CVE-2021-41615: Critical severity embedthis goahead web server vulnerability

Published Aug 8, 2022
·
Updated

websda.c in GoAhead WebServer 2.1.8 has insufficient nonce entropy because the nonce calculation relies on the hardcoded onceuponatimeinparadise value, which does not follow the secret-data guideline for HTTP Digest Access Authentication in RFC 7616 section 3.3 (or RFC 2617 section 3.2.1). NOTE: 2.1.8 is a version from 2003; however, the affected websda.c code appears in multiple derivative works that may be used in 2021. Recent GoAhead software is unaffected.
