Technical details
IBM watsonx.data intelligence is vulnerable to a denial of service (DoS) attack due to improper allocation of resource throttling (CWE-770). An authenticated attacker with network access can send a specially crafted HTTP request that consumes excessive system resources. This occurs because the application fails to properly limit or throttle specific resource-intensive requests. Successful exploitation allows the attacker to cause a temporary denial of service for legitimate users. The issue is addressed in version 5.3.1.
Affected products
- IBM watsonx.data intelligence 5.2.0, 5.2.1, 5.2.2, 5.3.0
