CVE-2023-25997 is a Missing Authorization vulnerability classified under CWE-862 affecting the SolaPlugins product Sola Support Ticket, up to version 3.17. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform unauthorized actions that should be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The CVSS 3.1 base score is 6.5, indicating a medium severity level. The impact primarily affects integrity, allowing an attacker with some privileges to modify or manipulate data or operations within the ticketing system without proper authorization. Confidentiality and availability impacts are not present according to the CVSS vector. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because support ticket systems often contain sensitive customer information and internal operational data, and unauthorized modifications could lead to data corruption, misinformation, or disruption of support workflows. Since the vulnerability requires at least some level of privilege (PR:L), it is not exploitable by unauthenticated attackers but could be leveraged by malicious insiders or compromised user accounts to escalate their capabilities within the system.

For European organizations using Sola Support Ticket, this vulnerability poses a risk to the integrity of their customer support data and internal ticketing processes. Unauthorized changes to support tickets could result in incorrect handling of customer issues, potential data tampering, and loss of trust from customers. In regulated industries such as finance, healthcare, and telecommunications, where data integrity and audit trails are critical, exploitation could lead to compliance violations and reputational damage. Additionally, attackers might use this vulnerability to cover tracks or manipulate support workflows to delay incident response or escalate privileges further. The lack of confidentiality and availability impact reduces the risk of data leakage or denial of service, but the integrity compromise alone is significant for operational security. European organizations with integrated support systems relying on Sola Support Ticket should consider the risk of insider threats or compromised accounts exploiting this vulnerability.

1. Implement strict role-based access controls (RBAC) and regularly audit user permissions within the Sola Support Ticket system to ensure minimal privilege principles are enforced. 2. Monitor and log all privileged user activities and changes within the ticketing system to detect unauthorized modifications promptly. 3. Apply network segmentation and access restrictions to limit the exposure of the ticketing system to only trusted internal users and systems. 4. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of account compromise. 5. Stay vigilant for vendor updates or patches addressing this vulnerability and apply them promptly once available. 6. Conduct internal penetration testing and vulnerability assessments focusing on access control weaknesses in the ticketing system. 7. Educate support staff and administrators about the risks of privilege misuse and the importance of reporting suspicious activities. 8. If possible, implement additional application-layer authorization checks or compensating controls to mitigate the missing authorization issue until an official patch is released.
