Treck TCP/IP stack multiple vulnerabilities. (Ripple20)

Question

C1: Treck TCP/IP stack multiple vulnerabilities. (Ripple20) Synopsis: The Treck network stack used by the remote host is affected by multiple vulnerabilities. Description: This plugin detects the usage of the Treck TCP/IP stack by the host thereby indicating that it could be potentially vulnerable to the Ripple20 vulnerabilities. Patches are being slowly rolled out by vendors and we will release plugins for patches as they are released by the vendors. In the interim, if you have applied the patches from the vendor for the Ripple20 vulnerabilities on this host, please recast the severity of this plugin. Note: This plugin requires ICMP traffic to be unblocked between the scanner and the host Affected IP Addresses: 4.240.104.30 Plugin Output: Host: 4.240.104.30 Output: Detected Treck TCP\IP network stack. Remediation: Apply the relevant patches as they become available.

Answer 1

Hi Amit Kumar,

The Ripple20 vulnerabilities include multiple flaws such as improper input validation, buffer overflows, and access control weaknesses. These issues can potentially allow attackers to execute code remotely or disrupt services. The affected components are embedded in many IoT and industrial devices, which makes patching more complex as vendors must release updates for their specific products.

The recommended remediation is to apply vendor-provided patches as soon as they become available. Since Treck itself has issued fixes, many device manufacturers are gradually rolling out updates. Please check with the vendor of the affected device (associated with IP 4.240.104.30) to confirm whether a patch has been released and apply it immediately. If a patch is not yet available, consider implementing compensating controls such as restricting ICMP traffic, segmenting the device from untrusted networks, and monitoring for unusual activity.

Additionally, CISA has published guidance on Ripple20, including baseline mitigations such as disabling unnecessary services, applying strict firewall rules, and ensuring devices are not directly exposed to the internet. These steps can significantly reduce the risk while awaiting vendor patches.

In summary, the key actions are: verify vendor patch availability, apply updates promptly, and implement network-level mitigations to reduce exposure. I recommend documenting the remediation steps taken so that the severity of the plugin can be recast once patches are applied.

Answer 3

The Ripple20 vulnerabilities affect the Treck TCP/IP stack, which is used by various devices and systems. If a host is using this stack, it may be vulnerable to multiple security issues that could be exploited by attackers. It is important to apply patches provided by the vendors as they become available to mitigate these vulnerabilities. Additionally, ensuring that ICMP traffic is unblocked between the scanner and the host is necessary for detection and remediation processes.
