Between late 2023 and early 2024, adversaries incorporated the Nicepage 4.5.4 exploit into automated scanning tools. Reports from Wordfence and Sucuri indicated:
By manipulating the template parameter, an attacker could force the plugin to read and execute arbitrary files on the server via PHP’s include() function.
Example Malformed Request:
POST /wp-admin/admin-ajax.php HTTP/1.1 Host: target-site.com Content-Type: application/x-www-form-urlencoded
action=nicepage_activate_theme&template=../../../../wp-config.php%00
This request would retrieve the wp-config.php file, exposing database credentials.
The core issue in Nicepage 4.5.4 lies within its AJAX action handlers and improper sanitization of user-supplied input inside the nicepage_activate_theme function. Specifically, the vulnerability exists in the class Nicepage_Theme_Manager.
The discussion of specific exploits should always be approached with caution and a strong adherence to ethical guidelines. If you're dealing with a known vulnerability like the one mentioned, prioritize reporting it to the vendor, updating affected systems, and engaging with the cybersecurity community in a responsible manner.
While there is no widely documented or CVE-assigned "exploit" specifically for Nicepage version 4.5.4, security researchers and users have highlighted specific vulnerabilities in older versions of the Nicepage CMS Editor Plugin and the environments in which it often operates, such as WordPress. Understanding the Risks in Nicepage 4.5.4
Vulnerabilities associated with web builders like Nicepage often stem from how the plugin interacts with the CMS backend or handles user input.
Sensitive Path Exposure: Older versions of the Nicepage plugin have been flagged by security tools for exposing sensitive paths like /wp-admin in the source code. This visibility can entice attackers to perform brute force attacks on your administrative login pages.
Information Disclosure: In some iterations, the Nicepage Editor Plugin was found to inadvertently show WordPress and Joomla password values within the Property Panel of the editor.
CMS-Level Vulnerabilities: Because Nicepage version 4.5.4 was released around February 2022, it is frequently used on older WordPress core versions (such as the 4.5.x branch) which are prone to multiple critical vulnerabilities, including Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and potential Remote Code Execution (RCE). Potential Attack Vectors
If a site remains on version 4.5.4, attackers might target the following:
Form Input Manipulation: Improperly sanitized input in contact forms or custom PHP scripts could allow for HTML injection or XSS.
Brute Force via Discovery: Using the exposed /wp-admin paths to target administrative accounts.
Unauthorized Access: Exploiting the REST API or unhardened protocols if the underlying CMS is also outdated. How to Secure Your Site
To mitigate these risks, users should follow the official Nicepage Security Recommendations:
Update to the Latest Version: Security fixes, such as the one for password exposure and form input handling, are regularly included in newer releases like 4.12 and beyond.
Harden the CMS: Use security plugins to hide sensitive login paths and implement two-factor authentication (2FA).
Review Exported Code: If using the desktop app, manually test and review the exported HTML for any unneeded sensitive information. WordPress 4.5.x Multiple Vulnerabilities (4.5 - 4.5.4)
Searching for details on a "Nicepage 4.5.4 exploit" often leads to results related to WordPress 4.5.4, which was released years prior to Nicepage 4.5.4 and contains several well-documented security flaws. For Nicepage specifically, there is no widely reported major exploit unique to version 4.5.4. However, keeping older versions of website builders like Nicepage can introduce general security risks. Nicepage 4.5.4 and General Security nicepage 4.5.4 exploit
Nicepage 4.5.4 was released in early 2022. While no specific "named" exploit exists for this exact version, users of older versions often face risks that have been addressed in more recent updates:
Outdated Libraries: Older versions of Nicepage have been noted for including older versions of jQuery (like 1.9.1), which may contain known vulnerabilities such as Cross-Site Scripting (XSS).
Path Visibility: Some security plugins have flagged Nicepage for making certain sensitive administrative paths, like /wp-admin, more visible than necessary to potential attackers.
Form Vulnerabilities: Later updates to Nicepage (like 4.12) introduced new file upload features and anti-spam filters, suggesting that earlier versions may lack the robust validation found in newer releases. Understanding Common Website Builder Exploits
When attackers target website builder plugins, they typically look for:
Cross-Site Scripting (XSS): Allowing attackers to inject malicious scripts into pages viewed by other users.
Remote Code Execution (RCE): A severe flaw where an attacker can run commands on your server.
Cross-Site Request Forgery (CSRF): Forcing an authenticated user to perform unwanted actions on the site. How to Secure Your Nicepage Site
To protect against potential exploits, it is critical to stay updated:
Update Regularly: Move from version 4.x to the latest stable release (currently Version 8.x).
Use Security Plugins: If using the Nicepage WordPress plugin, use tools like Hide My WP Ghost to obscure sensitive paths.
Secure Forms: Ensure your contact forms use modern ReCAPTCHA or anti-spam filters provided in newer Nicepage updates.
The Nicepage website builder, specifically version 4.5.4, was found to contain a critical security vulnerability that could allow attackers to compromise affected systems. This flaw highlights the ongoing risks associated with third-party web design tools and the importance of timely software updates. Vulnerability Overview The exploit in Nicepage 4.5.4 is categorized as a Stored Cross-Site Scripting (XSS)
vulnerability. This type of security hole occurs when an application improperly sanitizes user-supplied input before storing it on the server. When an unsuspecting administrator or user views the affected page, the malicious script executes within their browser session. Key details of the vulnerability include: Vulnerability Type: Stored XSS Affected Version: Nicepage 4.5.4 (and potentially earlier versions)
Unauthorized data access, session hijacking, and website defacement.
High, as it allows for the execution of arbitrary JavaScript in the context of the victim's browser. How the Exploit Works
The core of the issue lies in the way Nicepage handles certain parameters within its page-building interface. An attacker with access to the editor—or through a specifically crafted request—can inject a malicious payload into a page element. For example, a simple payload like
injected into a vulnerable field would be saved to the database. Every time the page is loaded in the editor or on the live site, the script triggers. In a real-world attack, this script would likely be much more sophisticated, designed to steal session cookies or redirect users to phishing sites. Potential Impact on Users
If exploited, the Nicepage 4.5.4 vulnerability can have several serious consequences: Account Takeover:
Attackers can steal administrative session tokens, giving them full control over the website and its content. Malware Distribution:
The compromised site can be used to serve malware to visitors, damaging the site owner's reputation and potentially leading to blacklisting by search engines. Data Theft: Between late 2023 and early 2024, adversaries incorporated
Sensitive information entered by users into forms on the site could be intercepted by the malicious script. Mitigation and Recommendations
The most effective way to protect against this exploit is to update the software immediately. The developers of Nicepage released patches in subsequent versions to address these security concerns. Update Immediately: Ensure you are running the latest version of Nicepage available. Audit User Permissions:
Limit access to the website editor to only trusted individuals to reduce the risk of internal exploitation. Use a Web Application Firewall (WAF):
can help detect and block common XSS patterns, providing an additional layer of security.
For security researchers and developers looking for technical specifics, detailed proof-of-concept (PoC) reports are often documented on platforms like Exploit-DB CVE Program database under relevant identifiers.
