CVE-2025-32096 is a vulnerability classified under CWE-617 (Reachable Assertion) affecting Pexip Infinity versions 33.0 through 37.0 before 37.1. The flaw arises from improper input validation in the signaling protocol, which is responsible for managing session initiation and control in the Pexip video conferencing platform. An attacker can send specially crafted signaling messages that cause the software to hit an assertion failure—a programming check that unexpectedly fails—leading to an immediate software abort. This results in a denial of service condition where the affected Pexip Infinity server or service becomes unavailable. The vulnerability is remotely exploitable without requiring any authentication or user interaction, increasing the risk of automated or widespread attacks. While the vulnerability does not compromise data confidentiality or integrity, the loss of availability can disrupt critical communication services. Pexip Infinity is widely used in enterprise and government sectors for video conferencing and collaboration, making this vulnerability impactful in environments where continuous availability is essential. No public exploits have been reported yet, but the vulnerability's characteristics suggest it could be weaponized quickly. The vendor has released version 37.1 to address this issue, though patch links were not provided in the source data. The CVSS v3.1 base score of 7.5 reflects the high impact on availability and the ease of exploitation.

For European organizations, the primary impact of CVE-2025-32096 is the disruption of video conferencing and unified communication services provided by Pexip Infinity. This can affect business continuity, remote work capabilities, and critical communication channels, especially in sectors like government, healthcare, finance, and large enterprises that rely heavily on these platforms. The denial of service could be leveraged by threat actors to cause operational downtime during sensitive periods or coordinated attacks. Given the remote and unauthenticated nature of the exploit, attackers could target exposed Pexip Infinity servers over the internet or internal networks if not properly segmented. This could lead to cascading effects such as missed meetings, delayed decision-making, and reduced productivity. Additionally, organizations may face reputational damage and potential regulatory scrutiny if service outages affect compliance with data protection or operational resilience requirements. The lack of confidentiality or integrity impact limits the risk of data breaches, but availability is critical for communication platforms, making this vulnerability a significant operational threat.

Organizations should prioritize upgrading Pexip Infinity to version 37.1 or later as soon as the patch becomes available to remediate the vulnerability. Until patches are applied, network-level mitigations should be implemented, such as restricting access to Pexip signaling ports to trusted IP addresses and using firewalls or intrusion prevention systems to detect and block malformed signaling messages. Monitoring network traffic for unusual signaling patterns can help identify attempted exploitation. Deploying rate limiting on signaling interfaces may reduce the risk of denial of service. Organizations should also review their exposure of Pexip Infinity servers to the internet and consider placing them behind VPNs or zero-trust network access solutions to limit attack surface. Regularly auditing and updating configurations to follow vendor security best practices will further reduce risk. Incident response plans should include procedures for quickly restoring service availability in case of an attack. Finally, maintaining up-to-date asset inventories and vulnerability management processes will ensure timely identification and remediation of affected systems.
