CVE-2025-51053 is a Cross-site Scripting (XSS) vulnerability identified in the /api_vedo/ endpoint of Vedo Suite version 2024.17. This vulnerability allows remote attackers to inject arbitrary JavaScript or HTML code into the application, which can then be executed in the context of a victim's browser. The vulnerability is classified under CWE-79, which pertains to improper neutralization of input during web page generation. The attack vector is network-based (AV:N), requiring no privileges (PR:N) but does require user interaction (UI:R), such as clicking a malicious link or visiting a crafted webpage. The vulnerability impacts confidentiality and integrity, as attackers can steal session tokens, perform actions on behalf of the user, or manipulate displayed content. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the vulnerable component, potentially impacting other parts of the application or user data. The CVSS v3.1 base score is 6.1, categorized as medium severity. No known exploits are currently reported in the wild, and no patches have been linked yet. The lack of a patch suggests that organizations using Vedo Suite 2024.17 should consider this vulnerability a significant risk until remediation is available. The vulnerability's exploitation requires user interaction, which somewhat limits automated exploitation but does not eliminate the risk, especially in environments where users may be targeted via phishing or malicious links. Given the nature of XSS, the attack can be used for session hijacking, credential theft, or delivering further malware payloads via the victim's browser.

For European organizations using Vedo Suite 2024.17, this vulnerability poses a risk to the confidentiality and integrity of user sessions and data. Attackers exploiting this XSS flaw can hijack user sessions, steal sensitive information, or manipulate web content, potentially leading to unauthorized access or data leakage. This is particularly critical for organizations handling personal data under GDPR, as exploitation could result in data breaches with regulatory and reputational consequences. The vulnerability could also facilitate further attacks such as phishing or malware distribution within the organization. Since the vulnerability requires user interaction, the risk is heightened in environments where users may be targeted with social engineering attacks. The impact is more severe in sectors with high-value targets such as finance, healthcare, and government institutions, where compromised user sessions can lead to significant operational disruption or data exposure.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately audit and monitor all instances of Vedo Suite 2024.17 deployments to identify exposure to the /api_vedo/ endpoint. 2) Apply any available vendor patches or updates as soon as they are released. In the absence of patches, implement Web Application Firewall (WAF) rules specifically designed to detect and block malicious payloads targeting the /api_vedo/ endpoint, focusing on common XSS attack patterns. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the application. 4) Conduct user awareness training to reduce the risk of successful social engineering attacks that could trigger the vulnerability. 5) Review and sanitize all user inputs and outputs related to the /api_vedo/ endpoint, ensuring proper encoding and validation to prevent injection of malicious code. 6) Implement strict session management controls, including short session lifetimes and multi-factor authentication, to limit the impact of session hijacking. 7) Monitor logs for unusual activity or repeated attempts to exploit the vulnerability and respond promptly to incidents.
