{"id":"CVE-2025-7073","state":"PUBLISHED","title":"Local Privilege Escalation via Arbitrary File Operation in Bitdefender Total Security","description":"A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\\ProgramData\\Atc\\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.","publishedAt":"2025-12-10T09:46:40.263Z","updatedAt":"2026-03-31T11:43:59.146Z","severity":{"score":8.8,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","source":"Bitdefender"},"assigner":"Bitdefender","products":["Bitdefender Total Security","Bitdefender Internet Security","Bitdefender Antivirus Plus"],"affected":[{"vendor":"Bitdefender","product":"Total Security","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"27.0.47.241","versionType":"custom"}],"platforms":["Windows"]},{"vendor":"Bitdefender","product":"Internet Security","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"27.0.47.241","versionType":"custom"}],"platforms":["Windows"]},{"vendor":"Bitdefender","product":"Antivirus Plus","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"27.0.47.241","versionType":"custom"}]}],"references":["https://www.bitdefender.com/support/security-advisories/local-privilege-escalation-via-arbitrary-file-operation-in-bitdefender-atc-va-12590"],"weaknesses":["CWE-59"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/7xxx/CVE-2025-7073.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-7073","state":"PUBLISHED","datePublished":"2025-12-10T09:46:40.263Z","dateUpdated":"2026-03-31T11:43:59.146Z","assignerShortName":"Bitdefender","assignerOrgId":"b3d5ebe7-963e-41fb-98e1-2edaeabb8f82","dateReserved":"2025-07-04T15:58:42.058Z"},"containers":{"cna":{"title":"Local Privilege Escalation via Arbitrary File Operation in Bitdefender Total Security","descriptions":[{"lang":"en","value":"A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges.
