NixOS vulnerability analysis and mitigation
Overview
Caddy v2.4 contains an open redirect vulnerability identified as CVE-2022-29718. This vulnerability allows remote unauthenticated attackers to redirect users to arbitrary web URLs by tricking victims into clicking on crafted links (CVE Mitre).
Technical details
The vulnerability stems from improper path sanitization in the MatchPath functionality. The issue occurred because the TrimRight operation to remove trailing dots was performed before cleaning the path, which prevented double-dots at the end of the path from being properly sanitized (GitHub PR).
Impact
When successfully exploited, this vulnerability enables attackers to redirect users to arbitrary websites, potentially leading to phishing attacks or other malicious redirections (FortiGuard).
Mitigation and workarounds
The vulnerability has been fixed in Caddy v2.5.0. Users are recommended to upgrade to version 2.5.0 or later to mitigate this security issue. For Fedora users, a security update (caddy-2.4.6-6.fc36) has been released that includes the backported fix (Fedora Update).
