To exploit this vulnerability, the attacker must have Administrator-level credentials with read-write privileges on an affected device.\r\n\r\nThis vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by submitting a series of crafted CLI commands. A successful exploit could allow the attacker to escape the restricted shell and gain root privileges on the underlying operating system of the affected device.\r\nNote: Cisco Expressway Series refers to Cisco Expressway Control (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices.", "affected": [ { "vendor": "Cisco", "product": "Cisco TelePresence Video Communication Server (VCS) Expressway", "defaultStatus": "unknown", "versions": [ { "version": "X8.11.2", "status": "affected" }, { "version": "X8.6", "status": "affected" }, { "version": "X8.11.3", "status": "affected" }, { "version": "X8.2.2", "status": "affected" }, { "version": "X8.8.3", "status": "affected" }, { "version": "X8.11.0", "status": "affected" }, { "version": "X12.5.2", "status": "affected" }, { "version": "X8.1.1", "status": "affected" }, { "version": "X8.9", "status": "affected" }, { "version": "X12.5.1", "status": "affected" }, { "version": "X12.5.6", "status": "affected" }, { "version": "X8.7.3", "status": "affected" }, { "version": "X12.6.0", "status": "affected" }, { "version": "X8.11.1", "status": "affected" }, { "version": "X8.5", "status": "affected" }, { "version": "X8.9.1", "status": "affected" }, { "version": "X8.10.2", "status": "affected" }, { "version": "X8.8.2", "status": "affected" }, { "version": "X8.5.3", "status": "affected" }, { "version": "X8.1", "status": "affected" }, { "version": "X8.9.2", "status": "affected" }, { "version": "X8.11.4", "status": "affected" }, { "version": "X12.5.4", "status": "affected" }, { "version": "X8.8.1", "status": "affected" }, { "version": "X8.2.1", "status": "affected" }, { "version": "X8.5.1", "status": "affected" }, { "version": "X8.6.1", "status": "affected" }, { "version": "X8.1.2", "status": "affected" }, { "version": "X8.8", "status": "affected" }, { "version": "X8.10.0", "status": "affected" }, { "version": "X12.5.3", "status": "affected" }, { "version": "X8.10.1", "status": "affected" }, { "version": "X12.5.7", "status": "affected" }, { "version": "X8.10.3", "status": "affected" }, { "version": "X8.7.1", "status": "affected" }, { "version": "X8.2", "status": "affected" }, { "version": "X12.5.8", "status": "affected" }, { "version": "X8.7", "status": "affected" }, { "version": "X8.5.2", "status": "affected" }, { "version": "X12.5.9", "status": "affected" }, { "version": "X12.5.0", "status": "affected" }, { "version": "X8.10.4", "status": "affected" }, { "version": "X8.7.2", "status": "affected" }, { "version": "X12.5.5", "status": "affected" }, { "version": "X12.6.1", "status": "affected" }, { "version": "X12.6.2", "status": "affected" }, { "version": "X12.6.3", "status": "affected" }, { "version": "X12.6.4", "status": "affected" }, { "version": "X12.7.0", "status": "affected" }, { "version": "X12.7.1", "status": "affected" }, { "version": "X14.0.0", "status": "affected" }, { "version": "X14.0.1", "status": "affected" }, { "version": "X14.0.2", "status": "affected" }, { "version": "X14.0.3", "status": "affected" }, { "version": "X14.0.4", "status": "affected" }, { "version": "X14.0.5", "status": "affected" }, { "version": "X14.0.6", "status": "affected" }, { "version": "X14.0.7", "status": "affected" }, { "version": "X14.0.8", "status": "affected" }, { "version": "X14.2.0", "status": "affected" }, { "version": "X14.0.9", "status": "affected" }, { "version": "X14.2.1", "status": "affected" }, { "version": "X14.2.2", "status": "affected" }, { "version": "X14.0.11", "status": "affected" }, { "version": "X14.2.5", "status": "affected" }, { "version": "X14.0.10", "status": "affected" }, { "version": "X14.2.6", "status": "affected" }, { "version": "X14.2.7", "status": "affected" }, { "version": "X14.3.0", "status": "affected" }, { "version": "X14.3.1", "status": "affected" }, { "version": "X14.3.2", "status": "affected" }, { "version": "X14.3.3", "status": "affected" }, { "version": "X15.0.0", "status": "affected" }, { "version": "X14.3.4", "status": "affected" }, { "version": "X14.3.5", "status": "affected" }, { "version": "X15.0.1", "status": "affected" }, { "version": "X15.0.2", "status": "affected" }, { "version": "X15.0.3", "status": "affected" }, { "version": "X14.3.6", "status": "affected" } ] } ] } } }
