CVE-2024-31454

The absence of restrictions on the endpoint, which is designed for uploading files, allows an attacker who received the id of a file distribution to change the files that are in this distribution.

Details

Vulnerable endpoint: PATCH /files/{{id}}

PoC

1. Create a file distribution.

2. Go to the link address for downloading files and download the file (in this case, the attacker receives the file id from the download request).

3. Send a PATCH /files/{{id}} request with arbitrary content in the request body.

Thus, the file with the specified id will be changed. What the attacker specifies in the body of the request will be added to the end of the original content. In the future, users will download the modified file.

The vulnerability allows an attacker to influence those users who come to the file distribution after him and slip the victim files with a malicious or phishing signature.

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-2024-31454 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no 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 (2.2.0); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2024-31454? CVE-2024-31454 is a medium-severity unrestricted upload of dangerous file types vulnerability in psitransfer (npm), affecting versions < 2.2.0. It is fixed in 2.2.0. The application accepts file uploads without adequately restricting the file type or content.
2. How severe is CVE-2024-31454? CVE-2024-31454 has a CVSS score of 6.5 (Medium). 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.
3. Which versions of psitransfer are affected by CVE-2024-31454? psitransfer (npm) versions < 2.2.0 is affected.
4. Is there a fix for CVE-2024-31454? Yes. CVE-2024-31454 is fixed in 2.2.0. Upgrade to this version or later.
5. Is CVE-2024-31454 exploitable, and should I be worried? Whether CVE-2024-31454 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.

6. What actually determines whether CVE-2024-31454 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.
7. How do I fix CVE-2024-31454? Upgrade psitransfer to 2.2.0 or later.
