CVE-2025-15498 is a critical SQL injection vulnerability identified in Pro3W CMS version 1.2.0. The vulnerability stems from improper neutralization of special characters in user input fields, specifically the login form, which allows an unauthenticated attacker to inject malicious SQL commands. This injection flaw enables attackers to bypass authentication mechanisms and escalate privileges to administrative levels without any prior access or user interaction. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The CVSS 4.0 vector indicates the attack can be performed remotely over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high, with the vulnerability allowing significant control over the CMS backend. The vendor has not responded to inquiries, and no patches are available for versions prior to January 2026, when a fixed release is expected. Due to the lack of vendor response, the exact affected version range is unclear, but version 1.2.0 is confirmed vulnerable. No known exploits have been reported in the wild yet, but the critical nature of the flaw and ease of exploitation make it a high-risk threat for organizations using this CMS.

The impact of CVE-2025-15498 is severe for organizations running vulnerable versions of Pro3W CMS. Successful exploitation allows unauthenticated attackers to bypass login controls and gain full administrative privileges, effectively compromising the entire CMS environment. This can lead to unauthorized data access, data modification or deletion, website defacement, deployment of malicious content, and potential pivoting to internal networks. The integrity and availability of the CMS and hosted content are at high risk, potentially disrupting business operations and damaging organizational reputation. Since the vulnerability requires no authentication or user interaction, it can be exploited at scale by automated attacks, increasing the likelihood of widespread compromise. Organizations in sectors relying on Pro3W CMS for critical web infrastructure, such as government, finance, healthcare, and e-commerce, face heightened risks of data breaches, regulatory penalties, and operational downtime.

To mitigate CVE-2025-15498, organizations should prioritize upgrading to the fixed Pro3W CMS version released in January 2026 or later as soon as it becomes available. Until patches are applied, implement the following compensating controls: 1) Restrict external access to the CMS login interface using network-level controls such as IP whitelisting or VPN access. 2) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the login form. 3) Conduct thorough input validation and sanitization on all user inputs at the application layer, if possible through custom code or middleware. 4) Monitor CMS logs and network traffic for unusual login attempts or injection payloads. 5) Employ multi-factor authentication (MFA) on administrative accounts to reduce the impact of potential credential compromise. 6) Regularly back up CMS data and configurations to enable rapid recovery in case of compromise. 7) Engage in proactive threat hunting and vulnerability scanning focused on SQL injection vectors within the CMS environment. These measures will reduce exposure until official patches are deployed.
