CVE-2025-45610 is a high-severity vulnerability identified in the PassJava-Platform version 3.0.0, specifically within the /scheduleLog/info/1 component. The vulnerability stems from incorrect access control, categorized under CWE-284 (Improper Access Control). This flaw allows unauthenticated remote attackers to access sensitive information by sending a crafted payload to the vulnerable endpoint. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the attack can be executed over the network without any privileges or user interaction, and it results in a complete compromise of confidentiality, while integrity and availability remain unaffected. The vulnerability does not require authentication, making it easier to exploit. Although no known exploits are currently reported in the wild, the high CVSS score of 7.5 indicates a significant risk. The lack of vendor or product details beyond the platform name and version limits the ability to pinpoint exact affected modules or configurations. The vulnerability's presence in a platform named PassJava-Platform suggests it may be used in enterprise or organizational environments, potentially handling scheduling or logging functionalities, which could contain sensitive operational or user data. The absence of a patch link implies that a fix may not yet be publicly available, increasing the urgency for organizations to implement interim mitigations.

For European organizations, this vulnerability poses a substantial risk to the confidentiality of sensitive information managed by the PassJava-Platform. Unauthorized disclosure could lead to exposure of personal data, intellectual property, or operational details, potentially violating GDPR and other data protection regulations. The ease of exploitation without authentication or user interaction increases the likelihood of automated scanning and exploitation attempts, which could lead to data breaches and reputational damage. Organizations relying on this platform for critical scheduling or logging functions may face operational risks if attackers leverage the exposed information for further attacks or social engineering. The breach of confidentiality could also impact trust with customers and partners, and trigger regulatory scrutiny and fines under European data protection laws.

Given the absence of an official patch, European organizations should immediately implement network-level access controls to restrict access to the /scheduleLog/info/1 endpoint, limiting it to trusted internal IP addresses or VPN connections. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting this endpoint can reduce exposure. Conduct thorough audits of access logs to identify any anomalous or unauthorized access attempts. Organizations should also review and harden access control policies within the PassJava-Platform configuration, if possible, to enforce strict authentication and authorization checks. Monitoring for updates from the vendor or security advisories is critical to apply patches promptly once available. Additionally, organizations should prepare incident response plans to address potential data breaches resulting from exploitation of this vulnerability.
