Missing validation of header name and value in codeigniter4/framework

Moderate severity GitHub Reviewed Published Jan 18, 2025 in codeigniter4/CodeIgniter4 • Updated Jan 21, 2025

Package

composer codeigniter4/framework (Composer)

Affected versions

< 4.5.8

Patched versions

4.5.8

Description

Impact

Lack of proper header validation for its name and value. The potential attacker can construct deliberately malformed headers with Header class. This could disrupt application functionality, potentially causing errors or generating invalid HTTP requests. In some cases, these malformed requests might lead to a DoS scenario if a remote service’s web application firewall interprets them as malicious and blocks further communication with the application.

Patches

Upgrade to v4.5.8 or later.

Workarounds

Validate HTTP header keys and/or values if using user-supplied values before passing them to Header class.

Differences from CVE-2023-29197

  1. Affected Software:

    • CVE-2023-29197 specifically addresses a vulnerability in the guzzlehttp/psr7 library.
    • The reported issue in this Security Advisory is within the CodeIgniter4 framework and does not depend on or use the guzzlehttp/psr7 library.

  2. Root Cause and Implementation:

    • The vulnerability reported arises from an issue in the Header class of CodeIgniter4, which is unrelated to the functionality or implementation of guzzlehttp/psr7.

  3. Scope of Impact:

    • The vulnerability described in this Security Advisory affects applications built with the CodeIgniter4 framework, which does not use or rely on the guzzlehttp/psr7 library.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
