Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-23 Session Authenticity good match

prevent

SC-23 requires mechanisms to protect session authenticity including resistance to fixation attacks, directly addressing the Drupal TFA session fixation vulnerability.

SI-2 Flaw Remediation good match

prevent

SI-2 mandates timely identification, reporting, and correction of system flaws, enabling patching of the vulnerable TFA module per Drupal SA-CONTRIB-2024-043.

AC-12 Session Termination partial match

prevent

AC-12 enforces session termination after inactivity or trigger events, limiting the exploitation window for fixed sessions.

Why these techniques?

Session fixation vulnerability in Drupal TFA module enables exploitation of a public-facing web application to bypass access controls via improper session migration during multi-factor authentication.

NVD Description

Session Fixation vulnerability in Drupal Two-factor Authentication (TFA) allows Session Fixation.This issue affects Two-factor Authentication (TFA): from 0.0.0 before 1.8.0.

Deeper analysisAI

CVE-2024-13279 is a session fixation vulnerability in the Drupal Two-factor Authentication (TFA) module. This issue affects all versions of the TFA module from 0.0.0 before 1.8.0 and is classified under CWE-384 (Session Fixation).

The vulnerability has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable remotely over the network by unauthenticated attackers with low attack complexity and no user interaction required. Successful exploitation allows attackers to fix a session ID, potentially hijacking authenticated sessions and achieving high impacts on confidentiality, integrity, and availability.
