CVE-2023-26002 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the 6Storage Rentals product by 6Storage, up to version 2.19.5. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker with some level of privileges (PR:L - privileges required: low) to exploit missing authorization checks. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The impact primarily affects the integrity of the system, as unauthorized users can perform actions or access resources they should not be permitted to, but it does not affect confidentiality or availability. The CVSS v3.1 base score is 4.3, indicating a medium severity level. There are no known exploits in the wild at this time, and no patches have been linked or published yet. The vulnerability could allow an attacker to bypass intended access controls, potentially modifying or manipulating data within the 6Storage Rentals application without proper authorization. Since the vulnerability requires low privileges, it could be exploited by users with limited access, increasing the risk of privilege escalation or unauthorized operations within the system. The lack of user interaction and network accessibility further increases the attack surface. The vulnerability is relevant to organizations using the 6Storage Rentals platform, which is a software solution for managing rental storage services.

For European organizations using 6Storage Rentals, this vulnerability poses a risk of unauthorized modification of rental data or operational parameters within the storage management system. This could lead to data integrity issues, incorrect billing, unauthorized access to rental units, or manipulation of customer records. While confidentiality and availability are not directly impacted, the integrity compromise could result in financial losses, reputational damage, and operational disruptions. Organizations in sectors such as logistics, warehousing, and property management that rely on 6Storage Rentals for critical business processes may experience workflow interruptions or customer trust erosion. The medium severity rating suggests that while the threat is not critical, it should be addressed promptly to prevent potential exploitation, especially since the vulnerability can be exploited remotely and without user interaction. The absence of known exploits in the wild provides a window for proactive mitigation before attackers develop weaponized exploits.

1. Implement strict access control policies within the 6Storage Rentals application, ensuring that authorization checks are correctly configured and enforced for all user roles and actions. 2. Conduct a thorough audit of user privileges and permissions to identify and remediate any excessive or inappropriate access rights, particularly for low-privilege users. 3. Monitor application logs for unusual or unauthorized activities that may indicate attempts to exploit missing authorization. 4. Engage with the vendor 6Storage to obtain official patches or updates addressing CVE-2023-26002 as soon as they become available. 5. Until patches are released, consider deploying network-level controls such as IP whitelisting, VPN access restrictions, or web application firewalls (WAF) to limit exposure of the 6Storage Rentals interface to trusted users only. 6. Educate system administrators and users about the risks of privilege misuse and the importance of reporting suspicious behavior. 7. Perform regular security assessments and penetration testing focused on access control mechanisms within the 6Storage Rentals environment to proactively identify and fix authorization gaps.
