Description
The Worry Proof Backup plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 0.2.4 via the backup upload functionality. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload a malicious ZIP archive with path traversal sequences to write arbitrary files anywhere on the server, including executable PHP files. This can lead to remote code execution.

AI Analysis

Impact

The Worry Proof Backup plugin for WordPress, versions up to 0.2.4, permits path traversal via the backup upload interface. An attacker who is authenticated with Subscriber or higher privileges can craft a ZIP archive containing directory traversal characters; when the plugin extracts the archive, it writes the files to arbitrary locations on the server. If a PHP file is uploaded, the attacker could execute it, resulting in remote code execution. The weakness corresponds to unvalidated file paths (CWE‑22).

Affected Systems

Affected systems include all installations of the BearThemes "Worry Proof Backup" WordPress plugin from the earliest release through version 0.2.4. Any instance that has the backup upload feature enabled and is accessible to Subscriber‑level or higher accounts is vulnerable. No later versions are affected.

Risk and Exploitability

The vulnerability has a CVSS score of 8.8, indicating high severity. The EPSS score is below 1 %, showing that the probability of exploitation is low at present, and it is not listed in the CISA KEV catalog. Attackers must first authenticate with a valid account that has Subscriber‑level or higher privileges, then upload a malicious ZIP to trigger the traversal. Once executed, the attacker could gain full control over the web server.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Worry Proof Backup to the latest version that removes the faulty upload handling (at least v0.2.5).
  • Restrict the backup upload feature to administrator accounts or disable it entirely until the vendor releases a fix.
  • Scan the site for unexpected files, especially PHP scripts, that may have been written by an attacker, and remove them.
