Can you explain this vulnerability to me?
This vulnerability involves the allocation of resources without any limits or throttling in File Station 5. If a remote attacker obtains an administrator account, they can exploit this flaw to consume resources excessively, preventing other systems, applications, or processes from accessing the same type of resource.
How can this vulnerability impact me? :
The impact of this vulnerability is that an attacker with administrator access can cause denial of service by exhausting resources. This prevents other legitimate systems, applications, or processes from accessing necessary resources, potentially disrupting normal operations.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
