Turning a boring file move into a privilege escalation on Mac | pwn.win
While poking around Parallels Desktop I found a script which is invoked by a setuid-root binary, which has the following snippet: local prl_dir="${usr_home}/Library/Parallels" if [ -e "$prl_dir" -a ! -d "$prl_dir" ]; then log warning "'${prl_dir}' is not a directory. Renaming it." mv -f "$prl_dir"{,~} continue fi Here ${usr_home} represents the home directory of the user for which Parallels Desktop is installed. The code says if ~/Library/Parallels exists and is not a directory then move it to ~/Library/Parallels~, presumably to back it up before creating this path as a directory.

iLeakage
We present iLeakage, a transient execution side channel targeting the Safari web browser present on Macs, iPads and iPhones. iLeakage shows that the Spectre attack is still relevant and exploitable, even after nearly 6 years of effort to mitigate it since its discovery. We show how an attacker can induce Safari to render an arbitrary webpage, subsequently recovering sensitive information present within it using speculative execution. In particular, we demonstrate how Safari allows a malicious webpage to recover secrets from popular high-value targets, such as Gmail inbox content. Finally, we demonstrate the recovery of passwords, in case these are autofilled by credential managers.
Hackers can force iOS and macOS browsers to divulge passwords and much more
iLeakage is practical and requires minimal resources. A patch isn't (yet) available.
