Loading vulnerability…
CVE-2026-24072 is an improper privilege-management vulnerability in Apache HTTP Server mod_rewrite affecting version 2.4.66 and earlier. A local user able to author a .htaccess file can manipulate it to read files using the privileges of the httpd process.

Repository is a real proof-of-concept and validation lab for CVE-2026-24072, an Apache HTTP Server local privilege-escalation / information-disclosure issue affecting .htaccess expression handling in 2.4.66 and earlier. It is not an exploit framework module; instead it combines vulnerability analysis, patch diffs, example malicious .htaccess payloads, and a Dockerized test harness that can swap between vulnerable and fixed mod_rewrite builds. Core exploit capability: attacker-controlled .htaccess files use RewriteCond expr with restricted ap_expr primitives (file(), filesize(), -f, -d, -e, -s, -L, -x) to access filesystem information outside normal .htaccess confinement. In vulnerable builds, these expressions are parsed without AP_EXPR_FLAG_RESTRICTED, allowing local users who can write .htaccess files to read arbitrary files or probe filesystem state with httpd's privileges. The strongest included case is tests/htdocs/test/c6/.htaccess, which reads /opt/sentinel/secret.txt and matches SENTINEL_TOKEN to prove content disclosure. Other cases demonstrate existence, directory, non-empty, executable, and symlink probes. Repository structure: documentation files (README.md, CVE-2026-24072-analysis.md, docs/TESTING.md, docs/session/*) explain the bug, patch, and lab design; diff files (mod_rewrite.diff, mod_setenvif.diff, mod_proxy_fcgi.diff) show the fix; examples/ contains exploit.htaccess and safe-expressions.htaccess; docker/Dockerfile builds Apache 2.4.67 plus two swappable mod_rewrite DSOs; scripts/ contains lifecycle, swap, and automated test scripts; tests/conf/httpd.conf and tests/htdocs/test/* provide the vulnerable/fixed validation fixtures; tests/matrix.tsv defines expected outcomes. Operationally, the Docker lab builds Apache 2.4.67, compiles mod_rewrite_fixed.so from 2.4.67 source and mod_rewrite_vuln.so from 2.4.66 source, and swaps the active module via symlink /opt/httpd/modules/mod_rewrite.so. The service listens on port 8080. Automated tests curl /test/c1..c9 and /test/n1..n3, expecting vulnerable builds to return 200 with rewrite-fired indicators and fixed builds to return 500 with 'restricted' errors for restricted expressions while allowing negative-control expressions. The repository also documents related affected modules mod_setenvif and mod_proxy_fcgi via patch diffs, but the runnable lab focuses on mod_rewrite only.
