CVE-2025-45880 is a cross-site scripting (XSS) vulnerability identified in the data resource management function of Miliaris Amigdala version 2.2.6. This vulnerability allows an attacker to inject and execute arbitrary HTML or JavaScript code within the context of a user's browser session. The attack vector involves crafting a malicious payload that, when processed by the vulnerable function, is rendered without proper sanitization or encoding, enabling script execution. This type of vulnerability can lead to session hijacking, credential theft, unauthorized actions on behalf of the user, or distribution of malware through the compromised web interface. The vulnerability affects the specific version 2.2.6 of Miliaris Amigdala, a software product whose market penetration and usage details are not explicitly provided. No patches or fixes have been linked or published at the time of this report, and no known exploits are currently observed in the wild. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity, but the nature of XSS vulnerabilities generally poses significant risks to confidentiality and integrity of user sessions and data. The vulnerability was reserved in April 2025 and published in June 2025, indicating recent discovery and disclosure.

For European organizations using Miliaris Amigdala v2.2.6, this XSS vulnerability could lead to several adverse impacts. Attackers exploiting this flaw could execute malicious scripts in users' browsers, potentially stealing session cookies, login credentials, or other sensitive information. This could result in unauthorized access to internal systems or data breaches. Additionally, attackers might perform actions on behalf of legitimate users, leading to data manipulation or unauthorized transactions. The vulnerability could also be leveraged to distribute malware or launch phishing attacks targeting employees or partners. Given the web-based nature of the vulnerability, any organization relying on this software for critical data resource management could face operational disruptions, reputational damage, and regulatory compliance issues under GDPR if personal data is compromised. The lack of known exploits currently reduces immediate risk but does not eliminate the potential for targeted attacks, especially as threat actors often develop exploits following public disclosure. The impact on availability is generally limited for XSS but could be indirect if exploitation leads to broader compromise or service disruption.

To mitigate the risk posed by CVE-2025-45880, European organizations should implement the following specific measures: 1) Conduct an immediate audit to identify all instances of Miliaris Amigdala v2.2.6 in use across the organization. 2) Apply strict input validation and output encoding on all user-supplied data within the data resource management functions, even if official patches are not yet available. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the application. 4) Implement web application firewalls (WAFs) with rules designed to detect and block typical XSS payloads targeting the affected endpoints. 5) Educate users about the risks of unsolicited links or payloads and encourage cautious behavior when interacting with the application. 6) Monitor application logs and network traffic for unusual activities indicative of attempted exploitation. 7) Engage with the vendor or software maintainers to obtain or request timely security patches or updates. 8) Consider isolating or restricting access to the vulnerable application components until a fix is deployed. These steps go beyond generic advice by focusing on compensating controls and proactive detection tailored to the specific vulnerability context.
