Pterodactyl's improper resource locking allows raced queries to create more resources than alloted

Pterodactyl is a free, open-source game server management panel. Pterodactyl implements rate limits that are applied to the total number of resources (e.g. databases, port allocations, or backups) that can exist for an individual server. These resource limits are applied on a per-server basis, and validated during the request cycle. However, in versions prior to 1.12.0, it is possible for a malicious user to send a massive volume of requests at the same time that would create more resources than the server is allotted. This is because the validation occurs early in the request cycle and does not lock the target resource while it is processing. As a result sending a large volume of requests at the same time would lead all of those requests to validate as not using any of the target resources, and then all creating the resources at the same time. As a result a server would be able to create more databases, allocations, or backups than configured. A malicious user is able to deny resources to other users on the system, and may be able to excessively consume the limited allocations for a node, or fill up backup space faster than is allowed by the system. Version 1.12.0 fixes the issue.

Pterodactyl Panel 安全漏洞

Pterodactyl Panel是Pterodactyl开源的一个免费的开源游戏服务器管理面板。 Pterodactyl Panel 1.12.0之前版本存在安全漏洞，该漏洞源于资源限制验证发生在请求周期早期且未在处理时锁定目标资源，可能导致恶意用户发送大量并发请求创建超出分配的资源，造成拒绝资源或过度消耗节点分配和备份空间。
