Title
Cockpit-files: cockpit-files: arbitrary file ownership and permission modification via symlink race condition
Summary
A flaw was found in cockpit-files. This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions. By manipulating directory entries and winning this race, the attacker can redirect these operations to unintended files. This could lead to unauthorized changes in file ownership and permissions on arbitrary files, potentially compromising system integrity and availability by altering system or application states or rendering services unusable.

Exploitability is substantially reduced when privileged Cockpit sessions do not operate on attacker-writable directories."

This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions.

This could lead to unauthorized changes in file ownership and permissions on arbitrary files, potentially compromising system integrity and availability by altering system or application states or rendering services unusable."
