CVE-2022-31183
Good to know:
Date: August 1, 2022
fs2 is a compositional, streaming I/O library for Scala. When establishing a server-mode "TLSSocket" using "fs2-io" on Node.js, the parameter "requestCert = true" is ignored, peer certificate verification is skipped, and the connection proceeds. The vulnerability is limited to: 1. "fs2-io" running on Node.js. The JVM TLS implementation is completely independent. 2. "TLSSocket"s in server-mode. Client-mode "TLSSocket"s are implemented via a different API. 3. mTLS as enabled via "requestCert = true" in "TLSParameters". The default setting is "false" for server-mode "TLSSocket"s. It was introduced with the initial Node.js implementation of fs2-io in 3.1.0. A patch is released in v3.2.11. The requestCert = true parameter is respected and the peer certificate is verified. If verification fails, a SSLException is raised. If using an unpatched version on Node.js, do not use a server-mode TLSSocket with requestCert = true to establish a mTLS connection.
