CVE-2025-49248 is a security vulnerability classified under CWE-862, which pertains to Missing Authorization. This vulnerability affects the 'Team Showcase' product developed by cmoreira. The core issue arises from incorrectly configured access control security levels, allowing an attacker with some level of privileges (PR:L - low privileges) to perform actions or access resources beyond their authorized scope. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The CVSS v3.1 base score is 4.3, indicating a low severity level. The impact is limited to integrity (I:L) with no confidentiality (C:N) or availability (A:N) impact. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component and does not extend to other components or systems. No specific affected versions are listed, and no patches or known exploits are currently available. The vulnerability likely allows unauthorized modification or manipulation of data or configurations within the Team Showcase application, potentially leading to unauthorized changes or defacement but not data leakage or denial of service. Since the vulnerability requires some level of privileges, it is not exploitable by unauthenticated attackers, which limits the attack surface. Overall, this vulnerability represents a moderate risk primarily to the integrity of the affected application environment.

For European organizations using the Team Showcase product by cmoreira, this vulnerability could lead to unauthorized modifications within the application, potentially undermining the integrity of showcased content or configurations. While it does not compromise confidentiality or availability, unauthorized changes could damage organizational reputation, mislead users, or disrupt business processes relying on accurate display of information. The requirement for low-level privileges means that internal threat actors or compromised accounts could exploit this vulnerability, emphasizing the need for strict internal access controls. Given the lack of known exploits in the wild and the low CVSS score, the immediate risk is limited; however, organizations should remain vigilant as attackers may develop exploits over time. The impact is more pronounced for organizations that rely heavily on Team Showcase for public-facing or critical internal presentations, especially in sectors where data integrity and trustworthiness are paramount, such as finance, healthcare, and government institutions.

1. Conduct a thorough review of access control configurations within the Team Showcase application to ensure that authorization checks are correctly implemented and enforced at all levels. 2. Implement the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions to perform their tasks. 3. Monitor and audit user activities within the application to detect any unauthorized access or modifications promptly. 4. Engage with the vendor or developer (cmoreira) to obtain patches or updates addressing this vulnerability as they become available. 5. If patches are not yet available, consider applying compensating controls such as network segmentation, restricting access to the application to trusted users, and employing web application firewalls (WAFs) to detect and block suspicious requests. 6. Educate internal users about the risks of privilege misuse and enforce strong authentication mechanisms to reduce the risk of account compromise. 7. Regularly update and review security policies related to application access and change management to prevent exploitation of missing authorization issues.
