Vulnerability from github – Published: 2022-02-16 22:26 – Updated: 2022-02-25 15:41
VLAI
Summary
Uncontrolled Resource Consumption in promhttp
Details

This is the Go client library for Prometheus. It has two separate parts, one for instrumenting application code, and one for creating clients that talk to the Prometheus HTTP API. 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.

Impact

HTTP server susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods.

Affected Configuration

In order to be affected, an instrumented software must

  • Use any of promhttp.InstrumentHandler* middleware except RequestsInFlight.
  • Do not filter any specific methods (e.g GET) before middleware.
  • Pass metric with method label name to our middleware.
  • Not have any firewall/LB/proxy that filters away requests with unknown method.

Patches

  • https://github.com/prometheus/client_golang/pull/962
  • https://github.com/prometheus/client_golang/pull/987

Workarounds

If you cannot upgrade to v1.11.1 or above, in order to stop being affected you can:

  • Remove method label name from counter/gauge you use in the InstrumentHandler.
  • Turn off affected promhttp handlers.
  • Add custom middleware before promhttp handler that will sanitize the request method given by Go http.Request.
  • Use a reverse proxy or web application firewall, configured to only allow a limited set of methods.

GHSA-CP3F-3WC5-J85W

Vulnerability from github – Published: 2024-10-23 18:33 – Updated: 2025-10-22 00:33
VLAI
Details

A vulnerability in the Remote Access VPN (RAVPN) service of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) of the RAVPN service.

This vulnerability is due to resource exhaustion. An attacker could exploit this vulnerability by sending a large number of VPN authentication requests to an affected device. A successful exploit could allow the attacker to exhaust resources, resulting in a DoS of the RAVPN service on the affected device. Depending on the impact of the attack, a reload of the device may be required to restore the RAVPN service. Services that are not related to VPN are not affected.

Cisco Talos discussed these attacks in the blog post Large-scale brute-force activity targeting VPNs, SSH services with commonly used login credentials.

Summary
OpenStack Neutron Denial of Service vulnerability
Details

An issue was discovered in the routes middleware in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. By making API requests involving nonexistent controllers, an authenticated user may cause the API worker to consume increasing amounts of memory, resulting in API performance degradation or denial of service.

Mitigation MIT-3
Requirements

Strategy: Language Selection

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
Mitigation
Implementation

It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free resources in a function. If you allocate resources that you intend to free upon completion of the function, you must be sure to free the resources at all exit points for that function including error conditions.

Mitigation MIT-47
Operation Architecture and Design

Strategy: Resource Limitation

  • Use resource-limiting settings provided by the operating system or environment. For example, when managing system resources in POSIX, setrlimit() can be used to set limits for certain types of resources, and getrlimit() can determine how many resources are available. However, these functions are not available on all operating systems.
  • When the current levels get close to the maximum that is defined for the application (see CWE-770), then limit the allocation of further resources to privileged users; alternately, begin releasing resources for less-privileged users. While this mitigation may protect the system from attack, it will not necessarily stop attackers from adversely impacting other users.
  • Ensure that the application performs the appropriate error checks and error handling in case resources become unavailable (CWE-703).
CAPEC-469: HTTP DoS

An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
