This allows obtaining root permissions within the web management console, because the login process uses Java's ProcessBuilder class and a bash script called antsle-auth with insufficient input validation.","published":"2018-03-07T02:29:04.000Z","lastModified":"2026-06-17T02:03:38.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":["antsle/antman"],"epss":{"score":0.53231,"percentile":0.98976,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.39125,"percentile":0.98571},{"date":"2026-09-22","score":0.53231,"percentile":0.98933}]},"kev":{"listed":false},"exploits":{"count":2,"verified":false,"firstPublished":"2018-03-02","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":44262,"kind":"exploit","title":"antMan 0.9.0c - Authentication Bypass","url":"https://www.exploit-db.com/exploits/44262","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/java/webapps/44262.txt","file":"exploits/java/webapps/44262.txt","published":"2018-03-07","added":"2018-03-07","updated":"2018-03-07","author":"Joshua Bowser","type":"webapps","platform":"java","port":3000,"verified":false,"codes":["CVE-2018-7739"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null},{"edbId":44220,"kind":"exploit","title":"antMan < 0.9.1a - Authentication Bypass","url":"https://www.exploit-db.com/exploits/44220","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/webapps/44220.txt","file":"exploits/multiple/webapps/44220.txt","published":"2018-03-02","added":"2018-03-02","updated":"2018-03-09","author":"Joshua Bowser","type":"webapps","platform":"multiple","port":null,"verified":false,"codes":["CVE-2018-7739"],"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 53.2%, higher than 99% of all known CVEs.
