CVE-2023-43183: n/a in n/a
Incorrect access control in Reprise License Management Software Reprise License Manager v15.1 allows read-only users to arbitrarily change the password of an admin and hijack their account.
AI Analysis
Technical Summary
CVE-2023-43183 is a high-severity vulnerability in the Reprise License Manager (RLM) software, version 15.1. The vulnerability stems from incorrect access control mechanisms that allow users with read-only privileges to escalate their permissions by arbitrarily changing the password of an administrative account. This flaw effectively enables a privilege escalation attack, where an attacker with limited access can hijack an admin account without requiring user interaction. The vulnerability has a CVSS v3.1 base score of 8.8, indicating a high impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L) and only low privileges (PR:L), but no user interaction (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects the same security scope. Successful exploitation allows full control over the license management system, potentially leading to unauthorized license manipulation, disruption of software licensing enforcement, and broader compromise of the infrastructure relying on RLM. Although no known exploits are currently reported in the wild, the severity and ease of exploitation make this a critical issue for organizations using RLM for license management.
Potential Impact
For European organizations, the impact of this vulnerability can be significant, especially for those relying on Reprise License Manager to enforce software licensing for critical applications. Unauthorized admin access can lead to license misuse, denial of service by disabling license enforcement, or even lateral movement within the network if the compromised admin credentials are reused elsewhere. This could disrupt business operations, cause compliance violations, and expose sensitive intellectual property. Additionally, organizations in regulated industries such as finance, healthcare, and manufacturing could face legal and financial repercussions due to compromised software license compliance and potential data breaches. The vulnerability also poses risks to software vendors using RLM to protect their products, potentially affecting their European customer base and damaging trust.
Mitigation Recommendations
To mitigate CVE-2023-43183, organizations should immediately verify if they are running Reprise License Manager version 15.1 or earlier versions that might be affected. Since no patch links are currently available, organizations should implement strict network segmentation to limit access to the RLM server, restricting it only to trusted administrators and essential systems. Monitoring and logging of all access attempts to the license manager should be enhanced to detect suspicious activities, especially password changes and privilege escalations. Organizations should enforce strong password policies and consider multi-factor authentication for admin accounts if supported by RLM. Additionally, reviewing and minimizing the number of users with read-only access can reduce the attack surface. Vendors and users should stay alert for official patches or updates from Reprise Software and apply them promptly once released. As a temporary workaround, disabling remote access to the license manager or using firewall rules to restrict access to known IP addresses can reduce exposure.
