Overview
CVE-2025-13182 describes a Cross-Site Scripting (XSS) vulnerability discovered in pojoin h3blog version 1.0. This vulnerability allows a remote attacker to inject malicious scripts into the application via the ‘Title’ argument of the /admin/cms/category/addtitle file. The vulnerability has been classified as low severity and a proof-of-concept exploit is publicly available.
Technical Details
The XSS vulnerability exists within the /admin/cms/category/addtitle endpoint. By manipulating the Title parameter, an attacker can inject arbitrary JavaScript code that will be executed in the context of a user’s browser when they interact with the affected page. This could lead to session hijacking, defacement, or other malicious activities.
The affected function within the specified file does not properly sanitize or encode user-supplied input, allowing the injection of malicious scripts. The vulnerability can be exploited remotely without any specific authentication requirements, though access to the admin panel is likely required to trigger it effectively.
CVSS Analysis
- Severity: LOW
- CVSS Score: 3.5
A CVSS score of 3.5 indicates a Low severity vulnerability. While exploitable remotely, the impact is limited, likely requiring some level of user interaction or specific preconditions to be effectively exploited. The attack complexity is relatively low.
Possible Impact
Although classified as low severity, the potential impact of CVE-2025-13182 should not be ignored. Successful exploitation can lead to:
- Website Defacement: An attacker could modify the appearance of the affected page to display misleading or malicious content.
- Session Hijacking: Injected scripts could be used to steal user session cookies, allowing the attacker to impersonate the user.
- Phishing Attacks: Malicious scripts can be used to redirect users to phishing websites designed to steal credentials.
Mitigation or Patch Steps
To mitigate this vulnerability, the following steps are recommended:
- Input Validation: Implement robust input validation and sanitization for all user-supplied data, especially for the
Titleparameter in the/admin/cms/category/addtitleendpoint. Ensure that HTML and JavaScript code are properly encoded or stripped from the input. - Output Encoding: Encode all data before it is displayed to the user, especially data that originates from user input.
- Update h3blog: Check for and apply any available patches or updates released by pojoin for h3blog 1.0. Contact the vendor for patch information if necessary.
- Web Application Firewall (WAF): Consider deploying a WAF to detect and block XSS attacks. Configure the WAF with appropriate rules to filter malicious requests.
