CVE-2024-53554 is a Client-Side Template Injection (CSTI) vulnerability identified in the /project/new/scrum component of Taiga version 8.6.1, an open-source project management platform. CSTI vulnerabilities occur when user input is unsafely embedded into client-side templates, allowing attackers to inject and execute arbitrary code within the victim's browser context. In this case, remote attackers with limited privileges can inject malicious payloads into the new project details form, which is then processed by the client-side template engine. Successful exploitation requires the attacker to be authenticated and to trick a user into interacting with the malicious input, such as viewing or interacting with the crafted project details. The vulnerability can lead to arbitrary code execution, compromising confidentiality, integrity, and availability of the affected system and potentially the underlying server if the injected code escalates privileges or accesses sensitive resources. The CVSS 3.1 score of 8.0 reflects the high impact and relatively low complexity of exploitation, though user interaction and authentication are required. No official patches or fixes have been published at the time of disclosure, and no known exploits are currently active in the wild. The vulnerability is categorized under CWE-94 (Improper Control of Generation of Code), indicating unsafe handling of code generation or execution. Organizations using Taiga 8.6.1 should be aware of this vulnerability and take immediate steps to mitigate risk while awaiting an official patch.

The impact of CVE-2024-53554 is significant for organizations using Taiga 8.6.1, especially those relying on it for project management and collaboration. Exploitation can lead to arbitrary code execution within the client environment, potentially allowing attackers to steal sensitive information, manipulate project data, or disrupt service availability. Because the vulnerability requires authentication and user interaction, insider threats or social engineering attacks become more feasible. If exploited, attackers could escalate privileges or move laterally within the network, compromising broader organizational assets. The confidentiality of project details and user data is at risk, as is the integrity of project management workflows. Availability may also be affected if attackers deploy disruptive payloads. The absence of patches increases exposure time, and organizations without strict access controls or monitoring are at higher risk. This vulnerability could also undermine trust in the affected software, impacting business operations and compliance with data protection regulations.

To mitigate CVE-2024-53554, organizations should implement the following specific measures: 1) Restrict access to the Taiga instance and the /project/new/scrum component to trusted users only, minimizing the attack surface. 2) Enforce strong authentication and multi-factor authentication to reduce the risk of unauthorized access. 3) Educate users about social engineering risks and the importance of cautious interaction with project details. 4) Implement strict input validation and sanitization on all user-supplied data, especially within client-side templates, to prevent injection of malicious code. 5) Monitor logs and user activity for unusual behavior indicative of exploitation attempts. 6) Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting template injection. 7) Isolate the Taiga environment from critical infrastructure to limit potential lateral movement. 8) Regularly back up project data to enable recovery in case of compromise. 9) Stay informed about official patches or updates from Taiga and apply them promptly once available. 10) If feasible, temporarily disable or restrict the vulnerable /project/new/scrum functionality until a fix is released.
