Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Upgrade to Pexip Infinity version 38.0 or later as soon as the patch becomes available to address the improper input validation issue. 2. Until a patch is applied, implement network-level controls such as firewall rules or intrusion prevention systems to filter and rate-limit signalling traffic to and from Pexip servers, reducing the risk of malicious input triggering the assertion failure. 3. Monitor Pexip Infinity logs and system health metrics for signs of abnormal crashes or restarts that could indicate exploitation attempts. 4. Employ network segmentation to isolate Pexip infrastructure from less trusted networks, minimizing exposure. 5. Conduct regular vulnerability assessments and penetration testing focused on the signalling components to identify potential exploitation vectors. 6. Develop and test incident response plans specifically for denial of service scenarios affecting communication platforms to ensure rapid recovery. 7. Engage with Pexip support and subscribe to security advisories to receive timely updates and patches. 8. Educate IT and security teams about this vulnerability to increase awareness and readiness for detection and mitigation.

Description

CVE-2025-48704 is a high-severity vulnerability in Pexip Infinity versions 35.0 through 37.2 prior to 38.0, caused by improper input validation in the signalling component. This flaw allows an unauthenticated remote attacker to trigger a reachable assertion failure, causing the software to abort and resulting in a denial of service (DoS). The vulnerability does not impact confidentiality or integrity but severely affects availability. Exploitation requires no privileges or user interaction and can be performed remotely over the network. There are no known exploits in the wild yet, and no patches have been linked at the time of publication. European organizations using Pexip Infinity for video conferencing and collaboration services are at risk of service disruption. Countries with higher adoption of Pexip solutions and critical reliance on unified communications are most likely to be affected.

Impact

For European organizations, the primary impact of CVE-2025-48704 is the potential disruption of video conferencing and collaboration services provided by Pexip Infinity. This can lead to operational downtime, affecting business continuity, especially for sectors heavily reliant on remote communication such as finance, healthcare, government, and large enterprises. The denial of service could interrupt critical meetings, customer interactions, and internal communications, potentially causing financial losses and reputational damage. Since the vulnerability does not compromise data confidentiality or integrity, the risk of data breaches is low; however, the availability impact alone can be severe. Organizations with high dependency on Pexip's platform for daily operations will be more vulnerable to productivity losses. Additionally, the lack of authentication requirement for exploitation increases the threat surface, allowing external attackers to disrupt services without insider access. This could be leveraged in targeted attacks or as part of broader disruption campaigns, especially in geopolitical contexts where communication disruption is a strategic objective.

CWE-617Reachable Assertion (opens in a new tab)
Base weakness
The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
Implementation
Make sensitive open/close operation non reachable by directly user-controlled data (e.g. open/close resources)
Implementation · Input Validation
Perform input validation on user data.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
