CVE-2025-57897 identifies a reflected Cross-site Scripting (XSS) vulnerability in venusweb's Logtik product, versions up to 2.3. This vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious JavaScript code that executes in the context of a victim's browser. The attack vector is network-based (AV:N), requiring no privileges (PR:N), but user interaction (UI:R) is necessary, such as clicking a malicious link. The vulnerability has a scope change (S:C), meaning it can affect resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L), enabling attackers to steal session tokens, manipulate web content, or perform actions on behalf of users. Although no known exploits are currently reported in the wild, the high CVSS score (7.1) and the nature of reflected XSS make it a significant risk, especially for web-facing applications. The lack of available patches increases the urgency for organizations to implement interim mitigations. The vulnerability is particularly concerning for organizations relying on Logtik for critical web services, as exploitation could lead to data breaches or further compromise. The reflected XSS nature means attacks typically require social engineering to lure users into clicking crafted URLs. The vulnerability was reserved in August 2025 and published in December 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a substantial risk to web applications using venusweb Logtik, potentially exposing user sessions and sensitive data to attackers. The reflected XSS can facilitate credential theft, unauthorized actions, and distribution of malware, undermining user trust and regulatory compliance, especially under GDPR. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly vulnerable due to the sensitive nature of their data and services. The attack can lead to reputational damage, financial loss, and legal consequences. Since exploitation requires user interaction, phishing campaigns could be leveraged to maximize impact. The absence of patches increases exposure time, necessitating proactive defenses. The scope of affected systems includes all deployments of Logtik up to version 2.3, which may be integrated into various enterprise environments across Europe. The vulnerability could also be leveraged as a foothold for more advanced attacks, escalating the overall threat landscape.

1. Implement strict input validation and output encoding on all user-supplied data within Logtik web pages to neutralize malicious scripts. 2. Deploy Web Application Firewalls (WAFs) with rules tailored to detect and block reflected XSS payloads targeting Logtik endpoints. 3. Conduct regular security assessments and penetration testing focusing on XSS vulnerabilities in Logtik deployments. 4. Educate users and administrators about phishing risks and the importance of cautious interaction with unsolicited links. 5. Monitor web server and application logs for unusual request patterns indicative of XSS exploitation attempts. 6. Isolate Logtik instances within segmented network zones to limit lateral movement if compromised. 7. Engage with venusweb for timely patch releases and apply updates promptly once available. 8. Consider implementing Content Security Policy (CSP) headers to restrict script execution contexts. 9. Review and harden authentication and session management mechanisms to reduce impact if session tokens are compromised. 10. Maintain an incident response plan tailored to web application attacks including XSS scenarios.
