An attacker could exploit this vulnerability by attempting to send traffic to an affected device. A successful exploit could allow the attacker to bypass an ingress ACL that is applied on the management interface of the affected device.", "affected": [ { "vendor": "Cisco", "product": "Cisco IOS XR Software", "defaultStatus": "unknown", "versions": [ { "version": "6.6.1", "status": "affected" }, { "version": "6.5.3", "status": "affected" }, { "version": "7.0.1", "status": "affected" }, { "version": "6.6.11", "status": "affected" }, { "version": "6.5.1", "status": "affected" }, { "version": "6.5.2", "status": "affected" }, { "version": "6.6.2", "status": "affected" }, { "version": "6.6.12", "status": "affected" }, { "version": "6.6.25", "status": "affected" }, { "version": "7.1.1", "status": "affected" }, { "version": "7.0.90", "status": "affected" }, { "version": "6.6.3", "status": "affected" }, { "version": "7.0.2", "status": "affected" }, { "version": "7.1.2", "status": "affected" }, { "version": "7.2.1", "status": "affected" }, { "version": "7.0.11", "status": "affected" }, { "version": "7.0.12", "status": "affected" }, { "version": "7.0.14", "status": "affected" }, { "version": "6.6.4", "status": "affected" }, { "version": "7.2.12", "status": "affected" }, { "version": "7.3.1", "status": "affected" }, { "version": "7.4.1", "status": "affected" }, { "version": "7.2.2", "status": "affected" }, { "version": "7.3.15", "status": "affected" }, { "version": "7.3.16", "status": "affected" }, { "version": "7.4.15", "status": "affected" }, { "version": "7.3.2", "status": "affected" }, { "version": "7.5.1", "status": "affected" }, { "version": "7.4.16", "status": "affected" }, { "version": "7.3.27", "status": "affected" }, { "version": "7.6.1", "status": "affected" }, { "version": "7.5.2", "status": "affected" }, { "version": "7.8.1", "status": "affected" }, { "version": "7.6.15", "status": "affected" }, { "version": "7.5.12", "status": "affected" }, { "version": "7.8.12", "status": "affected" }, { "version": "7.3.4", "status": "affected" }, { "version": "7.3.3", "status": "affected" }, { "version": "7.4.2", "status": "affected" }, { "version": "7.7.1", "status": "affected" }, { "version": "7.6.2", "status": "affected" }, { "version": "7.5.3", "status": "affected" }, { "version": "7.7.2", "status": "affected" }, { "version": "7.9.1", "status": "affected" }, { "version": "7.10.1", "status": "affected" }, { "version": "7.8.2", "status": "affected" }, { "version": "7.5.4", "status": "affected" }, { "version": "7.8.22", "status": "affected" }, { "version": "7.7.21", "status": "affected" }, { "version": "7.9.2", "status": "affected" }, { "version": "7.3.5", "status": "affected" }, { "version": "7.5.5", "status": "affected" }, { "version": "7.11.1", "status": "affected" }, { "version": "7.10.2", "status": "affected" }, { "version": "24.1.1", "status": "affected" }, { "version": "7.3.6", "status": "affected" }, { "version": "7.5.52", "status": "affected" }, { "version": "7.11.2", "status": "affected" }, { "version": "24.2.1", "status": "affected" }, { "version": "24.1.2", "status": "affected" }, { "version": "24.2.11", "status": "affected" }, { "version": "24.3.1", "status": "affected" }, { "version": "24.4.1", "status": "affected" }, { "version": "24.2.2", "status": "affected" }, { "version": "7.11.21", "status": "affected" }, { "version": "24.2.20", "status": "affected" }, { "version": "24.3.2", "status": "affected" }, { "version": "25.1.1", "status": "affected" }, { "version": "24.4.2", "status": "affected" }, { "version": "24.3.20", "status": "affected" }, { "version": "25.1.2", "status": "affected" }, { "version": "24.3.30", "status": "affected" }, { "version": "24.4.30", "status": "affected" }, { "version": "24.2.21", "status": "affected" } ] } ] } } }
