CVE-2024-38530: Open eClass Platform allows Arbitrary File Upload in "modules/h5p/save.php"
Noroxi assessment
Priority: Monitor (action score 39/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.77% (FIRST EPSS); higher than 55.8% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: gunet openeclass 3.16.
Low priority for now. Upgrade to gunet openeclass 3.16 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
The Open eClass platform (formerly known as GUnet eClass) is a complete Course Management System. An arbitrary file upload vulnerability in the "save" functionality of the H5P module enables unauthenticated users to upload arbitrary files on the server's filesystem. This may lead in unrestricted RCE on the backend server, since the upload location is accessible from the internet. This vulnerability is fixed in 3.16.
