gRPC has a vulnerability linked to hpack table accounting errors, causing potential unwanted disconnects between clients and servers. Identified vectors include unbounded memory buffering and CPU consumption within the HPACK parser, leading to denial-of-service (DOS) attacks. The CPU issue stems from excessive copying, resulting in inefficient parsing. Memory issues arise from delayed header size checks, allowing large strings to be buffered, and a quirk in HPACK's integer encoding, permitting infinite zero-padding. Additionally, metadata overflow checks per frame could enable infinite buffering, compromising gRPC's stability and security.

When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests from the proxy being interpreted as containing headers from different proxy clients - leading to an information leak that can be used for privilege escalation or data exfiltration.

Grpcio 1.53.2, 1.54.3, 1.55.3 and 1.56.2 include a fix for CVE-2023-4785: Lack of error handling in the TCP server in Google's gRPC starting version 1.23 on posix-compatible platforms (ex. Linux) allows an attacker to cause a denial of service by initiating a significant number of connections with the server. Note that gRPC C++ Python, and Ruby are affected, but gRPC Java, and Go are NOT affected.

There exists an vulnerability causing an abort() to be called in gRPC.  The following headers cause gRPC's C++ implementation to abort() when called via http2: te: x (x != trailers) :scheme: x (x != http, https) grpclb_client_stats: x (x == anything) On top of sending one of those headers, a later header must be sent that gets the total header size past 8KB.

gRPC has a vulnerability linked to hpack table accounting errors, causing potential unwanted disconnects between clients and servers. Identified vectors include unbounded memory buffering and CPU consumption within the HPACK parser, leading to denial-of-service (DOS) attacks. The CPU issue stems from excessive copying, resulting in inefficient parsing. Memory issues arise from delayed header size checks, allowing large strings to be buffered, and a quirk in HPACK's integer encoding, permitting infinite zero-padding. Additionally, metadata overflow checks per frame could enable infinite buffering, compromising gRPC's stability and security.

When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and a backend, this could lead to requests from the proxy being interpreted as containing headers from different proxy clients - leading to an information leak that can be used for privilege escalation or data exfiltration.
