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

Description The issue is related to the Simple Network Management Protocol (SNMP) module, which allows remote attackers to cause a denial of service (process reload) via a request for an unspecified MIB. This is due to improper processing of SNMP requests for certain MIBs. An attacker could exploit this by sending an SNMP request for certain MIB objects, allowing them to cause a reload of the SNMP process on an affected device. The attacker must authenticate to the targeted device to exploit this issue.

Recommendations To resolve the issue, update to a version of Cisco IOS XR Software that includes the fix for this problem. As a temporary workaround, consider restricting access to the SNMP module to minimize the risk of exploitation.
