Incorrect access control mechanisms in Citrix Receiver Desktop Lock 4.5 allow an attacker to bypass the authentication requirement by leveraging physical access to a VDI for temporary disconnection of a LAN cable. NOTE: as of 20161208, the vendor could not reproduce the issue, stating "the researcher was unable to provide us with information that would allow us to confirm the behaviour and, despite extensive investigation on test deployments of supported products, we were unable to reproduce the behaviour as he described. The researcher has also, despite additional requests for information, ceased to respond to us."

Security readout for executives and security teams

This CVE describes a reported authentication bypass in Citrix Receiver Desktop Lock 4.5. The claimed issue requires physical access to a VDI endpoint and involves temporarily interrupting network connectivity. Citrix reportedly could not reproduce the behavior, so the evidence base is incomplete. Exposure is most plausible where Citrix Receiver Desktop Lock 4.5 is deployed on physically accessible VDI, kiosk, lab, or shared-workstation endpoints. Prioritize review if the organization uses Citrix Desktop Lock on shared or public VDI endpoints. Otherwise, treat as an evidence-limited legacy finding and confirm whether the affected product remains in service. Mitigation focus: Identify whether Citrix Receiver Desktop Lock 4.5 is still deployed.; Restrict physical access to affected VDI endpoints and network cabling.; Check current Citrix guidance for supported versions and remediation advice..
