CVE-2026-45685: CWE-20: Improper Input Validation in open-telemetry opentelemetry-ebpf-instrumentation
OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.1.0 to before version 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated, so a single crafted message can terminate telemetry collection for the affected process or node. This issue has been patched in version 0.9.0.
AI Analysis
Technical Summary
The vulnerability in open-telemetry's opentelemetry-ebpf-instrumentation affects versions 0.1.0 through before 0.9.0. It arises from improper input validation (CWE-20) in the MongoDB TCP parser, which processes raw network payloads before full validation. Malformed MongoDB wire messages can trigger uncaught panics, causing the telemetry agent to crash and resulting in denial of service. The vulnerability has a CVSS 3.1 score of 7.5, indicating high severity. The issue was addressed and patched in version 0.9.0.
Potential Impact
A remote unauthenticated attacker can send crafted MongoDB wire messages to the affected telemetry agent, causing it to panic and crash. This results in denial of service by terminating telemetry collection for the affected process or node. There is no impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
Upgrade opentelemetry-ebpf-instrumentation to version 0.9.0 or later, where this vulnerability has been patched. Patch status is confirmed by the vendor advisory indicating the fix in version 0.9.0. No other mitigations are specified.
