Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-13279 is a critical-severity Session Fixation (CWE-384) vulnerability in Two-Factor Authentication Project Two-Factor Authentication. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 38th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-23 (Session Authenticity) and AC-12 (Session Termination) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.
The Drupal security advisory SA-CONTRIB-2024-043 at https://www.drupal.org/sa-contrib-2024-043 provides details on mitigation, including available patches.

Mitigating Controls (NIST 800-53 r5) AI
Requires protection of session authenticity, which directly stops an attacker from using a stolen or fixed session identifier after authentication.
Limits the lifetime of any session (fixed or not), thereby reducing the window during which a stolen identifier remains usable.
Enforces that only properly authorized (i.e., freshly authenticated) sessions can access resources, making a pre-existing fixed session ID unusable.
Forces re-authentication under defined conditions, which should result in issuance of a fresh session identifier and invalidation of any prior one.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Managing identities and credentials includes handling session identifiers as temporary credentials that must be invalidated on re-authentication.
Proper authentication processes must invalidate prior session identifiers to prevent fixation attacks.
Protecting and verifying identity assertions encompasses secure handling and regeneration of session tokens.
Configuration baselines can enforce session regeneration and timeout settings that block fixation.
