IBM Security Identity Governance and Intelligence 5.2.6 could allow a remote attacker to obtain sensitive information, caused by the failure to set the secure flag for the session cookie in SSL mode. By intercepting its transmission within an HTTP session, an attacker could exploit this vulnerability to capture the cookie and obtain sensitive information. IBM X-Force ID: 175360.

Security readout for executives and security teams

Plain-English summary

IBM Security Identity Governance and Intelligence 5.2.6 may expose session cookies because the Secure flag is not set correctly in SSL mode. If a user’s session cookie is transmitted over HTTP and an attacker can observe that traffic, the attacker may obtain sensitive information.

Executive priority

Treat as a targeted, low-severity confidentiality issue. It should be fixed during normal vulnerability remediation cycles, sooner for internet-facing identity governance systems or environments with mixed HTTP and HTTPS access paths.

Technical view

The issue is improper session cookie handling: the Secure attribute is absent in SSL mode. CVSS 3.0 is 3.7 with network attack vector, no privileges or user interaction, high attack complexity, and low confidentiality impact only. Integrity and availability are not affected in the provided sources.

Likely exposure

Exposure is limited to IBM Security Identity Governance and Intelligence 5.2.6 deployments. Risk is higher where users can reach the application over untrusted networks, mixed HTTP/HTTPS paths exist, or session cookies can traverse non-HTTPS connections.

Exploitation context

The bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation depends on a remote attacker being able to intercept relevant HTTP session traffic, which aligns with the high attack complexity in the CVSS vector.

Researcher notes

Primary evidence identifies only IBM Security Identity Governance and Intelligence 5.2.6. The provided bundle does not include CWE mapping or detailed fix version. Avoid broad product assumptions and verify remediation directly against IBM’s advisory and local cookie behavior.

Mitigation direction

  • Review IBM advisory and apply the vendor-supported remediation for version 5.2.6.
  • Confirm all application access is HTTPS-only, with HTTP redirected or blocked.
  • Validate session cookies include the Secure attribute after remediation.
  • Restrict access to trusted networks until vendor remediation is complete.
  • Monitor for unusual session reuse or account access anomalies.

Validation and detection

  • Inventory IBM Security Identity Governance and Intelligence instances and confirm any version 5.2.6 deployments.
  • Inspect application Set-Cookie headers over HTTPS for the Secure attribute.
  • Check whether any HTTP endpoint can receive or transmit session cookies.
  • Review edge proxy and TLS termination behavior for cookie handling changes.
  • Record remediation status against the IBM advisory and CVE ID.
