Triggering this can fetch the username and passwords of the helpdesk employees in the URI. This leads to a privilege escalation, from unauthenticated to user-level access, leading to full account takeover. The attack fetches multiple credentials because they are stored in the database (stored XSS). This affects the mobile/chat URI via the lgn and psswrd parameters.","severity":{"version":"3.1","score":9.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","level":"critical","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-10","score":0.02485,"percentile":0.84747,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":false},"cwes":["CWE-79"],"published":"2020-03-09T18:27:20Z","modified":"2026-06-17T03:28:31Z","exploits":[{"source":"pocgithub","id":"ari034/CVE-2020-9758","title":"ari034/CVE-2020-9758","date":"2020-03-07","url":"https://github.com/ari034/CVE-2020-9758"}],"products":[{"vendor":"livezilla","product":"livezilla"}],"references":[{"url":"https://github.com/ari034/CVE-2020-9758","tags":["x_refsource_MISC","x_transferred","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-9758"},{"url":"https://github.com/advisories/GHSA-m978-hcqw-jcmw"}],"sources":{"cve":[{"id":"CVE-2020-9758","description":"An issue was discovered in chat.php in LiveZilla Live Chat 8.0.1.3 (Helpdesk).
