Repository contains a local macOS privilege-escalation exploit for CVE-2024-11467 targeting VMware Horizon Client’s privileged helper tool (CDSHelper). Structure: - README.md: Technical write-up describing the XPC Mach service (com.vmware.horizon.CDSHelper), reverse engineering notes, and the vulnerable job handler that supports operations like runscript/movefile/installpackage. It explains the core abuse: using the helper’s file-move job to relocate a root-owned, partially attacker-influenced file into /etc/sudoers.d/. - poc.c: C PoC that creates an XPC dictionary with keys `cdsjob=cdsjob_movefile`, `cds_movefile_srcfile=/var/log/install.log`, and `cds_movefile_dstdir=/etc/sudoers.d/myfile`, then connects to the Mach service `com.vmware.horizon.CDSHelper` and sends the message with a reply handler. - exploit.sh: Orchestrator script that (1) injects a sudoers line into /var/log/install.log using `logger` with a carriage return to force a new line, (2) runs the compiled PoC binary (expected as ./cdsjobexp) to move the log into /etc/sudoers.d/myfile, and (3) validates escalation by running `sudo touch /tmp/vmwarebeware` and checking the file is owned by UID 0. Main capability: local privilege escalation to root via unauthorized/insufficiently authorized XPC access to a privileged helper’s file-move functionality, enabling sudoers injection. No external network C2 is present; the key ‘endpoints’ are the Mach service name and sensitive filesystem paths.
