CVE-2025-60447 is a stored Cross-Site Scripting (XSS) vulnerability identified in Emlog Pro version 2.5.19, specifically within the email template configuration module accessible at /admin/setting.php?action=mail. This vulnerability arises because the application fails to properly sanitize HTML input provided by administrators when configuring email templates. As a result, malicious JavaScript code can be persistently stored and executed in the context of the application whenever the affected templates are rendered or accessed. The flaw requires an attacker to have administrator-level privileges to inject the malicious payload, and exploitation also requires user interaction to trigger the script execution. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The CVSS v3.1 base score is 5.9, indicating a medium severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L. This means the attack can be launched remotely over the network with low attack complexity but requires high privileges and user interaction, and it affects confidentiality, integrity, and availability to a limited extent. No patches or known exploits are currently available, but the vulnerability poses a risk of session hijacking, defacement, or further exploitation through chained attacks. Given the persistent nature of stored XSS, the impact can extend beyond initial injection, affecting multiple users or system components that interact with the compromised templates.

For European organizations, the impact of CVE-2025-60447 could be significant in environments where Emlog Pro is used for managing email templates or related content. Exploitation could allow attackers with administrative access to inject malicious scripts that execute in the context of other administrators or users interacting with the email templates, potentially leading to session hijacking, credential theft, or unauthorized actions within the system. This could compromise sensitive organizational data, disrupt email communications, or facilitate lateral movement within internal networks. The vulnerability's requirement for administrator privileges limits the attack surface but also means that insider threats or compromised admin accounts could be leveraged. In sectors such as government, finance, healthcare, and critical infrastructure—where email systems are integral—such an exploit could undermine trust and operational continuity. Additionally, the persistent nature of stored XSS increases the risk of prolonged exposure and exploitation. Although no active exploits are known, the medium severity rating and potential for chained attacks warrant proactive mitigation.

To mitigate CVE-2025-60447, European organizations should implement several targeted measures beyond generic advice: 1) Restrict administrative access to the Emlog Pro email template configuration interface using strong authentication methods, such as multi-factor authentication (MFA) and IP whitelisting, to reduce the risk of unauthorized access. 2) Implement strict input validation and output encoding on all HTML inputs in the email template configuration, ensuring that any HTML or JavaScript code is properly sanitized or escaped before storage and rendering. 3) Regularly audit and monitor administrative activities and template changes for suspicious or unexpected modifications that could indicate exploitation attempts. 4) Isolate the email template management component within a secure network segment to limit potential lateral movement if compromised. 5) Maintain up-to-date backups of configuration data to enable rapid restoration in case of compromise. 6) Engage with Emlog Pro vendors or community to obtain patches or updates addressing this vulnerability as soon as they become available. 7) Educate administrators on the risks of injecting untrusted code and enforce strict policies on template content creation. These steps collectively reduce the likelihood of exploitation and limit the impact if an attack occurs.
