CVE-2025-9240 is a medium-severity information disclosure vulnerability affecting elunez eladmin versions 2.0 through 2.7. The flaw resides in an unspecified functionality of the /auth/info endpoint, which can be manipulated remotely without authentication or user interaction. Exploiting this vulnerability allows an attacker to access sensitive information that should otherwise be protected. The CVSS 4.0 vector indicates the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and limited impact on confidentiality (VC:L) with no impact on integrity or availability. Although the exact nature of the disclosed information is not detailed, such leaks can include user data, configuration details, or authentication metadata that could facilitate further attacks or reconnaissance. The vulnerability is exploitable remotely, increasing its risk profile, and a public exploit has been released, raising the likelihood of active exploitation despite no confirmed reports of exploitation in the wild yet. The lack of patches at the time of publication suggests that affected organizations must rely on mitigation strategies until official fixes are available.

For European organizations using elunez eladmin, this vulnerability poses a risk of unauthorized disclosure of sensitive information, potentially including user credentials, system configurations, or internal metadata. Such information leakage can aid attackers in crafting targeted attacks, escalating privileges, or bypassing security controls. Sectors with high regulatory requirements such as finance, healthcare, and government could face compliance violations under GDPR if personal data is exposed. Additionally, organizations relying on eladmin for administrative or identity management functions may experience increased risk of lateral movement or further compromise. The remote exploitation capability means attackers can attempt to exploit this vulnerability from outside the network perimeter, increasing exposure. While the impact on integrity and availability is not indicated, the confidentiality breach alone can have significant operational and reputational consequences.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Restrict access to the /auth/info endpoint via network-level controls such as IP whitelisting or VPN-only access to limit exposure to trusted users. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting /auth/info, especially those attempting parameter manipulation. 3) Conduct thorough logging and monitoring of access to the /auth/info endpoint to detect anomalous or repeated access attempts indicative of exploitation attempts. 4) Review and harden eladmin configuration to minimize information exposure, including disabling or restricting debug or verbose error messages. 5) Isolate eladmin instances in segmented network zones to reduce the blast radius if compromised. 6) Prepare for rapid patch deployment once an official fix is released by maintaining an up-to-date inventory of affected versions. 7) Educate administrators about the vulnerability and encourage prompt reporting of suspicious activity related to eladmin. These targeted actions go beyond generic advice by focusing on the specific vulnerable endpoint and the nature of the information disclosure.
