{"id":"CVE-2026-11958","state":"PUBLISHED","title":"Local privilege escalation in ANSSI’s DFIR-ORC","description":"Local privilege escalation by loading DLLs from a shared temporary directory in ANSSI’s DFIR-ORC, versions 10.2.7 and prior. An attacker with prior access to the system, can place a malicious DLL in C:\\Windows\\Temp and wait for the application to be executed. Because DFIR-ORC is extracted and executed from that location with administrative privileges, the malicious library can be loaded automatically, allowing the attacker to gain administrator privileges on the affected machine.","publishedAt":"2026-06-18T11:01:16.727Z","updatedAt":"2026-06-18T12:28:09.762Z","severity":{"score":7.3,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","source":"INCIBE"},"assigner":"INCIBE","products":["ANSSI DFIR-ORC"],"affected":[{"vendor":"ANSSI","product":"DFIR-ORC","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"10.2.7","versionType":"custom"},{"version":"10.3.0","status":"unaffected"}]}],"references":["https://www.incibe.es/en/incibe-cert/notices/aviso/local-privilege-escalation-anssis-dfir-orc","https://github.com/DFIR-ORC/dfir-orc/releases/tag/v10.3.0"],"weaknesses":["CWE-427"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/11xxx/CVE-2026-11958.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-11958","state":"PUBLISHED","datePublished":"2026-06-18T11:01:16.727Z","dateUpdated":"2026-06-18T12:28:09.762Z","assignerShortName":"INCIBE","assignerOrgId":"0cbda920-cd7f-484a-8e76-bf7f4b7f4516","dateReserved":"2026-06-11T07:32:37.322Z"},"containers":{"cna":{"title":"Local privilege escalation in ANSSI’s DFIR-ORC","descriptions":[{"lang":"en","value":"Local privilege escalation by loading DLLs from a shared temporary directory in ANSSI’s DFIR-ORC, versions 10.2.7 and prior.
