CVE-2013-1234

Name of the Vulnerable Software and Affected Versions Cisco IOS XR Software (affected versions not specified)

Description The issue is related to the SNMP module in Cisco IOS XR, which allows remote authenticated users to cause a denial of service by sending crafted SNMP packets. This is due to improper processing of these packets. An attacker would need access to a trusted internal network and must authenticate to the targeted device to exploit this issue. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.

Recommendations To resolve the issue, customers are advised to review the bug reports in the "Vendor Announcements" section for a current list of affected versions and apply available software updates. As a temporary workaround, consider restricting access to the SNMP module to minimize the risk of exploitation. Avoid using the SNMP module until the issue is resolved with a software update.
