Source: CVE Database V5
Vendor/Project: grpc
Product: grpc-node

Description

@grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming HTTP/2 stream initiation can cause a server process created using @grpc/grpc-js to crash. This issue is fixed in versions 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4.

Technical Analysis

@grpc/grpc-js, the JavaScript implementation of gRPC core functionality without a C++ addon, contains a vulnerability identified as CWE-248 (Uncaught Exception). In affected versions prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid HTTP/2 stream initiation can trigger an uncaught exception, causing the server process to crash. This results in a denial-of-service impact. The vulnerability has been fixed in the stated versions.

Potential Impact

Successful exploitation causes the grpc-node server process to crash due to an uncaught exception triggered by invalid HTTP/2 stream initiation. This leads to denial of service (DoS) with no confidentiality or integrity impact reported.

Mitigation Recommendations

Upgrade grpc-node to one of the fixed versions: 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, or 1.14.4. Patch status is confirmed by the version information in the advisory. No other mitigation or workaround is indicated.
