CVE-2025-25214 is a high-severity race condition vulnerability identified in the WWBN AVideo platform, specifically within the aVideoEncoder.json.php script's unzip functionality. This vulnerability arises due to improper synchronization when handling concurrent execution of shared resources, classified under CWE-362. In affected versions 14.4 and the development master commit 8a8954ff, an attacker can exploit this flaw by sending a series of specially crafted HTTP requests that manipulate the unzip process. The race condition can lead to arbitrary code execution on the server hosting the AVideo application. The vulnerability has a CVSS 3.1 base score of 8.8, indicating a high impact with network attack vector, low attack complexity, requiring low privileges but no user interaction, and affecting confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the potential for remote code execution makes this a critical concern for organizations using AVideo for video streaming or content management. The flaw allows attackers to execute malicious code remotely, potentially leading to full system compromise, data theft, or service disruption.

For European organizations deploying WWBN AVideo, this vulnerability poses significant risks. Given the nature of AVideo as a video hosting and streaming platform, exploitation could lead to unauthorized access to sensitive multimedia content, user data, and backend systems. This could result in intellectual property theft, privacy violations under GDPR, reputational damage, and operational downtime. The arbitrary code execution capability could allow attackers to pivot within the network, escalate privileges, or deploy ransomware. Organizations relying on AVideo for internal communications, educational content, or public-facing video services may experience service interruptions or data breaches. The impact is heightened in sectors such as media, education, and government agencies across Europe, where video content integrity and availability are critical.

To mitigate this vulnerability, European organizations should immediately upgrade to a patched version of WWBN AVideo once available. In the absence of an official patch, organizations should implement strict network-level access controls to restrict HTTP requests to trusted sources and monitor for unusual unzip-related activities. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious request patterns targeting the unzip functionality can reduce exploitation risk. Additionally, running AVideo in a sandboxed or containerized environment with minimal privileges limits the impact of potential code execution. Regularly auditing and monitoring logs for anomalies related to the aVideoEncoder.json.php endpoint is recommended. Organizations should also review and tighten file permissions and ensure that the unzip process does not run with elevated privileges. Finally, educating developers and administrators about race condition risks and secure coding practices can prevent similar vulnerabilities.
