CVE-2025-45878 is a cross-site scripting (XSS) vulnerability identified in the report manager function of Miliaris Amigdala version 2.2.6. This vulnerability enables an attacker to inject and execute arbitrary HTML or script code within the context of a user's browser session when interacting with the affected report manager component. The flaw arises due to insufficient input validation or output encoding of user-supplied data, allowing crafted payloads to be processed and rendered by the web application. Successful exploitation can lead to session hijacking, credential theft, unauthorized actions performed on behalf of the user, or delivery of malicious content such as malware. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and could be targeted by attackers once details become widely available. The lack of a CVSS score and absence of patch information suggest that remediation may still be pending or in early stages. The vulnerability affects Miliaris Amigdala v2.2.6, but no other version details are provided. Given that this is a client-side attack vector, exploitation requires the victim to access a maliciously crafted report or link within the application, implying some level of user interaction is necessary. The vulnerability does not appear to require authentication to exploit, but this cannot be definitively concluded from the available data. Overall, this XSS vulnerability poses a significant risk to the confidentiality and integrity of user sessions and data within affected deployments of Miliaris Amigdala.

For European organizations using Miliaris Amigdala v2.2.6, this XSS vulnerability could lead to serious security breaches including unauthorized access to sensitive information, session hijacking, and potential lateral movement within internal networks. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on this software for reporting functions may face data leakage or manipulation risks. The exploitation could undermine user trust and lead to regulatory non-compliance, especially under GDPR, due to exposure of personal data. Additionally, attackers could use the vulnerability as a foothold to deliver malware or conduct phishing campaigns targeting employees. The impact is heightened in environments where the application is accessible externally or integrated with other critical systems. Since no patches are currently available, organizations remain exposed until mitigations or updates are applied.

1. Implement strict input validation and output encoding on all user-supplied data within the report manager function to neutralize malicious payloads. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Restrict access to the report manager interface through network segmentation and strong authentication controls to limit exposure. 4. Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 5. Educate users about the risks of clicking on suspicious links or reports within the application. 6. Engage with the vendor for timely patch releases and apply updates as soon as they become available. 7. Consider deploying web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting this specific function. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities to proactively identify and remediate similar issues.
