CVE-2024-55886

OpenSearch Data Prepper is a component of the OpenSearch project that accepts, filters, transforms, enriches, and routes data at scale. A vulnerability exists in the OpenTelemetry Logs source in Data Prepper starting inversion 2.1.0 and prior to version 2.10.2 where some custom authentication plugins will not perform authentication. This allows unauthorized users to ingest OpenTelemetry Logs data under certain conditions. This vulnerability does not affect the built-in http_basic authentication provider in Data Prepper. Pipelines which use the http_basic authentication provider continue to require authentication. The vulnerability exists only for custom implementations of Data Prepper’s GrpcAuthenticationProvider authentication plugin which implement the getHttpAuthenticationService() method instead of getAuthenticationInterceptor(). Data Prepper 2.10.2 contains a fix for this issue. For those unable to upgrade, one may use the built-in http_basic authentication provider in Data Prepper and/or add an authentication proxy in front of one's Data Prepper instances running the OpenTelemetry Logs source.

Frequently Asked Questions

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.

CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.

A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.

Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.

Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.

SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
