CVE-2015-4719
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe client API authentication mechanism in Pexip Infinity before 10 allows remote attackers to gain privileges via a crafted request.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe client API authentication mechanism in Pexip Infinity versions before version 10 contains a flaw that allows remote attackers to craft requests that bypass authentication controls and gain elevated privileges on the platform.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Pexip Infinity versionAccess the Pexip Infinity admin interface or use the command line management tool to retrieve the current software version. This is typically found in the system status or about section of the admin GUI.Affected if The installed version is any release before version 10 (versions 9.x, 8.x, 7.x, etc.)
-
Confirm the client API endpoint is accessibleVerify that the Pexip client API service is running and reachable. This API is typically exposed on standard HTTPS ports for video conferencing client connections.Affected if The client API service is exposed and reachable from untrusted networks
-
Check for signs of unauthorized elevated accessReview Pexip Infinity audit logs and admin access logs for any authentication anomalies, privilege escalation events, or API calls that succeeded without proper credential validation.Affected if Any audit entries show successful API calls from sources that should have failed authentication or show unexpected admin-level actions
-
Review authentication configuration for the client APIExamine the Pexip Infinity authentication settings specifically for the client API subsystem to confirm whether the vulnerable authentication mechanism is in use.Affected if The client API is configured to use the legacy authentication mechanism present in pre-v10 releases
The environment is affected if the installed Pexip Infinity version is below version 10 and the client API is accessible, as the vulnerability allows authentication bypass in the client API authentication mechanism.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade Pexip Infinity to version 10 or later to obtain the patched authentication mechanism.
Pexip Infinity version 10
- Verify current Pexip Infinity version by checking the admin interface or system information
- Review Pexip upgrade documentation at docs.pexip.com for upgrade prerequisites
- Create a complete backup of the current system configuration
- Follow the standard Pexip Infinity upgrade procedure to version 10 or later
- Verify the upgrade was successful and the client API authentication mechanism is functioning correctly
