Summary

CVE-2024-7341 is a high-severity Session Fixation (CWE-384) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Steal Web Session Cookie (T1539); ranked in the top 47% of CVEs by exploit likelihood; 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.

Vulnerability Data

A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the…

Mitigating Controls (NIST 800-53 r5) AI

SC-23 Session Authenticity good match

Requires protection of session authenticity, which directly stops an attacker from using a stolen or fixed session identifier after authentication.

AC-12 Session Termination partial match

Limits the lifetime of any session (fixed or not), thereby reducing the window during which a stolen identifier remains usable.

AC-3 Access Enforcement partial match

Enforces that only properly authorized (i.e., freshly authenticated) sessions can access resources, making a pre-existing fixed session ID unusable.

IA-11 Re-authentication partial match

Forces re-authentication under defined conditions, which should result in issuance of a fresh session identifier and invalidation of any prior one.

Mitigating Controls (NIST CSF 2.0) AI

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.

PR.AA-03 mostly match
prevents

Proper authentication processes must invalidate prior session identifiers to prevent fixation attacks.

PR.AA-01 partial match
prevents

Managing identities and credentials includes handling session identifiers as temporary credentials that must be invalidated on re-authentication.

PR.AA-04 partial match
prevents

Protecting and verifying identity assertions encompasses secure handling and regeneration of session tokens.

PR.PS-01 partial match
prevents

Configuration baselines can enforce session regeneration and timeout settings that block fixation.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect session-fixation issues, yet the weakness absence does not replace comprehensive testing.

A.5.15 Access control partial match
degrades

Access-control policy can mandate session invalidation on re-authentication, but does not prescribe the technical mechanism.

A.5.16 Identity management partial match
degrades

Identity-management procedures can require new session tokens after login, yet the control is broader than session handling.

A.5.17 Authentication information partial match
degrades

Authentication-information rules can include session-token lifecycle requirements, but the control focuses on credential management.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC requirement can embed session-fixation checks, but eliminating the weakness does not satisfy the full SDLC control.

A.8.26 Application security requirements partial match
prevents

Application-security requirements can specify session handling, yet the weakness fix alone does not meet the broader requirement.
