AI-suggested

1. Immediately upgrade TecharoHQ Anubis to version 1.21.3 or later, where the vulnerability is fully patched. 2. Implement strict input validation and sanitization on the ?redir= parameter to accept only safe URL schemes (http, https) or local paths, blocking all others. 3. Configure web application firewalls (WAFs) or reverse proxies to detect and block requests to the /.within.website/x/cmd/anubis/api/pass-challenge endpoint with suspicious or malformed ?redir= parameters. 4. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of potential XSS attacks. 5. Conduct user awareness training to recognize suspicious URLs and avoid clicking on untrusted links. 6. Monitor logs for unusual access patterns or repeated requests to the vulnerable endpoint that could indicate exploitation attempts. 7. If upgrading immediately is not feasible, apply the recommended workaround by blocking requests with unsafe ?redir= parameter values at the network or application level.

Description

Anubis is a Web AI Firewall Utility that weighs the soul of users' connections using one or more challenges in order to protect upstream resources from scraper bots. In versions 1.21.2 and below, attackers can craft malicious pass-challenge pages that cause a user to execute arbitrary JavaScript code or trigger other nonstandard schemes. An incomplete version of this fix was tagged at 1.21.2 and then the release process was aborted upon final testing. To work around this issue: block any requests to the /.within.website/x/cmd/anubis/api/pass-challenge route with the ?redir= parameter set to anything that doesn't start with the URL scheme http, https, or no scheme (local path redirect). This was fixed in version 1.21.3.
