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 handler, specifically a reachable assertion (CWE-617) that can be triggered remotely by an attacker sending a crafted signalling message. This assertion failure causes the software to abort unexpectedly, leading to a denial of service condition. The vulnerability affects all versions prior to 37.0 and does not require any authentication or user interaction, making it remotely exploitable over the network with low attack complexity. The CVSS v3.1 base score is 7.5, reflecting high severity due to the complete loss of availability without impact on confidentiality or integrity. Although no public exploits have been observed, the nature of the flaw suggests that attackers could disrupt critical communication services by repeatedly triggering the assertion failure. The signalling component is integral to session establishment and management, so disruption can halt conferencing capabilities. The lack of patches at the time of publication indicates that organizations must rely on interim mitigations until vendor updates are released. Given Pexip Infinity’s deployment in enterprise and government environments, this vulnerability poses a significant operational risk.

For European organizations, the primary impact is the disruption of video conferencing and unified communication services, which are critical for remote work, collaboration, and operational continuity. Denial of service attacks exploiting this vulnerability could interrupt meetings, delay decision-making, and degrade productivity. Sectors such as government, healthcare, finance, and large enterprises that depend heavily on Pexip Infinity for secure communications are particularly vulnerable. Additionally, critical infrastructure entities using this platform could face operational risks if communications are disrupted. The impact on availability could also affect incident response and crisis management capabilities. While confidentiality and integrity are not directly compromised, the loss of availability can have cascading effects on business operations and service delivery. The remote and unauthenticated nature of the exploit increases the likelihood of opportunistic attacks, especially in the context of geopolitical tensions or targeted cyber campaigns in Europe.

1. Immediately monitor network traffic for unusual or malformed signalling messages targeting Pexip Infinity systems. 2. Implement network-level filtering and rate limiting on signalling ports to reduce exposure to crafted messages. 3. Isolate Pexip Infinity servers within segmented network zones with strict access controls to limit attack surface. 4. Engage with Pexip support to obtain patches or hotfixes as soon as they become available and apply them promptly. 5. Conduct regular vulnerability scans and penetration tests focusing on signalling protocol robustness. 6. Develop and test incident response plans that include recovery procedures for denial of service conditions affecting communication platforms. 7. Educate IT and security teams about this specific vulnerability to improve detection and response capabilities. 8. Consider deploying Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block malformed signalling traffic. 9. Maintain up-to-date asset inventories to quickly identify and remediate affected Pexip Infinity instances.
