Technical details
IBM watsonx.data intelligence versions 5.2.2 through 5.3.1 patch-1 are vulnerable to cleartext transmission of sensitive information (CWE-319). The vulnerability stems from a failure to enforce encrypted communication channels for certain data transfers. A remote attacker with the ability to intercept network traffic (Man-in-the-Middle) can capture sensitive data as it passes between the application and other endpoints. Exploitation requires the attacker to be positioned on the network path but does not require prior authentication. IBM has addressed this issue in Watson Data Intelligence version 5.3.1-patch3.
Affected products
- IBM watsonx.data intelligence 5.2.2, 5.3.0, 5.3.1, 5.3.1 through patch-1
