WordPress WineShop theme <= 3.17 - Local File Inclusion vulnerability

Vulnerability

The WineShop WordPress theme versions 3.17 and earlier are vulnerable to an unauthenticated Local File Inclusion (LFI) bug. The theme fails to properly sanitize user-supplied input, allowing an attacker to include arbitrary local files via crafted HTTP requests. No authentication or special privileges are required to trigger the vulnerability. [1]

Exploitation

An attacker can exploit this by sending a specially crafted request containing a path traversal sequence (e.g., ../../) to the vulnerable parameter. As the vulnerability is unauthenticated, the attacker only needs network access to the target website. No user interaction or prior access is needed. [1]

Impact

Successful exploitation allows the attacker to read arbitrary files from the server filesystem, including sensitive configuration files that may contain database credentials, API keys, or other secrets. This information disclosure could lead to complete database compromise, privilege escalation, or further attacks on the site and its users. [1]

Mitigation

Update the WineShop theme to a version higher than 3.17 as soon as possible. The vendor has released a fix in a newer version. If an immediate update is not feasible, consider temporarily deactivating the theme or implementing a web application firewall rule to block path traversal patterns. The vulnerability is expected to be actively exploited in mass campaigns. [1]
