CVE-2019-4152: IBM Security Access Manager 9.0.1 through 9.0.6 does not invalidate session tokens in a timely manner.

IBM Security Access Manager 9.0.1 through 9.0.6 does not invalidate session tokens in a timely manner. The lack of proper session expiration may allow attackers with local access to login into a closed browser session. IBM X-Force ID: 158515.

Security readout for executives and security teams

Plain-English summary

IBM Security Access Manager versions 9.0.1 through 9.0.6 may leave session tokens valid longer than expected. Someone with local access to a machine could potentially reopen or use a closed browser session. This is mainly a workstation/shared-device risk, not a remote internet exploitation issue based on the provided evidence.

Executive priority

Handle in normal vulnerability remediation cycles, prioritizing environments with shared endpoints or privileged access workflows. This is moderate urgency because impact depends on local access, but identity infrastructure increases business sensitivity.

Technical view

The issue is improper session expiration in IBM Security Access Manager 9.0.1-9.0.6. CVSS 3.0 score is 5.1, with local attack vector, low complexity, no privileges, no user interaction, and low confidentiality and integrity impact. IBM X-Force tracks it as 158515.

Likely exposure

Organizations running IBM Security Access Manager 9.0.1 through 9.0.6 are in scope. Exposure is highest where users access protected sessions from shared workstations, kiosks, jump boxes, or unmanaged endpoints.

Exploitation context

The source bundle does not indicate CISA KEV listing or active exploitation. The described attacker needs local access to the device where a browser session was closed but tokens were not promptly invalidated.

Researcher notes

Evidence is limited to CVE, IBM advisory, and IBM X-Force references in the bundle. No CWE is provided. Do not assume remote exploitability, affected versions beyond 9.0.1-9.0.6, or a specific fixed version without consulting IBM guidance.

Mitigation direction

  • Inventory IBM Security Access Manager and identify versions 9.0.1 through 9.0.6.
  • Review IBM advisory and X-Force entry for the official remediation path.
  • Apply IBM-recommended fixes or upgrades through normal change control.
  • Reduce shared-browser use until remediation is confirmed.
  • Require users to sign out and lock workstations after sensitive sessions.

Validation and detection

  • Confirm no production instance remains on IBM Security Access Manager 9.0.1 through 9.0.6.
  • Verify IBM-recommended remediation is applied and documented.
  • Validate session tokens expire promptly after logout or browser closure.
  • Review access logs for suspicious reuse from shared or local endpoints.
