{"id":"CVE-2018-7669","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-7669","generatedAt":"2026-10-29T03:02:10.018Z","title":"The 'Log Viewer' application is vulnerable to a directory traversal attack, allowing an attacker to access arbitrary files from the host Operating System using a sitecore/shell/default.aspx?xmlcontrol=LogViewerDetails&file= URI.","description":"An issue was discovered in Sitecore Sitecore.NET 8.1 rev. 151207 Hotfix 141178-1 and above. The 'Log Viewer' application is vulnerable to a directory traversal attack, allowing an attacker to access arbitrary files from the host Operating System using a sitecore/shell/default.aspx?xmlcontrol=LogViewerDetails&file= URI. Validation is performed to ensure that the text passed to the 'file' parameter correlates to the correct log file directory. This filter can be bypassed by including a valid log filename and then appending a traditional 'dot dot' style attack.","published":"2018-04-27T16:29:01.000Z","lastModified":"2026-06-17T02:03:31.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-22"],"affected":["sitecore/sitecore.net"],"epss":{"score":0.16921,"percentile":0.97042,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.1099,"percentile":0.95761},{"date":"2026-09-22","score":0.17227,"percentile":0.9696}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2018-08-06","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":45152,"kind":"exploit","title":"Sitecore.Net 8.1 - Directory Traversal","url":"https://www.exploit-db.com/exploits/45152","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/aspx/webapps/45152.txt","file":"exploits/aspx/webapps/45152.txt","published":"2018-08-06","added":"2018-08-06","updated":"2018-08-09","author":"Chris","type":"webapps","platform":"aspx","port":null,"verified":false,"codes":["CVE-2018-7669"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 16.9%, higher than 97% of all known CVEs.
