CVE-2016-7099: n/a vulnerability

CVE-2016-7099: The tls.checkServerIdentity function in Node.js 0.10.x before 0.10.47, 0.12.x before 0.12.16, 4.x before 4....

The tls.checkServerIdentity function in Node.js 0.10.x before 0.10.47, 0.12.x before 0.12.16, 4.x before 4.6.0, and 6.x before 6.7.0 does not properly handle wildcards in name fields of X.509 certificates, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

Security readout for executives and security teams

Older Node.js releases could accept a maliciously crafted TLS certificate as valid for the wrong server name. An attacker positioned between a Node.js client and a server could spoof the server, undermining confidentiality and trust in outbound HTTPS or TLS connections. Exposure is most likely in legacy applications still running vulnerable Node.js versions and relying on built-in TLS hostname verification for outbound connections. Current supported Node.js lines are not identified as affected in the provided sources. Treat as high priority if any legacy Node.js runtime remains in production. The business risk is silent server impersonation on TLS connections, but urgency depends on confirmed use of affected versions. Mitigation focus: Upgrade affected Node.js runtimes to the fixed versions or later.; Use supported Node.js releases wherever possible.; Check Red Hat and SUSE advisories for distro package fixes..
