openhpi/Makefile.am in OpenHPI before 3.6.0 uses world-writable permissions for /var/lib/openhpi directory, which allows local users, when quotas are not properly setup, to fill the filesystem hosting /var/lib and cause a denial of service (disk consumption).

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Potential Mitigations

  • Mitigation of resource exhaustion attacks requires that the target system either:

  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.

  • The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
