AI Analysis

Impact

A flaw in refirio’s freo2 lets an attacker who holds the highest level of administrative privileges upload a file of any type, including executable binaries. The application then executes the uploaded file’s contents as an operating‑system command, granting the attacker full control over the server.

Affected Systems

The vulnerable product is freo2 from refirio. No specific version is listed, so all current or future releases are potentially affected until a vendor update is applied.

Risk and Exploitability

The CVSS score of 8.6 denotes a high‑severity issue. Because the attack requires local administrative access, the likelihood of an outsider exploiting it is low, but an insider or compromised administrator can abuse the flaw immediately. The EPSS score is not reported and the vulnerability is not in the CISA KEV catalog, indicating no known active exploitation at present.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest security patch for freo2 released by refirio that limits file uploads to safe types and prevents execution of the uploaded files.
  • If a patch is not yet available, disable the upload of executable files in the administrative interface or configure the application to reject files with MIME types associated with executables.
  • Configure the directory used for uploaded files so that the web server process cannot execute files from that location by adjusting file system permissions and disabling the appropriate executable flags.
