Summary

CVE-2024-24795 is a medium-severity HTTP Request/Response Splitting (CWE-113) vulnerability in Fedoraproject Fedora. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Content Injection (T1659); ranked in the top 14% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Vulnerability Data

HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue.

Mitigating Controls (NIST 800-53 r5) AI

Input validation stops unneutralized CR/LF characters from being accepted and later emitted in HTTP headers.

Output filtering can neutralize CRLF sequences before they reach HTTP response headers.

Boundary protection at external interfaces can enforce consistent HTTP request/response parsing rules between intermediaries and endpoints.

PR.PS-01 mostly match
prevents

Configuration management can enforce uniform HTTP parsing rules across intermediaries, directly mitigating inconsistent interpretation.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input sanitization and header handling that prevent CRLF injection.

DE.CM-01 partial match
prevents

Network monitoring can detect smuggling attempts via anomalous HTTP traffic or logs, while eliminating the inconsistency directly aids detection of such events.

PR.IR-01 partial match
prevents

Network protections can enforce consistent HTTP proxy/firewall behavior to block smuggling, and removing the weakness helps prevent unauthorized access via request smuggling.

finds

Security testing in development and acceptance can detect CRLF injection flaws before deployment.

degrades

Network security controls can enforce consistent HTTP parsing and proxy behavior that mitigates request smuggling.

degrades

Secure network services include hardening proxies and gateways against inconsistent HTTP interpretation.

prevents

Secure development lifecycle mandates input validation and output encoding that directly prevents CRLF injection into HTTP headers.

prevents

Application security requirements explicitly call for controls against injection flaws including HTTP header manipulation.

prevents

Secure architecture principles reduce the likelihood of header-splitting vulnerabilities through proper component isolation.
