CVE-2025-64268 is a Missing Authorization vulnerability identified in Arraytics Timetics, a time management and scheduling software product, affecting versions up to and including 1.0.44. The flaw arises from incorrectly configured access control security levels, which fail to enforce proper authorization checks on certain functions or endpoints. This misconfiguration allows unauthenticated remote attackers to access sensitive information without requiring any user interaction or prior privileges. The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N), resulting in a high impact on confidentiality (C:H) but no impact on integrity (I:N) or availability (A:N). Although no known exploits have been reported in the wild, the ease of exploitation and the nature of the vulnerability make it a critical concern. The lack of patches at the time of disclosure necessitates immediate attention from organizations using Timetics. The vulnerability could lead to unauthorized data disclosure, potentially exposing sensitive employee or organizational information managed within Timetics. The issue was reserved on 2025-10-29 and published on 2025-12-18, with a CVSS v3.1 score of 7.5 indicating a high severity level. The absence of CWE identifiers suggests the vulnerability is specifically related to access control misconfiguration rather than a common coding error. Organizations should monitor vendor communications for patches and advisories.

For European organizations, the primary impact of CVE-2025-64268 is the unauthorized disclosure of sensitive data managed within the Timetics platform, which could include employee schedules, attendance records, and potentially confidential operational information. This breach of confidentiality can lead to privacy violations under GDPR, resulting in regulatory penalties and reputational damage. Since the vulnerability does not affect integrity or availability, operational disruption is less likely, but the exposure of sensitive data alone is significant. Organizations in sectors with strict data protection requirements, such as finance, healthcare, and government, face heightened risks. Additionally, attackers could leverage disclosed information for further targeted attacks or social engineering campaigns. The lack of authentication requirements and ease of exploitation mean that attackers can remotely access data without needing credentials, increasing the threat surface. The absence of known exploits currently provides a window for mitigation, but the vulnerability's characteristics suggest it could be weaponized quickly once exploit code is developed.

1. Monitor Arraytics vendor channels closely for official patches addressing CVE-2025-64268 and apply them immediately upon release. 2. Until patches are available, implement network-level access controls such as IP whitelisting or VPN requirements to restrict access to the Timetics application to trusted internal users only. 3. Conduct a thorough audit of Timetics user permissions and access logs to detect any unauthorized access attempts or anomalies. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting Timetics endpoints. 5. Segment the network to isolate the Timetics server from public-facing systems to reduce exposure. 6. Educate internal security teams about the vulnerability to ensure rapid incident response if exploitation is detected. 7. Review and enhance overall access control policies within Timetics to prevent similar misconfigurations in the future. 8. Consider implementing multi-factor authentication (MFA) for administrative access to Timetics, even though the vulnerability does not require authentication, to reduce risk from other attack vectors.
