CVE-2025-32095 is a vulnerability identified in Pexip Infinity, a widely used video conferencing and collaboration platform. The flaw stems from improper input validation in the signalling protocol handling, classified under CWE-617 (Reachable Assertion). Specifically, the software contains assertions that are reachable and can be triggered by crafted signalling messages sent remotely without authentication or user interaction. When exploited, the assertion failure causes the Pexip Infinity service to abort unexpectedly, leading to a denial of service condition. The CVSS v3.1 base score is 7.5, reflecting high severity due to network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability affects all versions before 37.0, and no patches are currently linked, indicating that a fix is anticipated but not yet released. Although the vulnerability does not compromise confidentiality or integrity, the availability impact can disrupt critical communication services, especially in enterprise environments relying on Pexip for real-time collaboration. No known exploits have been observed in the wild, but the ease of exploitation and potential impact warrant immediate attention. The vulnerability highlights the importance of robust input validation in signalling protocols to prevent assertion failures that can crash services.

For European organizations, the primary impact is denial of service on Pexip Infinity platforms, which can disrupt video conferencing, remote meetings, and unified communications. This can affect business continuity, especially in sectors like finance, healthcare, government, and critical infrastructure where reliable communication is essential. The disruption could also impact cross-border collaboration within the EU and with external partners. Since the vulnerability requires no authentication, attackers can exploit it remotely, increasing the risk of widespread service outages. Organizations heavily dependent on Pexip Infinity for daily operations may face operational delays, loss of productivity, and potential reputational damage. The lack of confidentiality or integrity impact limits data breach concerns, but availability loss alone can have significant operational consequences. The absence of known exploits in the wild provides a window for proactive mitigation before active attacks emerge.

1. Monitor network traffic for unusual or malformed signalling messages targeting Pexip Infinity services to detect potential exploitation attempts. 2. Implement network-level protections such as firewalls or intrusion prevention systems (IPS) with signatures or heuristics to block suspicious signalling traffic. 3. Restrict access to Pexip Infinity signalling ports to trusted networks and users where feasible, using network segmentation and access control lists. 4. Prepare for rapid deployment of vendor patches by establishing a patch management process specifically for Pexip Infinity once updates become available. 5. Conduct regular backups and ensure failover or redundancy mechanisms are in place to maintain service availability during potential DoS incidents. 6. Engage with Pexip support or vendor channels to receive timely vulnerability disclosures and remediation guidance. 7. Educate IT and security teams about this vulnerability to increase awareness and readiness for incident response. 8. Consider deploying application-layer gateways or proxies that can validate signalling messages before forwarding them to Pexip Infinity servers.
