CVE-2024-0648 is a high severity unrestricted upload flaw in Yunyou CMS, scored CVSS 7.3. The record lists Yunyou CMS up to 2.2.6. The record names no fixed version. Read the checks below to find out whether you run an affected build.
What's affected
The record lists Yunyou CMS up to 2.2.6. The affected file is /app/index/controller/Common.php and the argument is templateFile.
The CVSS vector in the record is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, with a base score of 7.3 (High). KEV status: not listed in the record.
Fixed version: The record names no fixed version. Check the project for a newer release.
How to check if you're exposed
Find the installed version in the product admin area, its version file, or your deployment manifest, and compare it with the record. Review web server access logs for unexpected requests to the affected path, and check whether the admin or affected component is reachable from the internet.
What to do now
- Find every deployment of the affected product and its version.
- Apply the vendor fix if one exists. If the vendor has not responded, consider removing the product or placing it behind a web application firewall and an IP allow list.
- Block or monitor requests to the affected path, and review logs for earlier abuse.
- Restrict the admin area to a trusted network.
Why it matters
CWE-434 describes this class. Unrestricted upload of a dangerous file type means the application accepts a file without limiting its type or where it is stored. If an uploaded file can later be run by the server, the upload becomes a way to run code. Allow lists of extensions, content checks, and storing uploads outside the web root are the usual controls.
The record notes that an exploit has been disclosed publicly, which shortens the time between disclosure and scanning by others. The record does not say the flaw is exploited in the wild, and it is not in the CISA KEV catalog.
For a wider view, a free in-browser dependency scan and the Gold directory show where Yunyou CMS sits in your software, and reachability analysis helps separate code that can actually be hit from code that merely ships.
Quick check
Is CVE-2024-0648 exploited in the wild?
The record's KEV flag is false, and none of the pages I fetched said otherwise. That is not proof of safety, so still patch or restrict access.
What if no fix exists?
Restrict the affected path and the admin area to trusted networks, and consider replacing the product.
