CVE-2022-21698 - High Severity Vulnerability
Prometheus instrumentation library for Go applications
Dependency Hierarchy: - github.com/xmidt-org/capacityset-v0.1.1 (Root Library) - github.com/xmidt-org/webpa-common-v1.11.5 - :x: **github.com/prometheus/client_golang-v1.11.0** (Vulnerable Library)
Found in HEAD commit: d07468c0219eb7e3ba2c006c717d1cf9b49baf88
Found in base branch: main
client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods.
