CVE-2015-0776

Name of the Vulnerable Software and Affected Versions Cisco IOS XR version 5.0.1

Description The issue is related to resource management errors in the telnetd subcomponent of the Cisco IOS operating system. It can be exploited by a remote attacker using a specially crafted telnet packet, potentially leading to a denial of service, causing the device to reload.

Recommendations For Cisco IOS XR version 5.0.1, consider restricting access to the telnetd service until a patch is available to prevent potential exploitation. As a temporary workaround, limiting the exposure of the device to untrusted networks may also help minimize the risk of a denial of service attack.
