CVE-2025-54047 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the QuanticaLabs Cost Calculator product. This vulnerability arises due to incorrectly configured access control security levels, which means that certain operations or data within the Cost Calculator can be accessed or manipulated by users who should not have the necessary permissions. The affected product versions are unspecified (noted as 'n/a' through 7.4), indicating that all versions up to 7.4 may be impacted. The vulnerability allows an attacker with at least some level of privileges (as indicated by the CVSS vector requiring PR:L, i.e., low privileges) to perform unauthorized actions that impact the integrity of the system, such as modifying cost calculation data or parameters. However, the vulnerability does not affect confidentiality or availability, and no user interaction is required to exploit it. The CVSS v3.1 base score is 4.3, categorizing it as a medium severity issue. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is remotely exploitable (AV:N) with low attack complexity (AC:L), and the scope remains unchanged (S:U). This suggests that an attacker can exploit the vulnerability over the network without complex conditions but must have some level of authenticated access (PR:L).

For European organizations using QuanticaLabs Cost Calculator, this vulnerability could lead to unauthorized modification of cost-related data or calculations, potentially resulting in financial misreporting, incorrect budgeting, or flawed decision-making based on manipulated cost data. While the vulnerability does not directly expose sensitive data (no confidentiality impact) or cause service disruption (no availability impact), the integrity compromise can undermine trust in financial systems and lead to compliance issues, especially under strict European data governance and financial regulations such as GDPR and SOX (for multinational companies). Attackers with low-level privileges, such as internal users or compromised accounts, could exploit this flaw to escalate their influence within the application, potentially affecting business operations. The absence of known exploits reduces immediate risk, but organizations should remain vigilant given the potential for future exploit development.

European organizations should implement the following specific mitigation measures: 1) Conduct a thorough access control audit on the QuanticaLabs Cost Calculator, verifying that authorization checks are correctly enforced for all sensitive operations and data access. 2) Restrict user privileges to the minimum necessary, ensuring that users with low privileges cannot perform unauthorized actions. 3) Monitor application logs for unusual access patterns or unauthorized attempts to modify cost data. 4) Engage with QuanticaLabs to obtain patches or updates addressing this vulnerability as soon as they become available. 5) If patches are not yet available, consider deploying compensating controls such as web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the Cost Calculator. 6) Educate internal users about the importance of safeguarding their credentials to prevent privilege escalation. 7) Integrate this vulnerability into the organization's vulnerability management program to track remediation progress and risk exposure.
