Name of the Vulnerable Software and Affected Versions Contiki version 3.0
Description The issue is related to a buffer overflow in the Telnet service, which can be exploited by remote attackers to cause a denial of service. This occurs because the ls command is mishandled when a directory contains many files with long names.
Recommendations For Contiki version 3.0, consider disabling the Telnet service until a patch is available to prevent potential denial of service attacks. Restrict access to directories with many files to minimize the risk of exploitation. Avoid using the ls command in the Telnet service for directories with long file names until the issue is resolved.
