Two critical vulnerabilities, CVE-2025-27364 in MITRE Caldera and CVE-2024-34331 in Parallels Desktop, pose significant security risks. CVE-2025-27364 allows Remote Code Execution on Caldera servers, while CVE-2024-34331 enables Local Privilege Escalation on macOS systems. Until patches are available, organizations should update Caldera to the latest version, implement network segmentation, and monitor for unusual activity, while removing SUID permissions from Parallels tools and segmenting network access for Parallels Desktop.
