Summary
Admidio Vulnerable to RCE via Arbitrary File Upload in Message Attachment
Impact
An attacker can exploit this flaw to upload a PHP web shell, which can be used to execute arbitrary commands on the server. This can lead to a complete compromise of the application server, allowing the attacker to:
- Execute arbitrary code or commands.
- Access, modify, or delete sensitive data.
- Install malicious software or scripts.
- Gain further access to internal networks.
- Disrupt services and applications hosted on the server.
The application accepts file uploads without adequately restricting the file type or content. Typical impact: remote code execution if the uploaded file can be served and executed on the server.
CVE-2024-38529 has a CVSS score of 9.0 (Critical). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (4.3.10); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
- Implement strict file extension verification to ensure that only allowed file types (e.g., images, documents) can be uploaded.
- Reject any file upload with disallowed or suspicious extensions such as .php, .phtml, .exe, etc.
Frequently Asked Questions
- What is CVE-2024-38529? CVE-2024-38529 is a critical-severity unrestricted upload of dangerous file types vulnerability in admidio/admidio (composer), affecting versions < 4.3.10. It is fixed in 4.3.10. The application accepts file uploads without adequately restricting the file type or content.
- How severe is CVE-2024-38529? CVE-2024-38529 has a CVSS score of 9.0 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of admidio/admidio are affected by CVE-2024-38529? admidio/admidio (composer) versions < 4.3.10 is affected.
- Is there a fix for CVE-2024-38529? Yes. CVE-2024-38529 is fixed in 4.3.10. Upgrade to this version or later.
- Is CVE-2024-38529 exploitable, and should I be worried? Whether CVE-2024-38529 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-38529 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2024-38529? Upgrade
admidio/admidioto 4.3.10 or later.
