CVE-2025-30314 is a stored Cross-Site Scripting (XSS) vulnerability affecting Adobe Connect versions 12.8 and earlier. This vulnerability arises from insufficient input sanitization in certain form fields within the Adobe Connect web application, allowing an attacker to inject malicious JavaScript code that is persistently stored on the server. When a victim user accesses the affected page containing the malicious payload, the injected script executes in their browser context. This can lead to session hijacking, credential theft, unauthorized actions on behalf of the user, or the delivery of further malware. The vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The CVSS v3.1 base score is 6.1 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope changed (S:C), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 13, 2025, and reserved on March 20, 2025. Given Adobe Connect's role as a web conferencing and collaboration platform, exploitation could impact sensitive communications and data within affected organizations.

For European organizations, the impact of this vulnerability can be significant due to the widespread use of Adobe Connect for remote meetings, training, and collaboration, especially in sectors such as education, government, finance, and healthcare. Exploitation could allow attackers to steal session cookies or credentials, leading to unauthorized access to confidential meetings or documents. The integrity of communications could be compromised by injecting malicious content or redirecting users to phishing sites. Although availability is not directly impacted, the breach of confidentiality and integrity can result in reputational damage, regulatory penalties under GDPR for data breaches, and potential lateral movement within networks. Organizations relying heavily on Adobe Connect for critical communication may face operational disruptions if trust in the platform is undermined. The requirement for user interaction (visiting a maliciously crafted page) means social engineering or phishing campaigns could be used to trigger the exploit, increasing the risk in environments with less security awareness.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Monitor Adobe's official security advisories and apply patches or updates as soon as they become available, even though no patch link is currently provided. 2) Implement strict Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within Adobe Connect web pages. 3) Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting Adobe Connect endpoints. 4) Conduct user awareness training focused on recognizing phishing attempts that could lead to exploitation via malicious links. 5) Restrict access to Adobe Connect instances to trusted networks or VPNs where feasible, reducing exposure to external attackers. 6) Regularly audit and sanitize user-generated content and form inputs within Adobe Connect to detect and remove malicious scripts. 7) Use multi-factor authentication (MFA) for Adobe Connect accounts to limit the impact of credential theft. These measures, combined, reduce the attack surface and limit the potential damage from exploitation.
