The C:\\Windows\\Temp~nsu.tmp\\Au_.exe file is automatically launched as SYSTEM when the system reboots or when a standard user runs an MSI repair using Splashtop Streamer’s Windows Installer. Since the C:\\Windows\\Temp~nsu.tmp folder inherits permissions from C:\\Windows\\Temp and Au_.exe is susceptible to DLL hijacking, standard users can write a malicious DLL to it and elevate their privileges.","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-379"],"references":["https://github.com/mandiant/Vulnerability-Disclosures/blob/master/2023/MNDT-2023-0015.md","https://github.com/mandiant/Vulnerability-Disclosures/blob/master/2023/MNDT-2023-0015.md"],"products":["splashtop:mirroring360_receiver","splashtop:mirroring360_sender","splashtop:splashtop","splashtop:splashtop_for_rmm","splashtop:streamer"],"source":"nvd","synced_at":"2026-10-19T21:44:57.175229480+00:00"},"epss":{"cve":"CVE-2023-3181","score":0.00179,"percentile":0.07476,"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).
