The Command Line Interface (aka Server CLI or administration interface) in the master process in the reverse proxy server in Varnish before 2.1.0 does not require authentication for commands received through a TCP port, which allows remote attackers to (1) execute arbitrary code via a vcl.inline directive that provides a VCL configuration file containing inline C code; (2) change the ownership of the master process via param.set, stop, and start directives; (3) read the initial line of an arbitrary file via a vcl.load directive; or (4) conduct cross-site request forgery (CSRF) attacks that leverage a victim's location on a trusted network and improper input validation of directives. NOTE: the vendor disputes this report, saying that it is "fundamentally misguided and pointless.

Security readout for executives and security teams

This CVE concerns an unauthenticated Varnish administration interface in versions before 2.1.0. If the CLI TCP port is reachable by attackers, they may be able to perform powerful administrative actions. The vendor disputed the report, and the sources do not show active exploitation. Exposure is most likely where old Varnish deployments expose the Server CLI or administration interface beyond tightly controlled management hosts. Public internet exposure would materially increase concern, but the bundle provides no prevalence data. Treat as a targeted legacy exposure review, not a confirmed emergency. Prioritize if the organization still runs pre-2.1.0 Varnish or exposes administrative interfaces across untrusted networks. Mitigation focus: Identify any Varnish deployments older than 2.1.0.; Apply vendor or distribution updates where guidance applies.; Restrict the CLI administration interface to trusted management paths only..
