Name of the Vulnerable Software and Affected Versions
OpenTelemetry eBPF Instrumentation versions 0.1.0 through 0.8.0
Description
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, meaning a single crafted message can terminate telemetry collection for the affected process or node. Technical details include slice-bounds panics in the
parseOpMessage() and parseSections() functions when processing truncated OP MSG packets or malformed document-sequence sections, as well as a runtime panic in the parseFirstField() function due to an unchecked type assertion on field.Value when processing malformed BSON documents.Recommendations
Update to version 0.9.0 or later.
As a temporary workaround, restrict the telemetry agent from processing MongoDB traffic from untrusted or partially trusted clients to minimize the risk of exploitation.
