During the add printer process, a local attacker can overwrite CNMurGE.dll and, if timed properly, the overwritten DLL will be loaded into a SYSTEM process resulting in escalation of privileges. This occurs because the driver drops a world-writable DLL into a CanonBJ %PROGRAMDATA% location that gets loaded by printisolationhost (a system process).","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-732"],"references":["http://packetstormsecurity.com/files/163795/Canon-TR150-Driver-3.71.2.10-Privilege-Escalation.html","https://defcon.org/html/defcon-29/dc-29-speakers.html#baines","https://raw.githubusercontent.com/jacob-baines/vuln_disclosure/main/vuln_2021_03.txt","https://www.youtube.com/watch?v=vdesswZYz-8","http://packetstormsecurity.com/files/163795/Canon-TR150-Driver-3.71.2.10-Privilege-Escalation.html"],"products":["canon:pixma_tr150_firmware"],"source":"nvd","synced_at":"2026-10-19T21:21:57.125947417+00:00"},"epss":{"cve":"CVE-2021-38085","score":0.00981,"percentile":0.62279,"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).
