Technical Analysis
IBM DataPower Gateway versions 10.5.0.0 to 10.5.0.22, 10.6.0.0 to 10.6.0.10, 10.6.1 to 10.6.6, and 11.0.0.0 to 11.0.0.2 contain a vulnerability (CWE-347) where improper verification of cryptographic signatures enables remote attackers to bypass authentication by forging valid JSON Web Signatures. This flaw compromises the integrity of authentication mechanisms relying on these signatures.
Potential Impact
Successful exploitation of this vulnerability allows remote attackers to bypass authentication controls, potentially gaining unauthorized access with high confidentiality and integrity impact. Availability is not affected. This could lead to unauthorized access to sensitive data or system functions within affected IBM DataPower Gateway instances.
Mitigation Recommendations
No explicit patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is applied, organizations should consider additional compensating controls to monitor and restrict access to affected systems.
