27
FAUCET Score

CVE-2017-13905 is a race condition vulnerability affecting Apple's iOS, macOS, tvOS, and watchOS that could allow an application to gain elevated privileges. With a CVSS score of 8.1 (HIGH), it presents a significant risk due to its network-based attack vector and high impact on confidentiality, integrity, and availability, despite a high attack complexity. While no public exploits or Metasploit modules are available, and there's minimal community discussion, the potential for privilege escalation makes patching critical.
