While exploitation was not seen prior to disclosure, it is likely that these vulnerabilities will start to be exploited by attackers who modify the Proof-of-Concept exploit for their own use. This article demonstrates the need to stay up to date on patching, as the patch was released nearly 3 months before these exploits were made public. Additionally, these vulnerabilities demonstrate the need for a defense-in-depth strategy, as many of these cannot be exploited without requiring other this such as valid credentials or local access – this allows for detection opportunities at different parts of the attack chain.
