In this article, we'll be uncovering the details of a recently discovered cross-site scripting (XSS) vulnerability in WBCE CMS v1.5.4. Specifically, the vulnerability is found in the Modify Page module and is assigned the CVE identifier CVE-2022-45012. By exploiting this vulnerability, an attacker can execute arbitrary web scripts or HTML through a carefully crafted payload. We'll explain the vulnerability, show an example of how it can be exploited, provide code snippets, and point to the original references related to this issue.
What is WBCE CMS?
WBCE CMS, or WebsiteBaker Community Edition, is a popular content management system (CMS) designed for easy website creation and management. It's an open-source platform written in PHP, providing users with a friendly interface and various tools for building and managing content-rich websites. However, like any other software, it is not immune to security issues.
Vulnerability Details (CVE-2022-45012)
The vulnerability in question is a cross-site scripting (XSS) issue found in the Modify Page module of WBCE CMS v1.5.4. When a user with administrative privileges accesses this module to make changes to a page, they encounter a "Source" field, designed to accept HTML input. However, this field does not properly sanitize input, allowing an attacker to inject arbitrary web scripts or HTML via a crafted payload.
The danger of this vulnerability is that it can allow an attacker to execute malicious actions on the website, compromise user data, or gain control over affected CMS installations.
Exploitation Example
To exploit this vulnerability, an attacker needs to craft a payload containing malicious script and inject it into the vulnerable "Source" field in the Modify Page module. Here's an example of such payload:
<script>alert('XSS Attack!');</script>
When an unsuspecting user visits a page containing this injected script, their browser would interpret the script and display an alert message with the text "XSS Attack!". While this example is relatively benign, a more sophisticated attacker could craft a payload that steals user data or executes other malicious actions.
Mitigation and Recommendations
The developers of WBCE CMS have been made aware of this issue and are likely working on a fix. In the meantime, users of WBCE CMS v1.5.4 are recommended to take the following actions to mitigate the risk associated with CVE-2022-45012:
Limit the access to the Modify Pages module to trusted users with administrative privileges.
3. Manually review and sanitize any suspicious HTML input in the Source field before submitting changes.
