CVE-2020-24615
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 · uneditedPexip Infinity before 24.1 has Improper Input Validation, leading to temporary denial of service via SIP.
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 confidencePexip Infinity versions before 24.1 contain an improper input validation vulnerability in the SIP (Session Initiation Protocol) component. The vulnerability allows attackers to cause a temporary denial of service by sending specially crafted SIP messages that the system fails to validate properly.

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 installed Pexip Infinity versionAccess the Pexip Infinity admin interface and navigate to the System > About section, or use the CLI command 'show system-information' to display the currently installed version.Affected if The displayed version number is less than 24.1 (for example, 24.0, 23.x, or earlier releases).
-
Confirm SIP component is enabledIn the Pexip Infinity admin interface, navigate to SIP > General Settings or Locations > [select location] > SIP to verify that SIP functionality is enabled for the deployment.Affected if SIP is enabled and configured for any location or call routing rule.
-
Verify SIP listening configurationCheck the SIP listening addresses and ports configured under System > Transport or SIP > Listening Addresses. Confirm the system is accepting SIP connections on the configured ports (typically 5060/5061).Affected if The system has SIP listeners active and accepting connections.
-
Review SIP log for malformed messagesAccess the Pexip Infinity logs via the admin interface or CLI (using 'show log sip' or reviewing the sip.log file). Look for entries indicating malformed SIP messages, parsing errors, or unexpected message rejections.Affected if SIP logs show evidence of malformed SIP messages being processed or causing errors, particularly before any upgrade to 24.1.
The environment is affected if Pexip Infinity version is below 24.1 AND the SIP component is enabled and configured to accept SIP traffic.
