CVE-2021-32794 — ArchiSteamFarm is a C# application with primary purpose of idling Steam cards from multiple accounts simultaneously

High CVSS 7.5

ArchiSteamFarm is a C# application with primary purpose of idling Steam cards from multiple accounts simultaneously. Due to a bug in ASF code `POST /Api/ASF` ASF API endpoint responsible for updating global ASF config incorrectly removed `IPCPassword` from the resulting config when the caller did not specify it explicitly. Due to the above, it was possible for the user to accidentally remove `IPCPassword` security measure from his IPC interface when updating global ASF config, which exists as part of global config update functionality in ASF-ui. Removal of `IPCPassword` possesses a security risk, as unauthorized users may in result access the IPC interface after such modification. The issue is patched in ASF V5.1.2.4 and future versions. We recommend to manually verify that `IPCPassword` is specified after update, and if not, set it accordingly. In default settings, ASF is configured to allow IPC access from `localhost` only and should not affect majority of users.

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
