An attacker could exploit this vulnerability by sending a crafted serialized Java object to the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the device and elevate privileges to root.\r\nNote: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced.", "affected": [ { "vendor": "Cisco", "product": "Cisco Secure Firewall Management Center (FMC)", "defaultStatus": "unknown", "versions": [ { "version": "7.0.0", "status": "affected" }, { "version": "7.0.0.1", "status": "affected" }, { "version": "7.0.1", "status": "affected" }, { "version": "7.1.0", "status": "affected" }, { "version": "6.4.0.13", "status": "affected" }, { "version": "7.0.1.1", "status": "affected" }, { "version": "6.4.0.14", "status": "affected" }, { "version": "7.1.0.1", "status": "affected" }, { "version": "7.0.2", "status": "affected" }, { "version": "6.4.0.15", "status": "affected" }, { "version": "7.2.0", "status": "affected" }, { "version": "7.0.2.1", "status": "affected" }, { "version": "7.0.3", "status": "affected" }, { "version": "7.1.0.2", "status": "affected" }, { "version": "7.2.0.1", "status": "affected" }, { "version": "7.0.4", "status": "affected" }, { "version": "7.2.1", "status": "affected" }, { "version": "7.0.5", "status": "affected" }, { "version": "6.4.0.16", "status": "affected" }, { "version": "7.3.0", "status": "affected" }, { "version": "7.2.2", "status": "affected" }, { "version": "7.3.1", "status": "affected" }, { "version": "7.2.3", "status": "affected" }, { "version": "7.1.0.3", "status": "affected" }, { "version": "7.2.3.1", "status": "affected" }, { "version": "7.2.4", "status": "affected" }, { "version": "7.0.6", "status": "affected" }, { "version": "7.2.4.1", "status": "affected" }, { "version": "7.2.5", "status": "affected" }, { "version": "7.3.1.1", "status": "affected" }, { "version": "7.4.0", "status": "affected" }, { "version": "6.4.0.17", "status": "affected" }, { "version": "7.0.6.1", "status": "affected" }, { "version": "7.2.5.1", "status": "affected" }, { "version": "7.4.1", "status": "affected" }, { "version": "7.2.6", "status": "affected" }, { "version": "7.4.1.1", "status": "affected" }, { "version": "7.0.6.2", "status": "affected" }, { "version": "6.4.0.18", "status": "affected" }, { "version": "7.2.7", "status": "affected" }, { "version": "7.2.5.2", "status": "affected" }, { "version": "7.3.1.2", "status": "affected" }, { "version": "7.2.8", "status": "affected" }, { "version": "7.6.0", "status": "affected" }, { "version": "7.4.2", "status": "affected" }, { "version": "7.2.8.1", "status": "affected" }, { "version": "7.0.6.3", "status": "affected" }, { "version": "7.4.2.1", "status": "affected" }, { "version": "7.2.9", "status": "affected" }, { "version": "7.0.7", "status": "affected" }, { "version": "7.7.0", "status": "affected" }, { "version": "7.4.2.2", "status": "affected" }, { "version": "7.2.10", "status": "affected" }, { "version": "7.6.1", "status": "affected" }, { "version": "7.4.2.3", "status": "affected" }, { "version": "7.0.8", "status": "affected" }, { "version": "7.6.2", "status": "affected" }, { "version": "7.7.10", "status": "affected" }, { "version": "7.2.10.1", "status": "affected" }, { "version": "7.0.8.1", "status": "affected" }, { "version": "7.6.2.1", "status": "affected" }, { "version": "7.2.10.2", "status": "affected" }, { "version": "7.7.10.1", "status": "affected" }, { "version": "7.4.2.4", "status": "affected" }, { "version": "7.4.3", "status": "affected" }, { "version": "7.7.11", "status": "affected" }, { "version": "7.6.4", "status": "affected" }, { "version": "10.0.0", "status": "affected" }, { "version": "7.4.4", "status": "affected" }, { "version": "7.4.5", "status": "affected" } ] } ] } } }
