CVE-2022-24896 is a security vulnerability identified in Enalean's Tuleap, an open-source software suite widely used for managing software development and collaboration projects. The vulnerability is classified under CWE-862, indicating a missing authorization control. Specifically, in Tuleap versions prior to 13.7.99.239, the system fails to properly verify user authorizations when rendering tracker report and chart widgets. This flaw allows malicious users to access sensitive metadata, such as the names of trackers and the fields used in reports, even if they do not have legitimate access rights to those trackers. While the vulnerability does not directly expose the content of the trackers or reports, the disclosure of tracker and field names can provide attackers with valuable reconnaissance information. This information could be leveraged to craft more targeted attacks or social engineering campaigns. The vulnerability does not require user interaction beyond accessing the affected widgets, and no authentication bypass is explicitly mentioned, suggesting that the attacker must have some level of access to the Tuleap instance but can escalate their visibility beyond their authorization scope. There are no known exploits in the wild, and no official patches are linked in the provided data, though the issue is resolved in versions 13.7.99.239 and later. The vulnerability primarily impacts the confidentiality of metadata within the Tuleap environment but does not appear to affect data integrity or availability directly.

For European organizations using Tuleap, particularly those involved in software development, project management, or collaborative engineering, this vulnerability poses a moderate risk. Disclosure of tracker and field names can reveal internal project structures, naming conventions, and potentially sensitive project components or priorities. This information leakage can aid attackers in mapping organizational workflows and identifying high-value targets for further exploitation, such as intellectual property theft or insider threat facilitation. Organizations in sectors with stringent data protection regulations, such as finance, healthcare, and critical infrastructure, may face compliance risks if sensitive project metadata is exposed. Although the vulnerability does not directly compromise data integrity or availability, the loss of confidentiality can undermine trust in project management systems and potentially expose organizations to targeted phishing or social engineering attacks. The impact is heightened in environments where Tuleap is integrated with other tools or where tracker names correlate closely with sensitive operational data.

Organizations should promptly upgrade Tuleap instances to version 13.7.99.239 or later, where the authorization checks have been properly implemented. In the absence of an immediate upgrade path, administrators should review and tighten access controls around tracker report and chart widgets, limiting visibility to only trusted users. Implementing strict role-based access control (RBAC) policies and auditing user permissions regularly can reduce the risk of unauthorized metadata exposure. Monitoring access logs for unusual activity related to tracker reports can help detect potential exploitation attempts. Additionally, organizations should educate users about the risks of information leakage and encourage cautious sharing of project metadata. Where feasible, consider isolating Tuleap instances or restricting access via network segmentation and VPNs to reduce exposure to untrusted users. Finally, maintain awareness of updates from Enalean and apply security patches as soon as they become available.
