Note: It is argued that OpenCMS allows only registered users to upload different kind of content artifacts (SVG, .doc, .docx). The uploaded content is stored in the CMS content repository \"as is\". In case of scripts inside an SVG, this may or may not be \"malicious\", there is no way of knowing if the uploaded SVG contains the script for a reason. To exploit the \"issue\", a user must have an account in the CMS as a content manager","published":"2018-03-20T07:29:00.000Z","lastModified":"2026-06-17T02:05:26.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":8.8,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-352"],"affected":["alkacon/opencms"],"epss":{"score":0.02108,"percentile":0.81673,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2018-04-02","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":44391,"kind":"exploit","title":"OpenCMS 10.5.3 - Cross-Site Request Forgery","url":"https://www.exploit-db.com/exploits/44391","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/php/webapps/44391.html","file":"exploits/php/webapps/44391.html","published":"2018-04-02","added":"2018-04-02","updated":"2018-04-02","author":"Sureshbabu Narvaneni","type":"webapps","platform":"php","port":null,"verified":false,"codes":["CVE-2018-8811"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB and the impact is high, while EPSS rates exploitation at 2.1%.
