CVE-2022-24891 Information

Description

ESAPI (The OWASP Enterprise Security API) is a free open source web application security control library. Prior to version 2.3.0.0 there is a potential for a cross-site scripting vulnerability in ESAPI caused by a incorrect regular expression for \onsiteURL\ in the antisamy-esapi.xml configuration file that can cause \javascript:\ URLs to fail to be correctly sanitized. This issue is patched in ESAPI 2.3.0.0. As a workaround manually edit the antisamy-esapi.xml configuration files to change the \onsiteURL\ regular expression. More information about remediation of the vulnerability including the workaround is available in the maintainers’ release notes and security bulletin.
