Description

Wings is Pterodactyl's server control plane. Affected versions are subject to a vulnerability which can be used to create new files and directory structures on the host system that previously did not exist, potentially allowing attackers to change their resource allocations, promote their containers to privileged mode, or potentially add ssh authorized keys to allow the attacker access to a remote shell on the target machine. In order to use this exploit, an attacker must have an existing "server" allocated and controlled by the Wings Daemon. This vulnerability has been resolved in version `v1.11.3` of the Wings Daemon, and has been back-ported to the 1.7 release series in `v1.7.3`. Anyone running `v1.11.x` should upgrade to `v1.11.3` and anyone running `v1.7.x` should upgrade to `v1.7.3`. There are no known workarounds for this vulnerability. ### Workarounds None at this time.

• CWE-59Improper Link Resolution Before File Access ('Link Following')The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
