CVE-2015-4684 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 6.5.
A proof-of-concept (PoC) exploit exists for CVE-2015-4684. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
