Researchers discovered 19 new zero-day vulnerabilities in a TCP/IP software library developed by Treck. Dubbed Ripple20, the batch includes CVE-2020-11901, which has the potential to allow control of an internet-connected device. Update June 24, 2020: We’ve updated the Identifying affected systems section to include an additional link to a newly released Tenable plugin as well as additional information for our tenable.ot customers.

CVE-2020-11896, CVE-2020-11897, CVE-2020-11901: Ripple20 Zero-Day Vulnerabilities in Treck TCP/IP Libraries Disclosed

The Treck TCP/IP stack before 6.0.1.66 allows Remote Code execution via a single invalid DNS response.

The version of ArubaOS-Switch installed on the remote host is affected by multiple vulnerabilities in the Treck IP stack implementation. The vulnerabilities are collectively known as Ripple20, and can result in remote code execution, denial of service (DoS), and information disclosure by remote, unauthenticated attackers.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version, Cisco ASR and Virtual Packet Core StarOS software is affected by multiple vulnerabilities in the Treck IP stack implementation. The vulnerabilities are collectively known as Ripple20, and can result in remote code execution, denial of service (DoS), and information disclosure by remote, unauthenticated attackers.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.

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
