CVE-2025-62020 is a cross-site scripting (XSS) vulnerability identified in Infomaniak Network's VOD Infomaniak product, affecting versions up to and including 1.5.11. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows attackers to inject malicious JavaScript code into the application. This type of vulnerability can be exploited by an attacker to execute arbitrary scripts in the context of the victim's browser session, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, defacement of web content, or redirection to malicious websites. The vulnerability does not require authentication, increasing the risk of exploitation by remote attackers. Although no public exploits are currently known, the presence of this vulnerability in a widely used video-on-demand platform necessitates urgent attention. The lack of a CVSS score means severity must be assessed based on impact and exploitability factors. The vulnerability affects the confidentiality and integrity of user data and the availability of the service could be indirectly impacted through exploitation. The scope is limited to users interacting with the vulnerable web interface, but the potential for widespread impact exists if exploited at scale. The vulnerability was published on October 22, 2025, and no patches or mitigations have been officially released yet, emphasizing the need for immediate defensive measures.

For European organizations using VOD Infomaniak, this XSS vulnerability poses a significant risk to the confidentiality and integrity of user data. Attackers could exploit the flaw to steal session cookies, enabling unauthorized access to user accounts and potentially sensitive content. This could lead to data breaches, reputational damage, and regulatory non-compliance under GDPR due to the exposure of personal data. The integrity of the platform could be compromised by injecting malicious scripts that alter content or redirect users to phishing sites, undermining user trust. Availability might be indirectly affected if attackers use the vulnerability to conduct further attacks such as distributed denial-of-service (DDoS) or to spread malware. Since the vulnerability does not require authentication, it can be exploited by any remote attacker, increasing the threat surface. European organizations relying on VOD Infomaniak for streaming services or internal communications could face operational disruptions and increased incident response costs. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors often weaponize disclosed vulnerabilities rapidly.

European organizations should immediately audit their use of VOD Infomaniak and identify affected versions (<=1.5.11). Until an official patch is released, implement strict input validation and output encoding on all user-supplied data to prevent script injection. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. Conduct regular security testing, including automated scanning and manual penetration testing focused on input handling. Monitor web application logs and user activity for signs of exploitation attempts or anomalous behavior. Educate users about the risks of clicking on suspicious links or executing unknown scripts. If possible, isolate the VOD platform within a segmented network environment to limit lateral movement in case of compromise. Engage with Infomaniak support to obtain updates on patches or official mitigation guidance. Finally, prepare incident response plans specific to web application attacks to ensure rapid containment and recovery.
