Synopsis

The remote VxWorks device is potentially affected by multiple remote code execution and denial-of-service vulnerabilities.

Description

According to its self-reported version, the remote device is potentially affected by multiple Wind River VxWorks remote code execution and denial-of-service vulnerabilities in the IPnet TCP/IP stack. An unauthenticated, remote, attacker could leverage these vulnerabilities to gain full access to the affected device or to cause the device to become unresponsive.

Note that Nessus has not checked for the presence of the patch so this finding may be a false positive.

Solution

Contact the device vendor to obtain the appropriate update
