CVE-2024-27102: Pterodactyl Wings vulnerable to improper isolation of server file access
Wings is the server control plane for Pterodactyl Panel.
CVSS 10.0 Critical EPSS 0.5% · p45
Should you act?
Critical, preconditions apply
Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.5%, percentile 45: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 45% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
github.com/pterodactyl/wings(Go) < 1.11.9, fixed in 1.11.9. Check your lockfile, including transitive dependencies.
What it is
Wings is the server control plane for Pterodactyl Panel. This vulnerability impacts anyone running the affected versions of Wings. The vulnerability can potentially be used to access files and directories on the host system. The full scope of impact is exactly unknown, but reading files outside of a server's base directory (sandbox root) is possible. In order to use this exploit, an attacker must have an existing "server" allocated and controlled by Wings. Details on the exploitation of this vulnerability are embargoed until March 27th, 2024 at 18:00 UTC. In order to mitigate this vulnerability, a full rewrite of the entire server filesystem was necessary. Because of this, the size of the patch is massive, however effort was made to reduce the amount of breaking changes. Users are advised to update to version 1.11.9. There are no known workarounds for this vulnerability.
