CVE-2025-10014 is a security vulnerability identified in the elunez eladmin product, affecting versions 2.0 through 2.7. The flaw resides in the updateUserEmail function within the /api/users/updateEmail/ endpoint, specifically in the Email Address Handler component. The vulnerability arises due to improper authorization checks when manipulating the 'id' or 'email' arguments. This improper authorization could potentially allow an attacker to update the email address of a user account without proper permissions. However, exploitation complexity is high because the attacker must possess the RSA-encrypted password of the targeted user account, which acts as a significant barrier to unauthorized access. The attack can be performed remotely, but no user interaction is required, and the attacker only needs low privileges (PR:L) to attempt exploitation. The CVSS 4.0 base score is 2.3, indicating a low severity level, primarily because the impact on confidentiality and integrity is limited (partial impact on integrity), and the exploitability is difficult due to the need for the encrypted password. No known exploits are currently observed in the wild, and no patches or mitigations have been officially published at the time of this report. The vulnerability does not affect availability and does not require user interaction, but the scope is limited to the affected versions of eladmin. This vulnerability could be leveraged to alter user email addresses, potentially leading to account takeover scenarios if combined with other weaknesses or credential leaks.

For European organizations using elunez eladmin versions 2.0 to 2.7, this vulnerability could pose a risk to user account integrity by allowing unauthorized modification of user email addresses. This could facilitate social engineering, phishing, or account recovery attacks if attackers manage to obtain the RSA-encrypted password of targeted users. While the direct impact is low, the vulnerability could be a stepping stone in multi-stage attacks, especially in environments where eladmin is used for administrative or user management purposes. Organizations handling sensitive personal data or critical user accounts might face increased risk of identity-related fraud or unauthorized access. However, the high complexity and requirement of possessing encrypted credentials reduce the likelihood of widespread exploitation. The absence of known exploits in the wild further lowers immediate risk, but organizations should remain vigilant. The impact on confidentiality is minimal, but integrity could be partially compromised, affecting trust in user account data. Availability is unaffected.

Given the lack of an official patch, European organizations should implement compensating controls to mitigate this vulnerability. First, restrict access to the /api/users/updateEmail/ endpoint using network-level controls such as IP whitelisting or VPN-only access to limit exposure. Enforce strong encryption and secure storage of RSA-encrypted passwords to prevent credential leakage. Implement multi-factor authentication (MFA) to reduce the risk of unauthorized account access even if email addresses are manipulated. Conduct regular audits of user email changes and monitor logs for suspicious activity related to email updates. If possible, upgrade to a later, patched version of eladmin once available. Additionally, consider application-layer authorization enhancements to ensure that only authorized users can update their own email addresses. Educate users and administrators about phishing and social engineering risks that could arise from email manipulation. Finally, isolate eladmin instances in segmented network zones to reduce the blast radius in case of compromise.
