CVE-2025-9239 is a vulnerability identified in the elunez eladmin product, specifically affecting versions 2.0 through 2.7. The issue resides in the EncryptUtils function within the file eladmin-common/src/main/java/me/zhengjie/utils/EncryptUtils.java, which handles DES key encryption. The vulnerability stems from inadequate encryption strength due to the use of DES (Data Encryption Standard), a cryptographic algorithm considered weak by modern standards. The manipulation involves the argument STR_PARAM with the input 'Passw0rd', which suggests that the encryption implementation does not sufficiently protect sensitive data, potentially allowing attackers to compromise encrypted information. The attack can be initiated remotely without requiring authentication or user interaction, but it has a high complexity level, indicating that exploitation is difficult and likely requires advanced skills or specific conditions. The CVSS 4.0 score is 6.3 (medium severity), reflecting limited confidentiality impact and no integrity or availability impact. The vulnerability does not appear to have known exploits in the wild at the time of publication, and no patches or mitigations have been explicitly linked in the provided data. Overall, this vulnerability highlights the risks of relying on outdated encryption algorithms like DES in critical application components, which can undermine the security of sensitive data processed by eladmin.

For European organizations using elunez eladmin versions 2.0 to 2.7, this vulnerability poses a moderate risk primarily to the confidentiality of sensitive data encrypted using the affected DES-based mechanism. While the attack complexity is high and exploitation is difficult, successful exploitation could allow remote attackers to decrypt or weaken the protection of sensitive information such as passwords or configuration data. This could lead to unauthorized data disclosure or facilitate further attacks if attackers gain insights into system credentials or secrets. Given that eladmin is an administrative platform, compromised encryption could undermine trust in system integrity and confidentiality, potentially affecting compliance with European data protection regulations such as GDPR. However, the lack of impact on integrity and availability reduces the risk of system disruption or data tampering. The absence of known exploits in the wild lowers immediate urgency but does not eliminate the risk, especially for organizations with high-value targets or sensitive data processed by eladmin. Organizations should consider the potential reputational and regulatory consequences of data exposure resulting from this vulnerability.

European organizations should prioritize upgrading elunez eladmin to a version that replaces or removes the use of DES encryption in EncryptUtils, ideally moving to modern, secure encryption algorithms such as AES with strong key management. If an official patch is not yet available, organizations should implement compensating controls, including restricting network access to eladmin administrative interfaces to trusted IP ranges and enforcing strong authentication and monitoring to detect anomalous access attempts. Additionally, reviewing and rotating any credentials or sensitive data encrypted with the affected mechanism is advisable to limit exposure. Security teams should conduct thorough code audits and penetration testing focused on encryption handling within eladmin deployments. Logging and alerting should be enhanced to detect potential exploitation attempts. Finally, organizations should maintain close communication with the vendor for timely patch releases and apply updates promptly once available.
