The client update process is executed after a successful VPN connection is established.\r\n\r This vulnerability exists because improper permissions are assigned to a temporary directory that is created during the update process. An attacker could exploit this vulnerability by abusing a specific function of the Windows installer process. A successful exploit could allow the attacker to execute code with SYSTEM privileges.","state":0,"publishedAt":"2023-06-28T00:00:00+00:00","modifiedAt":"2026-10-08T21:14:03.615+00:00","affected":[{"ecosystem":"Vendor product","name":"Cisco Secure Client","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Cisco\",\n                    \"product\": \"Cisco Secure Client\",\n                    \"versions\": [\n                        {\n                            \"version\": \"4.9.00086\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.01095\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.02028\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.03047\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.03049\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.04043\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.04053\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.05042\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.9.06037\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.00093\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.01075\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.02086\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.03104\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.04065\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.04071\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.05085\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.05095\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.05111\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.06079\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"4.10.06090\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"5.0.00238\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"5.0.00529\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"5.0.00556\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"5.0.01242\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ac-csc-privesc-wx4U4Kw"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-20178","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-20178","identifiers":["CVE-2023-20178"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
