CVE-2025-62098 is a missing authorization vulnerability classified under CWE-862 affecting Totalsoft's Portfolio Gallery product up to version 1.4.8. The flaw arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to perform unauthorized actions that impact the integrity and availability of the system. The vulnerability is remotely exploitable over the network (AV:N) without requiring user interaction (UI:N), which increases its risk profile. However, some level of privilege is required, which limits exploitation to authenticated users with certain access rights. The vulnerability does not compromise confidentiality but can lead to unauthorized modifications or disruptions of the Portfolio Gallery service. No patches or known exploits have been reported yet, but the vulnerability's presence indicates a potential for misuse in environments where access control is not properly enforced. The CVSS 3.1 base score of 5.4 reflects a medium severity rating, balancing ease of exploitation with limited impact scope. Organizations using Portfolio Gallery should audit their access control configurations and apply compensating controls to prevent unauthorized operations.

For European organizations, the vulnerability poses a risk primarily to the integrity and availability of the Portfolio Gallery application, which may be used for managing digital assets or portfolios. Unauthorized modifications could lead to data tampering, service disruptions, or operational delays, impacting business continuity and trustworthiness of managed content. Since confidentiality is not affected, data leakage risks are minimal. However, the requirement for some privilege means insider threats or compromised accounts could exploit this flaw. Industries relying on Portfolio Gallery for critical asset management, such as finance, media, or government agencies, could face operational and reputational damage. The lack of known exploits reduces immediate risk, but the vulnerability could be leveraged in targeted attacks or combined with other vulnerabilities for greater impact. European organizations must consider this threat in their risk assessments and incident response planning.

To mitigate CVE-2025-62098, organizations should first conduct a thorough review of Portfolio Gallery's access control configurations, ensuring that authorization checks are correctly implemented and enforced for all sensitive operations. Limit user privileges strictly to the minimum necessary, applying the principle of least privilege. Implement robust monitoring and logging of privileged user activities to detect anomalous behavior that could indicate exploitation attempts. Where possible, segment the Portfolio Gallery environment to reduce the blast radius of potential attacks. Since no official patches are currently available, consider deploying Web Application Firewalls (WAFs) with custom rules to block unauthorized access patterns. Engage with Totalsoft support channels to obtain updates or patches as they become available. Additionally, conduct regular security training for administrators and users to raise awareness about access control best practices and insider threat risks.
