CVE-2023-4957

Credential takeover via unauthenticated CGI settings update

Published Oct 11, 2023 · Updated Aug 28, 2025

Authentication bypass in Zebra Technologies ZT410 203dpi ZPL 18J150703184 allows remote attackers on the same network to change web credentials. The setvarsResults.cgi handler accepts a specially crafted POST request that updates the web-interface username and password without prior authentication. Protected mode must be disabled; successful exploitation modifies management credentials but has no reported availability impact.
