CVE-2024-45810

Описание

Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy will crash when the http async client is handling sendLocalReply under some circumstance, e.g., websocket upgrade, and requests mirroring. The http async client will crash during the sendLocalReply() in http async client, one reason is http async client is duplicating the status code, another one is the destroy of router is called at the destructor of the async stream, while the stream is deferred deleted at first. There will be problems that the stream decoder is destroyed but its reference is called in router.onDestroy(), causing segment fault. This will impact ext_authz if the upgrade and connection header are allowed, and request mirrorring. This issue has been addressed in versions 1.31.2, 1.30.6, 1.29.9, and 1.28.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

A flaw was found in Envoy. Envoy will crash when the http async client is handling sendLocalReply under some circumstances, such as websocket upgrade and requests mirroring. The http async client will crash during the sendLocalReply() in http async client if the http async client is duplicating the status code or if the destruction of the router is called at the destructor of the async stream while the stream is deferred or deleted. This issue occurs when the stream decoder is destroyed but it's reference is called in router.onDestroy(), causing a segment fault. This will impact ext_authz if the upgrade and connection header are allowed.
