Overview
CVE-2025-13181 identifies a cross-site scripting (XSS) vulnerability present in pojoin h3blog version 1.0. This vulnerability allows an attacker to inject malicious scripts into web pages viewed by other users. The affected component resides within the /admin/cms/material/add file, specifically targeting the ‘Name’ argument.
Technical Details
The XSS vulnerability in pojoin h3blog 1.0 arises from insufficient input validation and sanitization of the ‘Name’ parameter within the /admin/cms/material/add endpoint. An attacker can inject arbitrary JavaScript code through this parameter. When a user interacts with the application, the injected script executes within their browser context, potentially leading to account compromise, data theft, or defacement of the website.
The vulnerability is remotely exploitable and has been publicly disclosed, meaning that proof-of-concept (PoC) exploits are available.
CVSS Analysis
- CVSS Score: 3.5
- Severity: LOW
Despite the low CVSS score, XSS vulnerabilities should be taken seriously. A seemingly low-impact XSS vulnerability can be chained with other vulnerabilities to create a higher impact attack.
Possible Impact
The exploitation of this XSS vulnerability can lead to:
- Account Hijacking: An attacker can steal user session cookies and impersonate legitimate users.
- Data Theft: Sensitive information displayed on the page can be exfiltrated.
- Website Defacement: The attacker can modify the content of the affected page, displaying malicious or misleading information.
- Redirection to Malicious Sites: Users can be redirected to phishing or malware distribution websites.
Mitigation and Patch Steps
To mitigate this vulnerability, the following steps should be taken:
- Apply the Patch: Check the pojoin h3blog website for any available patches or updates that address this vulnerability. Upgrade to the latest version as soon as possible.
- Input Validation and Sanitization: Implement robust input validation and sanitization measures on all user-supplied data, especially the ‘Name’ parameter in the
/admin/cms/material/addendpoint. Use appropriate encoding techniques to prevent the execution of malicious scripts. - Content Security Policy (CSP): Implement a Content Security Policy (CSP) to restrict the sources from which the browser is allowed to load resources. This can help prevent the execution of injected scripts.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests targeting the vulnerability.
