DescriptionCVE.org

IBM webMethods API Gateway (on-prem) 10.11 through 10.11_Fix3210.15 to 10.15_Fix2711.1 to 11.1_Fix7 IBM webMethods API Management (on-prem) fails to properly validate user-supplied input passed to the url parameter on the /createapi endpoint. An attacker can modify this parameter to use a file:// URI schema instead of the expected https:// schema, enabling unauthorized arbitrary file read access on the underlying server file system.

AnalysisAI

Improper input validation in IBM webMethods API Gateway and API Management allows authenticated attackers to read arbitrary files on the server by supplying a file:// URI to the /createapi endpoint instead of the expected https:// schema. Affected versions include webMethods API Gateway 10.11 through 11.1_Fix7 and webMethods API Management on-premises installations. No patch is currently available for this medium-severity vulnerability.
