CVE-2025-48492: CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') in GetSimpleCMS-CE GetSimpleCMS-CE
GetSimple CMS is a content management system. In versions starting from 3.3.16 to 3.3.21, an authenticated user with access to the Edit component can inject arbitrary PHP into a component file and execute it via a crafted query string, resulting in Remote Code Execution (RCE). This issue is set to be patched in version 3.3.22.
AI Analysis
Technical Summary
CVE-2025-48492 is a high-severity vulnerability affecting GetSimpleCMS-CE versions from 3.3.16 through 3.3.21. The vulnerability is classified under CWE-77, which involves improper neutralization of special elements used in a command, commonly known as command injection. Specifically, an authenticated user with access to the 'Edit component' functionality can inject arbitrary PHP code into a component file. This injected code can then be executed via a crafted query string, leading to Remote Code Execution (RCE) on the server hosting the CMS. The vulnerability arises because the application fails to properly sanitize or validate user input before incorporating it into PHP code execution contexts. This flaw allows an attacker with legitimate access to escalate privileges and execute arbitrary commands on the underlying system, potentially compromising the confidentiality, integrity, and availability of the web server and associated data. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based, making it exploitable remotely by authenticated users. The issue is scheduled to be fixed in version 3.3.22, but as of the publication date, no known exploits are reported in the wild. The CVSS 4.0 base score is 8.6, reflecting the high impact and ease of exploitation given the low attack complexity and no user interaction required beyond authentication. The vulnerability affects the core CMS product widely used for lightweight website management, making it a critical concern for organizations relying on this software for web presence and content management.
Potential Impact
For European organizations, the impact of CVE-2025-48492 can be significant, especially for small to medium enterprises, public sector bodies, and non-profits that use GetSimpleCMS-CE due to its simplicity and open-source nature. Successful exploitation could lead to full system compromise, allowing attackers to execute arbitrary code, deploy malware, deface websites, steal sensitive data, or pivot to internal networks. This could result in data breaches involving personal data protected under GDPR, leading to regulatory fines and reputational damage. Additionally, compromised CMS instances could be used as launchpads for further attacks, including ransomware or supply chain attacks targeting European digital infrastructure. The lack of known exploits in the wild currently provides a window for mitigation, but the high severity and ease of exploitation mean that attackers could develop exploits rapidly. Organizations with limited cybersecurity resources may be particularly vulnerable if they do not promptly update or implement compensating controls. The vulnerability also poses risks to the availability of web services, potentially disrupting business operations and public communications.
Mitigation Recommendations
1. Immediate upgrade to GetSimpleCMS-CE version 3.3.22 once it is released, as this version will contain the official patch addressing the vulnerability. 2. Until the patch is available, restrict access to the 'Edit component' functionality to only the most trusted and essential users, minimizing the number of authenticated users who can exploit the vulnerability. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious query strings that attempt to inject PHP code or unusual command patterns targeting component files. 4. Conduct regular code audits and input validation reviews on custom components or plugins to ensure no additional injection vectors exist. 5. Monitor web server logs and CMS activity logs for unusual behavior, such as unexpected query strings or file modifications, to detect potential exploitation attempts early. 6. Employ network segmentation to isolate CMS servers from critical internal networks, limiting lateral movement if a compromise occurs. 7. Backup CMS data and configuration regularly, ensuring that recovery is possible in case of compromise. 8. Educate authenticated users about the risks of phishing or credential compromise that could enable attackers to gain authenticated access.
