CVE-2024-34523Public exploitNetwork attack vector

Arbitrary file read via unchecked download path

Published May 7, 2024 · Updated Aug 2, 2024

Path traversal in AChecker 1.5 allows remote attackers to read arbitrary server files through the download.php path parameter. download.php takes the unauthenticated GET path value, checks only whether it contains AC_EXPORT_RPT_DIR, and passes the unnormalized string to readfile(). No account is required; a crafted traversal path can disclose application configuration, source code, or other files readable by the web-server process.
