CVE-2020-4207
IBM Watson IoT Message Gateway 2.0.0.x, 5.0.0.0, 5.0.0.1, and 5.0.0.2 is vulnerable to a buffer overflow, caused by improper bounds checking when handling a failed HTTP request with specific content in the headers.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
