CVE-2019-4153: IBM Security Access Manager 9.0.1 through 9.0.6 could allow a remote attacker to conduct phishing attacks,...

IBM Security Access Manager 9.0.1 through 9.0.6 could allow a remote attacker to conduct phishing attacks, using an open redirect attack. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to spoof the URL displayed to redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain highly sensitive information or conduct further attacks against the victim. IBM X-Force ID: 158517.

Security readout for executives and security teams

Plain-English summary

This flaw lets an attacker abuse IBM Security Access Manager as a trusted-looking redirector in phishing. A victim must be persuaded to visit a crafted site, but the trusted IBM Access Manager URL can make credential theft or follow-on attacks more convincing.

Executive priority

Treat this as a moderate identity and phishing risk, not a direct system takeover. Remediate affected IBM Access Manager deployments because trusted authentication infrastructure can materially increase phishing success and downstream business impact.

Technical view

CVE-2019-4153 is an open redirect vulnerability in IBM Security Access Manager 9.0.1 through 9.0.6. The CVSS 3.0 score is 6.8. The vector indicates network access, low complexity, required user interaction, low attacker privileges, changed scope, and high integrity impact.

Likely exposure

Exposure is limited to organizations running IBM Security Access Manager versions 9.0.1, 9.0.2, 9.0.3, 9.0.4, 9.0.5, or 9.0.6, especially where user-facing login or access-management URLs are reachable by employees, customers, or partners.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The realistic risk is phishing: attackers can make malicious destinations appear associated with a trusted Access Manager URL if a user follows the lure.

Researcher notes

Evidence identifies an open redirect with user interaction required and low attacker privilege per CVSS. The bundle does not provide endpoint details, exploit proof, or exact fixed versions, so validation should stay inventory- and advisory-driven.

Mitigation direction

  • Inventory IBM Security Access Manager versions in production and externally reachable environments.
  • Review IBM advisory ibm10888379 for the official fix or upgrade path.
  • Prioritize remediation for internet-facing or identity-critical deployments.
  • Monitor access logs for unusual redirect patterns tied to authentication flows.
  • Reinforce phishing controls for messages abusing trusted Access Manager URLs.

Validation and detection

  • Confirm no deployment runs IBM Security Access Manager 9.0.1 through 9.0.6.
  • Check whether affected Access Manager URLs are externally reachable.
  • Review IBM X-Force ID 158517 against internal vulnerability records.
  • Validate remediation status in asset inventory and patch records.
  • Search security telemetry for suspicious redirects from Access Manager hosts.
