Pomelo allows external control of critical state data
CVE-2019-18954 · GHSA-4x6v-rwh4-55jw
- Affected
- npm pomelo < 2.2.7
- Fixed in
- 2.2.7· Vendor fix available
- Issue
- Pomelo v2.2.5 allows external control of critical state data. A malicious user input can corrupt arbitrary methods and attributes in template/game-server/app/servers/connector/handler/entryHandler.js because certain internal attributes can be overwritten via a conflicting name. Hence, a malicious attacker can manipulate internal attributes by adding additional attributes to user input.
Recommended action: Upgrade to 2.2.7 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
