AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions IP Infusion ZebOS versions 7.10.6 and earlier

Description The issue allows remote attackers to cause a denial of service by sending crafted BGP update messages containing a malformed attribute. This is related to the BGP daemon (bgpd) in IP Infusion ZebOS.

Recommendations For IP Infusion ZebOS versions 7.10.6 and earlier, consider restricting access to the BGP daemon to minimize the risk of exploitation until a patch is available. As a temporary workaround, network administrators may need to implement additional filtering or validation of BGP update messages to prevent the inclusion of malformed attributes.
