CVE-2023-43810 1 Opentelemetry 1 Opentelemetry 2024-09-19 7.5 High
OpenTelemetry, also known as OTel for short, is a vendor-neutral open-source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, logs. Autoinstrumentation out of the box adds the label `http_method` that has unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent. HTTP method for requests can be easily set by an attacker to be random and long. In order to be affected program has to be instrumented for HTTP handlers and does not filter any unknown HTTP methods on the level of CDN, LB, previous middleware, etc. This issue has been patched in version 0.41b0.
CVE-2023-47108 2 Opentelemetry, Redhat 5 Opentelemetry, Acm, Openshift and 2 more 2024-09-03 7.5 High
OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Prior to version 0.46.0, the grpc Unary Server Interceptor out of the box adds labels `net.peer.sock.addr` and `net.peer.sock.port` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent. An attacker can easily flood the peer address and port for requests. Version 0.46.0 contains a fix for this issue. As a workaround to stop being affected, a view removing the attributes can be used. The other possibility is to disable grpc metrics instrumentation by passing `otelgrpc.WithMeterProvider` option with `noop.NewMeterProvider`.
CVE-2024-45043 1 Opentelemetry 1 Opentelemetry Collector Contrib 2024-08-29 5.3 Medium
The OpenTelemetry Collector module AWS firehose receiver is for ingesting AWS Kinesis Data Firehose delivery stream messages and parsing the records received based on the configured record type. `awsfirehosereceiver` allows unauthenticated remote requests, even when configured to require a key. OpenTelemetry Collector can be configured to receive CloudWatch metrics via an AWS Firehose Stream. Firehose sets the header `X-Amz-Firehose-Access-Key` with an arbitrary configured string. The OpenTelemetry Collector awsfirehosereceiver can optionally be configured to require this key on incoming requests. However, when this is configured it **still accepts incoming requests with no key**. Only OpenTelemetry Collector users configured with the “alpha” `awsfirehosereceiver` module are affected. This module was added in version v0.49.0 of the “Contrib” distribution (or may be included in custom builds). There is a risk of unauthorized users writing metrics. Carefully crafted metrics could hide other malicious activity. There is no risk of exfiltrating data. It’s likely these endpoints will be exposed to the public internet, as Firehose does not support private HTTP endpoints. A fix was introduced in PR #34847 and released with v0.108.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-42368 1 Opentelemetry 1 Opentelemetry Collector Contrib 2024-08-14 6.5 Medium
OpenTelemetry, also known as OTel, is a vendor-neutral open source Observability framework for instrumenting, generating, collecting, and exporting telemetry data such as traces, metrics, and logs. The bearertokenauth extension's server authenticator performs a simple, non-constant time string comparison of the received & configured bearer tokens. This impacts anyone using the `bearertokenauth` server authenticator. Malicious clients with network access to the collector may perform a timing attack against a collector with this authenticator to guess the configured token, by iteratively sending tokens and comparing the response time. This would allow an attacker to introduce fabricated or bad data into the collector's telemetry pipeline. The observable timing vulnerability was fixed by using constant-time comparison in 0.107.0
CVE-2023-45142 2 Opentelemetry, Redhat 7 Opentelemetry, Acm, Ceph Storage and 4 more 2024-08-02 7.5 High
OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. A handler wrapper out of the box adds labels `http.user_agent` and `http.method` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent to it. HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses `httpconv.ServerRequest` that records every value for HTTP `method` and `User-Agent`. In order to be affected, a program has to use the `otelhttp.NewHandler` wrapper and not filter any unknown HTTP methods or User agents on the level of CDN, LB, previous middleware, etc. Version 0.44.0 fixed this issue when the values collected for attribute `http.request.method` were changed to be restricted to a set of well-known values and other high cardinality attributes were removed. As a workaround to stop being affected, `otelhttp.WithFilter()` can be used, but it requires manual careful configuration to not log certain requests entirely. For convenience and safe usage of this library, it should by default mark with the label `unknown` non-standard HTTP methods and User agents to show that such requests were made but do not increase cardinality. In case someone wants to stay with the current behavior, library API should allow to enable it.
CVE-2024-36129 2 Opentelemetry, Redhat 5 Configgrpc, Confighttp, Opentelemetry and 2 more 2024-08-02 8.2 High
The OpenTelemetry Collector offers a vendor-agnostic implementation on how to receive, process and export telemetry data. An unsafe decompression vulnerability allows unauthenticated attackers to crash the collector via excessive memory consumption. OTel Collector version 0.102.1 fixes this issue. It is also fixed in the confighttp module version 0.102.0 and configgrpc module version 0.102.1.
