In the case of OpenShift Container Platform, this would be restricted within each individual container. Additionally, this is in alignment with upstream\u0027s (the Prometheus project) impact rating.\n\nWithin regulated environments, a combination of the following controls acts as a significant barrier to successful exploitation of a CWE-772: Missing Release of Resource after Effective Lifetime and therefore downgrades the severity of this particular CVE from Moderate to Low.\n\nBaseline configurations enforce strict resource allocation and lifecycle management policies, ensuring that memory, CPU, and storage resources are efficiently released when no longer needed. The platform continuously monitors resource allocation and usage across compute environments and workloads, leveraging built-in quota and limit mechanisms to prevent resource exhaustion caused by unreleased objects. Real-time system monitoring detects abnormal consumption patterns, such as unused resource retention or elevated usage levels, enabling timely remediation and preventing compounding impacts.",

CVE-2022-21698 (GCVE-0-2022-21698)

Vulnerability from cvelistv5 – Published: 2022-02-15 00:00 – Updated: 2025-04-23 19:05

Summary

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.

Severity ?

          "value": "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."
