Apache Allura v1.0.1-1.16.0 DNS Rebinding Vulnerability in Import Component
CVE-2024-36471 Published on June 10, 2024
Import functionality is vulnerable to DNS rebinding attacks between verification and processing of the URL. Project administrators can run these imports, which could cause Allura to read from internal services and expose them. This issue affects Apache Allura from 1.0.1 through 1.16.0. Users are recommended to upgrade to version 1.17.0, which fixes the issue. If you are unable to upgrade, set "disable_entry_points.allura.importers = forge-tracker, forge-discussion" in your .ini config file.

CVE-2024-36471 has been classified to as an Information Disclosure vulnerability or weakness.
What is a SSRF Vulnerability?
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
CVE-2024-36471 has been classified to as a SSRF vulnerability or weakness.
