DescriptionCVE.org

SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker.  Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request.

Users are recommended to upgrade to version 2.4.64 which fixes this issue.

AnalysisAI

CVE-2024-43204 is a Server-Side Request Forgery (SSRF) vulnerability in Apache HTTP Server when mod_proxy is loaded, allowing unauthenticated attackers to initiate outbound proxy requests to attacker-controlled URLs. The vulnerability requires an uncommon configuration where mod_headers is used to modify Content-Type headers based on user-supplied HTTP request values. Apache recommends immediate upgrade to version 2.4.64 to remediate this high-integrity-impact issue.

Technical ContextAI

The vulnerability exists in Apache HTTP Server's mod_proxy module (CWE-918: Server-Side Request Forgery) and is triggered through unsafe interaction with mod_headers when processing request/response headers. When mod_headers is configured to dynamically modify the Content-Type header using values derived from incoming HTTP requests (e.g., via user input, request parameters, or header reflection), an attacker can inject crafted values that cause mod_proxy to interpret the request as a legitimate proxy request to an arbitrary destination. This exploits improper validation of proxy request destinations, allowing the attacker to use the vulnerable server as an intermediary to reach internal or external systems that would otherwise be inaccessible. The root cause is insufficient sanitization of header values before they are processed by the proxy logic. Affected CPE: cpe:2.3:a:apache:http_server:*:*:*:*:*:*:*:* (versions prior to 2.4.64).

RemediationAI

Upgrade Apache HTTP Server to version 2.4.64 or later; priority: High; link: https://httpd.apache.org/download.cgi Workaround (Temporary): Disable mod_proxy if not required for operations; priority: High Workaround (Temporary): Review and restrict mod_headers configuration: avoid using Header directives that incorporate unsanitized user input (request parameters, cookies, client-supplied headers) into Content-Type or other proxy-relevant headers; priority: High Mitigation: Implement network-level egress filtering or proxy whitelisting to restrict outbound connections from the HTTP Server to authorized destinations only; priority: Medium Detection: Monitor Apache access logs for unusual outbound proxy requests (via mod_proxy logging) and anomalous Content-Type header values in requests; priority: Medium
