CVE-2025-14729 is a code injection vulnerability identified in the CTCMS Content Management System, specifically affecting versions 2.1.0 through 2.1.2. The flaw exists in the Save function within the Backend App Configuration Module, located in the /ctcms/libs/Ct_App.php file. The vulnerability is triggered by manipulating the CT_App_Paytype argument, which is improperly sanitized or validated, allowing an attacker to inject malicious code. This code injection can be performed remotely without requiring authentication or user interaction, increasing the attack surface. The vulnerability can lead to arbitrary code execution on the server hosting the CMS, potentially compromising confidentiality, integrity, and availability of the affected system. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H but note the vector states PR:H which means privileges required are high, but the description says remote exploitation possible without authentication - this discrepancy suggests some privileges might be needed), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit code is publicly available, increasing the risk of exploitation, although no active exploitation in the wild has been reported to date. The vulnerability is significant for organizations relying on CTCMS for web content management, as successful exploitation could allow attackers to execute arbitrary commands, modify content, or disrupt services.

For European organizations using CTCMS versions up to 2.1.2, this vulnerability poses a moderate risk of remote code execution leading to unauthorized access, data manipulation, or service disruption. Compromise of CMS infrastructure can result in defacement, data breaches, or use of the server as a pivot point for further attacks within the network. Given the CMS’s role in managing web content, exploitation could impact customer trust, regulatory compliance (e.g., GDPR), and operational continuity. Organizations in sectors with high web presence such as e-commerce, media, and government are particularly vulnerable. The availability of public exploits increases the likelihood of opportunistic attacks, especially if patches or mitigations are not applied promptly. Although the CVSS score is medium, the potential for code execution elevates the threat beyond typical information disclosure vulnerabilities.

1. Upgrade CTCMS to a version later than 2.1.2 where this vulnerability is patched, or apply vendor-provided patches if available. 2. If immediate patching is not possible, implement web application firewall (WAF) rules to detect and block suspicious payloads targeting the CT_App_Paytype parameter. 3. Restrict access to the backend configuration module by IP whitelisting or VPN to limit exposure. 4. Conduct thorough input validation and sanitization on all user-supplied parameters, especially CT_App_Paytype, to prevent injection attacks. 5. Monitor web server and application logs for unusual activity or exploitation attempts related to this vulnerability. 6. Employ network segmentation to isolate CMS servers from critical internal systems to limit lateral movement in case of compromise. 7. Educate administrators on secure configuration and the importance of timely updates. 8. Regularly back up CMS data and configurations to enable recovery from potential attacks.
