CVE-2020-14977

CVE-2020-14977 describes a high-severity vulnerability in F-Secure SAFE 17.7 on macOS, where XPC services improperly use Process IDs (PIDs) for client identification. This flaw allows an attacker to perform a PID reuse attack, enabling them to connect to privileged XPC services and execute arbitrary commands with elevated privileges on an already compromised system. The attack has high impact on confidentiality, integrity, and availability, but requires high attack complexity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
