessories.
Their products are widely used in critical industries. If these flaws are exploited, they could disrupt essential operations.
Critical Flaws in GoCast BGP Tool
Cisco Talos also identified three critical vulnerabilities in GoCast, an open-source tool for managing BGP route advertisements. Unlike the MC router flaws, these vulnerabilities do not require authentication.
Key Findings:
- Nature of the Flaws: OS command injection vulnerabilities.
- Exploitation Method: An unauthenticated attacker can trigger these flaws with a specially crafted HTTP request.
- Potential Impact: Attackers could use these vulnerabilities to control BGP route advertisements, potentially disrupting internet traffic routing.
Real-Life Example: The 2008 BGP Hijack
In 2008, a BGP misconfiguration caused Pakistan’s attempt to block YouTube locally to cascade globally, taking the site offline worldwide. If tools like GoCast are exploited, similar disruptions or targeted attacks could occur.
Cisco Talos’ Efforts and Vendor Response
Cisco Talos responsibly disclosed these flaws in March (MC Technologies) and April (GoCast). Despite multiple attempts, neither vendor has issued patches.
Timeline of Disclosure:
| Vendor | Date of Disclosure | Current Status |
|---|---|---|
| MC Technologies | March 2024 | No patches available |
| GoCast | April 2024 | No patches available |
Risks of Unpatched Vulnerabilities in IoT Routers
Unpatched vulnerabilities in IoT routers like MC LR can lead to:
- System Compromise: Attackers could execute commands to disrupt or control devices.
- Data Theft: Sensitive data may be exposed during an attack.
- Industrial Downtime: Exploitation in critical environments like manufacturing can result in costly downtime.
For GoCast, flaws in BGP route management can have wider repercussions:
- Internet Traffic Hijacking: Mismanaged routes could redirect traffic to attacker-controlled servers.
- Network Disruption: Entire regions could experience outages, similar to past BGP incidents.
The Need for Faster Vendor Response
Cisco’s revelations underscore a critical problem in cybersecurity: vendor delays in addressing reported flaws.
This isn’t the first time such negligence has been observed. In 2021, researchers found unpatched vulnerabilities in popular home routers, affecting millions of users. These cases show the importance of immediate action to protect users.
