{"cve":"CVE-2023-3972","nvd":{"published":"2023-11-01T16:15:08.517","modified":"2026-06-17T06:15:32.367","status":"Modified","description":"A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-668","CWE-379"],"references":["https://access.redhat.com/errata/RHSA-2023:6264","https://access.redhat.com/errata/RHSA-2023:6282","https://access.redhat.com/errata/RHSA-2023:6283","https://access.redhat.com/errata/RHSA-2023:6284","https://access.redhat.com/errata/RHSA-2023:6795"],"products":["redhat:enterprise_linux","redhat:enterprise_linux_aus","redhat:enterprise_linux_desktop","redhat:enterprise_linux_eus","redhat:enterprise_linux_for_arm_64","redhat:enterprise_linux_for_arm_64_eus","redhat:enterprise_linux_for_ibm_z_systems","redhat:enterprise_linux_for_ibm_z_systems_eus","redhat:enterprise_linux_for_power_big_endian","redhat:enterprise_linux_for_power_little_endian","redhat:enterprise_linux_for_power_little_endian_eus","redhat:enterprise_linux_for_scientific_computing","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions","redhat:enterprise_linux_server_tus","redhat:enterprise_linux_server_update_services_for_sap_solutions","redhat:enterprise_linux_update_services_for_sap_solutions","redhat:insights-client"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-3972","score":0.00269,"percentile":0.1913,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
