{"id":"UBUNTU-CVE-2024-43394","details":"Server-Side Request Forgery (SSRF) in Apache HTTP Server on Windows allows to potentially leak NTLM hashes to a malicious server via mod_rewrite or apache expressions that pass unvalidated request input. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.63. Note:  The Apache HTTP Server Project will be setting a higher bar for accepting vulnerability reports regarding SSRF via UNC paths. The server offers limited protection against administrators directing the server to open UNC paths. Windows servers should limit the hosts they will connect over via SMB based on the nature of NTLM authentication.","modified":"2025-07-14T07:16:23.125998Z","published":"2025-07-11T00:00:00Z","withdrawn":"2025-07-15T05:05:38Z","upstream":["CVE-2024-43394"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-43394"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-43394"},{"type":"REPORT","url":"https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2024-43394"},{"type":"REPORT","url":"https://httpd.apache.org/security/vulnerabilities_24.html"}],"affected":[{"package":{"name":"apache2","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.7-1ubuntu4.22+esm9?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.6-2ubuntu2","2.4.6-2ubuntu3","2.4.6-2ubuntu4","2.4.7-1ubuntu1","2.4.7-1ubuntu2","2.4.7-1ubuntu3","2.4.7-1ubuntu4","2.4.7-1ubuntu4.1","2.4.7-1ubuntu4.4","2.4.7-1ubuntu4.5","2.4.7-1ubuntu4.6","2.4.7-1ubuntu4.7","2.4.7-1ubuntu4.8","2.4.7-1ubuntu4.9","2.4.7-1ubuntu4.10","2.4.7-1ubuntu4.11","2.4.7-1ubuntu4.13","2.4.7-1ubuntu4.15","2.4.7-1ubuntu4.16","2.4.7-1ubuntu4.17","2.4.7-1ubuntu4.18","2.4.7-1ubuntu4.19","2.4.7-1ubuntu4.20","2.4.7-1ubuntu4.21","2.4.7-1ubuntu4.22","2.4.7-1ubuntu4.22+esm1","2.4.7-1ubuntu4.22+esm2","2.4.7-1ubuntu4.22+esm3","2.4.7-1ubuntu4.22+esm4","2.4.7-1ubuntu4.22+esm5","2.4.7-1ubuntu4.22+esm6","2.4.7-1ubuntu4.22+esm8","2.4.7-1ubuntu4.22+esm9"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-43394.json"}},{"package":{"name":"apache2","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.18-2ubuntu3.17+esm14?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.12-2ubuntu2","2.4.17-1ubuntu1","2.4.17-2ubuntu1","2.4.17-3ubuntu1","2.4.18-1ubuntu1","2.4.18-2ubuntu1","2.4.18-2ubuntu2","2.4.18-2ubuntu3","2.4.18-2ubuntu3.1","2.4.18-2ubuntu3.2","2.4.18-2ubuntu3.3","2.4.18-2ubuntu3.4","2.4.18-2ubuntu3.5","2.4.18-2ubuntu3.7","2.4.18-2ubuntu3.8","2.4.18-2ubuntu3.9","2.4.18-2ubuntu3.10","2.4.18-2ubuntu3.12","2.4.18-2ubuntu3.13","2.4.18-2ubuntu3.14","2.4.18-2ubuntu3.15","2.4.18-2ubuntu3.17","2.4.18-2ubuntu3.17+esm1","2.4.18-2ubuntu3.17+esm2","2.4.18-2ubuntu3.17+esm3","2.4.18-2ubuntu3.17+esm4","2.4.18-2ubuntu3.17+esm5","2.4.18-2ubuntu3.17+esm6","2.4.18-2ubuntu3.17+esm7","2.4.18-2ubuntu3.17+esm8","2.4.18-2ubuntu3.17+esm9","2.4.18-2ubuntu3.17+esm10","2.4.18-2ubuntu3.17+esm11","2.4.18-2ubuntu3.17+esm12","2.4.18-2ubuntu3.17+esm13","2.4.18-2ubuntu3.17+esm14"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-43394.json"}},{"package":{"name":"apache2","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.29-1ubuntu4.27+esm4?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.27-2ubuntu3","2.4.29-1ubuntu1","2.4.29-1ubuntu2","2.4.29-1ubuntu3","2.4.29-1ubuntu4","2.4.29-1ubuntu4.1","2.4.29-1ubuntu4.2","2.4.29-1ubuntu4.3","2.4.29-1ubuntu4.4","2.4.29-1ubuntu4.5","2.4.29-1ubuntu4.6","2.4.29-1ubuntu4.7","2.4.29-1ubuntu4.8","2.4.29-1ubuntu4.10","2.4.29-1ubuntu4.11","2.4.29-1ubuntu4.12","2.4.29-1ubuntu4.13","2.4.29-1ubuntu4.14","2.4.29-1ubuntu4.16","2.4.29-1ubuntu4.17","2.4.29-1ubuntu4.18","2.4.29-1ubuntu4.19","2.4.29-1ubuntu4.20","2.4.29-1ubuntu4.21","2.4.29-1ubuntu4.22","2.4.29-1ubuntu4.23","2.4.29-1ubuntu4.24","2.4.29-1ubuntu4.25","2.4.29-1ubuntu4.26","2.4.29-1ubuntu4.27","2.4.29-1ubuntu4.27+esm1","2.4.29-1ubuntu4.27+esm2","2.4.29-1ubuntu4.27+esm3","2.4.29-1ubuntu4.27+esm4"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-43394.json"}},{"package":{"name":"apache2","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.41-4ubuntu3.23?arch=source&distro=esm-infra/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.41-1ubuntu1","2.4.41-4ubuntu1","2.4.41-4ubuntu2","2.4.41-4ubuntu3","2.4.41-4ubuntu3.1","2.4.41-4ubuntu3.3","2.4.41-4ubuntu3.4","2.4.41-4ubuntu3.5","2.4.41-4ubuntu3.6","2.4.41-4ubuntu3.7","2.4.41-4ubuntu3.8","2.4.41-4ubuntu3.9","2.4.41-4ubuntu3.10","2.4.41-4ubuntu3.11","2.4.41-4ubuntu3.12","2.4.41-4ubuntu3.13","2.4.41-4ubuntu3.14","2.4.41-4ubuntu3.15","2.4.41-4ubuntu3.16","2.4.41-4ubuntu3.17","2.4.41-4ubuntu3.19","2.4.41-4ubuntu3.20","2.4.41-4ubuntu3.21","2.4.41-4ubuntu3.23"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-43394.json"}},{"package":{"name":"apache2","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.52-1ubuntu4.14?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.48-3.1ubuntu3","2.4.48-3.1ubuntu4","2.4.51-2ubuntu1","2.4.52-1ubuntu1","2.4.52-1ubuntu2","2.4.52-1ubuntu4","2.4.52-1ubuntu4.1","2.
