An attacker could exploit this vulnerability by sending a series of crafted IPC messages to a local socket. A successful exploit could allow the attacker to perform limited file write operations on the filesystem with SYSTEM or root privileges.\r\nAlthough this vulnerability affects the Secure Firewall Posture module in Cisco Secure Client on Windows, macOS, and Linux operating systems, this vulnerability could be used to obtain full root privileges on macOS and Linux. For that reason Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates.", "affected": [ { "vendor": "Cisco", "product": "Cisco Secure Client", "defaultStatus": "unknown", "versions": [ { "version": "4.9.00086", "status": "affected" }, { "version": "4.9.01095", "status": "affected" }, { "version": "4.9.02028", "status": "affected" }, { "version": "4.9.03047", "status": "affected" }, { "version": "4.9.03049", "status": "affected" }, { "version": "4.9.04043", "status": "affected" }, { "version": "4.9.04053", "status": "affected" }, { "version": "4.9.05042", "status": "affected" }, { "version": "4.9.06037", "status": "affected" }, { "version": "4.10.00093", "status": "affected" }, { "version": "4.10.01075", "status": "affected" }, { "version": "4.10.02086", "status": "affected" }, { "version": "4.10.03104", "status": "affected" }, { "version": "4.10.04065", "status": "affected" }, { "version": "4.10.04071", "status": "affected" }, { "version": "4.10.05085", "status": "affected" }, { "version": "4.10.05095", "status": "affected" }, { "version": "5.0.00238", "status": "affected" }, { "version": "4.10.05111", "status": "affected" }, { "version": "5.0.00529", "status": "affected" }, { "version": "5.0.00556", "status": "affected" }, { "version": "4.10.06079", "status": "affected" }, { "version": "5.0.01242", "status": "affected" }, { "version": "4.10.06090", "status": "affected" }, { "version": "5.0.02075", "status": "affected" }, { "version": "4.10.07061", "status": "affected" }, { "version": "5.0.03072", "status": "affected" }, { "version": "4.10.07062", "status": "affected" }, { "version": "5.0.03076", "status": "affected" }, { "version": "5.0.04032", "status": "affected" }, { "version": "4.10.07073", "status": "affected" }, { "version": "5.0.05040", "status": "affected" }, { "version": "5.1.0.136", "status": "affected" }, { "version": "5.1.1.42", "status": "affected" }, { "version": "4.10.08025", "status": "affected" }, { "version": "5.1.2.42", "status": "affected" }, { "version": "4.10.08029", "status": "affected" }, { "version": "5.1.3.62", "status": "affected" }, { "version": "5.1.4.74", "status": "affected" }, { "version": "5.1.5.65", "status": "affected" }, { "version": "5.1.6.103", "status": "affected" }, { "version": "5.1.7.80", "status": "affected" }, { "version": "5.1.8.105", "status": "affected" }, { "version": "5.1.8.122", "status": "affected" }, { "version": "5.1.9.113", "status": "affected" }, { "version": "5.1.10.233", "status": "affected" }, { "version": "5.1.11.388", "status": "affected" }, { "version": "5.1.12.146", "status": "affected" }, { "version": "5.1.13.117", "status": "affected" }, { "version": "5.1.13.177", "status": "affected" }, { "version": "5.1.14.145", "status": "affected" }, { "version": "5.1.15.287", "status": "affected" }, { "version": "5.1.16.194", "status": "affected" }, { "version": "5.1.17.3382", "status": "affected" }, { "version": "5.1.17.3394", "status": "affected" }, { "version": "5.1.18.314", "status": "affected" }, { "version": "5.1.19.1862", "status": "affected" } ] } ] } } }
