GHSA-CJR9-MR35-7XH6

Vulnerability from github – Published: 2023-04-13 17:53 – Updated: 2023-04-14 21:35

Summary

SpiceDB binding metrics port to untrusted networks and can leak command-line flags

Details

Background

The spicedb serve command contains a flag named --grpc-preshared-key which is used to protect the gRPC API from being accessed by unauthorized requests. The values of this flag are to be considered sensitive, secret data.

The /debug/pprof/cmdline endpoint served by the metrics service (defaulting running on port 9090) reveals the command-line flags provided for debugging purposes. If a password is set via the --grpc-preshared-key then the key is revealed by this endpoint along with any other flags provided to the SpiceDB binary.

Impact

All deployments abiding by the recommended best practices for production usage are NOT affected: - Authzed's SpiceDB Serverless - Authzed's SpiceDB Dedicated - SpiceDB Operator

Users configuring SpiceDB via environment variables are NOT affected.

Users MAY be affected if they expose their metrics port to an untrusted network and are configuring --grpc-preshared-key via command-line flag.

Workarounds

To workaround this issue you can do one of the following:

Configure the preshared key via an environment variable (e.g. SPICEDB_GRPC_PRESHARED_KEY=yoursecret spicedb serve)
Reconfigure the --metrics-addr flag to bind to a trusted network (e.g. --metrics-addr=localhost:9090)
Disable the metrics service via the flag (e.g. --metrics-enabled=false)
Adopt one of the recommended deployment models: Authzed's managed services or the SpiceDB Operator

CVE-2023-29193 (GCVE-0-2023-29193)

Vulnerability from cvelistv5 – Published: 2023-04-14 19:01 – Updated: 2025-02-06 18:42

Title

SpiceDB binding metrics port to untrusted networks and can leak command-line flags

Summary

SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions. The `spicedb serve` command contains a flag named `--grpc-preshared-key` which is used to protect the gRPC API from being accessed by unauthorized requests. The values of this flag are to be considered sensitive, secret data. The `/debug/pprof/cmdline` endpoint served by the metrics service (defaulting running on port `9090`) reveals the command-line flags provided for debugging purposes. If a password is set via the `--grpc-preshared-key` then the key is revealed by this endpoint along with any other flags provided to the SpiceDB binary. This issue has been fixed in version 1.19.1. ### Impact All deployments abiding by the recommended best practices for production usage are **NOT affected**: - Authzed's SpiceDB Serverless - Authzed's SpiceDB Dedicated - SpiceDB Operator Users configuring SpiceDB via environment variables are **NOT affected**. Users **MAY be affected** if they expose their metrics port to an untrusted network and are configuring `--grpc-preshared-key` via command-line flag. ### Patches TODO ### Workarounds To workaround this issue you can do one of the following: - Configure the preshared key via an environment variable (e.g. `SPICEDB_GRPC_PRESHARED_KEY=yoursecret spicedb serve`) - Reconfigure the `--metrics-addr` flag to bind to a trusted network (e.g. `--metrics-addr=localhost:9090`) - Disable the metrics service via the flag (e.g. `--metrics-enabled=false`) - Adopt one of the recommended deployment models: [Authzed's managed services](https://authzed.com/pricing) or the [SpiceDB Operator](https://github.com/authzed/spicedb-operator) ### References - [GitHub Security Advisory issued for SpiceDB](https://github.com/authzed/spicedb/security/advisories/GHSA-cjr9-mr35-7xh6) - [Go issue #22085](https://github.com/golang/go/issues/22085) for documenting the risks of exposing pprof to the internet - [Go issue #42834](https://github.com/golang/go/issues/42834) discusses preventing pprof registration to the default serve mux - [semgrep rule go.lang.security.audit.net.pprof.pprof-debug-exposure](https://semgrep.dev/r?q=go.lang.security.audit.net.pprof) checks for a variation of this issue ### Credit We'd like to thank Amit Laish, a security researcher at GE Vernova for responsibly disclosing this vulnerability.
