Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2008-5284. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
