A fix is available — apply it.

Wings is the server control plane for the Pterodactyl game-server management panel. In versions up to and including 1.13.2, the SFTP write path does not enforce a server's disk quota during a transfer, allowing a tenant with SFTP write access to a single server to exhaust the host node's physical disk and take down every server on it. Wings checks available space only once, as a boolean, when the write handle is opened, using a stale cached usage value and without knowing the size of the incoming data, and it then returns a raw, unaccounted file handle that is never re-checked as the transfer proceeds. A single upload can therefore be written without bound, far beyond the configured disk limit, until the node's disk is full, and because a server stopped for exceeding its limit is not treated as suspended, SFTP writes are still accepted even after the quota is already exceeded. This issue is fixed in version 1.13.3.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
