CVE-2025-12465 identifies a Blind SQL Injection vulnerability in OpenSolution QuickCMS, specifically version 6.8. The vulnerability stems from improper neutralization of special characters in input provided to the aFilesDelete function, which is accessible only by high-privileged users. Blind SQL Injection allows attackers to infer database information by sending crafted SQL queries and observing application behavior, even without direct error messages or output. The vulnerability does not require user interaction or authentication beyond high privilege, making it exploitable by insiders or compromised high-privilege accounts. The vendor was notified early but has not disclosed detailed vulnerability specifics or a patch, and other versions have not been tested, leaving uncertainty about the full scope. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required beyond high privilege, no user interaction, and high impact on confidentiality, integrity, and availability, with limited scope and no privileges beyond high privilege. This vulnerability could allow attackers to manipulate or exfiltrate sensitive data, modify database contents, or disrupt CMS operations. The lack of known exploits in the wild suggests limited current exploitation but also highlights the need for proactive defense. Given QuickCMS's use in various European organizations for content management, this vulnerability poses a significant risk if left unmitigated.

For European organizations, exploitation of this vulnerability could lead to unauthorized disclosure of sensitive data, including user information, configuration details, or proprietary content managed by QuickCMS. Attackers could alter or delete database records, potentially disrupting website functionality or causing data loss. Since the vulnerability requires high-privileged user input, insider threats or compromised administrative accounts pose the greatest risk. The impact extends to confidentiality, integrity, and availability of affected systems, potentially affecting public-facing websites, intranet portals, or document repositories. Organizations in sectors such as government, finance, healthcare, and media that rely on QuickCMS may face reputational damage, regulatory penalties under GDPR, and operational disruptions. The absence of patches increases exposure time, and the potential for automated exploitation tools to emerge elevates the threat level. Additionally, the vulnerability could be leveraged as a foothold for further lateral movement within networks, increasing overall risk.

1. Immediately audit and restrict access to high-privileged QuickCMS accounts to trusted personnel only, employing strong authentication and monitoring. 2. Implement strict input validation and sanitization on all user inputs, especially those related to file deletion or database commands, using parameterized queries or prepared statements to prevent SQL injection. 3. Conduct a thorough code review of the aFilesDelete function and related database interaction code to identify and remediate unsafe input handling. 4. Monitor database logs and application behavior for unusual query patterns indicative of blind SQL injection attempts. 5. Isolate QuickCMS instances on segmented network zones to limit lateral movement if compromised. 6. Engage with OpenSolution for official patches or updates and subscribe to vulnerability advisories for QuickCMS. 7. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block SQL injection payloads targeting QuickCMS. 8. Prepare incident response plans specific to CMS compromise scenarios, including data backup and restoration procedures. 9. Evaluate alternative CMS platforms if vendor support remains insufficient.
