Certificate Signed Using Weak Hashing Algorithm impact on a workstation

I did a vulnerability scan on some of our company workstations. These are workstations used by employees (dev, HR, accounting, etc.) to do their job. One of the common result I found is SSL/TLS Certificate Signed Using Weak Hashing Algorithm. Based on the vulnerability description "An attacker can exploit this to generate another certificate with the same digital signature, allowing an attacker to masquerade as the affected service." I’m thinking this is more on a server side.

My question is, what could be the impact of this in an ordinary workstation?
What can an attacker/pentester do to the workstation with this vulnerability?
