CVE-2025-56578 identifies a vulnerability in RTSPtoWeb version 2.4.3, a software solution that converts RTSP streams to web-accessible formats. The core issue arises from the absence of proper authentication mechanisms, classified under CWE-287 (Improper Authentication). This flaw allows a remote attacker, who must possess limited privileges (PR:L) and require user interaction (UI:R), to access sensitive information and execute arbitrary code on the affected system. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N) indicates network attack vector, low attack complexity, and no impact on integrity or availability but high impact on confidentiality. The vulnerability does not require physical access and can be exploited remotely over the network. Although no public exploits are currently known, the potential for sensitive data leakage and code execution poses a significant risk, especially in environments where RTSPtoWeb is used for streaming surveillance or media content. The lack of authentication means attackers could bypass access controls, leading to unauthorized data exposure and possible system compromise. The vulnerability was reserved in August 2025 and published in September 2025, with no patches currently available, highlighting the urgency for organizations to apply compensating controls.

For European organizations, the vulnerability could lead to unauthorized disclosure of sensitive streaming data, including potentially confidential video feeds or metadata, undermining privacy and compliance with regulations such as GDPR. The ability to execute arbitrary code elevates the risk to system integrity, potentially allowing attackers to deploy malware, pivot within networks, or disrupt services indirectly. Organizations in sectors like critical infrastructure, public safety, transportation, and media that rely on RTSPtoWeb for real-time video streaming are particularly vulnerable. The exposure could result in reputational damage, regulatory penalties, and operational disruptions. Since the vulnerability requires some privilege and user interaction, insider threats or social engineering could facilitate exploitation. The absence of known exploits currently provides a window for proactive defense, but the medium severity score suggests that the threat should not be underestimated.

1. Implement strong authentication controls around RTSPtoWeb interfaces, including multi-factor authentication where possible. 2. Restrict network access to RTSPtoWeb services using firewalls and network segmentation to limit exposure to trusted hosts only. 3. Monitor logs and network traffic for unusual access patterns or failed authentication attempts that could indicate exploitation attempts. 4. Employ application-layer gateways or reverse proxies to enforce additional authentication and input validation. 5. Educate users and administrators about social engineering risks and the importance of not interacting with suspicious prompts or links. 6. Regularly audit and update RTSPtoWeb deployments, applying patches promptly once available. 7. Consider isolating RTSPtoWeb servers in dedicated environments with minimal privileges to reduce the impact of potential compromise. 8. Use endpoint detection and response (EDR) tools to detect anomalous code execution behaviors related to this vulnerability.
