DirectAdmin creates temporary files in an insecure manner.
An attacker with local access could potentially exploit this issue to perform symbolic link attacks to overwrite arbitrary attacker-specified files. This could facilitate a complete compromise of the affected computer.
Versions prior to DirectAdmin 1.33.4 are vulnerable.
