{"id":"CVE-2018-16946","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-16946","generatedAt":"2026-10-28T20:26:11.025Z","title":"Attackers are able to download /updownload/t.report (aka Log & Report) files and download backup files (via download.php) without authenticating.","description":"LG LNB*, LND*, LNU*, and LNV* smart network camera devices have broken access control. Attackers are able to download /updownload/t.report (aka Log & Report) files and download backup files (via download.php) without authenticating. These backup files contain user credentials and configuration information for the camera device. An attacker is able to discover the backup filename via reading the system logs or report data, or just by brute-forcing the backup filename pattern. It may be possible to authenticate to the admin account with the admin password.","published":"2018-09-12T01:29:00.000Z","lastModified":"2026-06-17T01:45:02.000Z","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-552"],"affected":["lg/lnb5110 firmware","lg/lnb5320 firmware","lg/lnb5320r firmware","lg/lnb7210 firmware","lg/lnd3230r firmware","lg/lnd5110 firmware","lg/lnd5110r firmware","lg/lnd5220r firmware","lg/lnd7210 firmware","lg/lnd7210r firmware","lg/lnu3230r firmware","lg/lnu5110r firmware","lg/lnu5320r firmware","lg/lnu7210r firmware","lg/lnv5110r firmware","lg/lnv5320r firmware","lg/lnv7210 firmware","lg/lnv7210r firmware"],"epss":{"score":0.09348,"percentile":0.95362,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.06833,"percentile":0.93808},{"date":"2026-09-22","score":0.09348,"percentile":0.95159}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2018-09-12","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":45394,"kind":"exploit","title":"LG Smart IP Camera 1508190 - Backup File Download","url":"https://www.exploit-db.com/exploits/45394","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/webapps/45394.py","file":"exploits/hardware/webapps/45394.py","published":"2018-09-12","added":"2018-09-12","updated":"2018-09-12","author":"Ege Balci","type":"webapps","platform":"hardware","port":null,"verified":false,"codes":["CVE-2018-16946"],"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 9.3%.
