CVE-2025-8211: Roothub Vulnerable to Cross-Site Scripting (XSS)
Stay vigilant! A cross-site scripting (XSS) vulnerability has been identified in Roothub, potentially allowing attackers to inject malicious scripts into the web application.
🔍 TL;DR Summary
Roothub version 2.6 and earlier is susceptible to a reflected cross-site scripting (XSS) vulnerability. An attacker with low privileges can inject malicious scripts into the `Edit` function within the `SystemConfigAdminController.java` file, potentially compromising user sessions and data. A proof-of-concept exploit is publicly available, increasing the risk of exploitation.
🚨 Vulnerability Details
- CVE ID: CVE-2025-8211
- Description: A cross-site scripting (XSS) vulnerability exists in Roothub up to version 2.6. Specifically, the `Edit` function within the `src/main/java/cn/roothub/web/admin/SystemConfigAdminController.java` file is affected. This allows an attacker to inject arbitrary web scripts into the browser of a user.
- CVSS Score and Vector:
- CVSS v3.1: 3.5 (LOW) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N
- CVSS v4.0: 5.1 (MEDIUM) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
The CVSS v3.1 score indicates a low severity. An attacker needs to have low privileges and requires user interaction (clicking a link) to execute the script. While the impact on confidentiality and availability is none, integrity can be affected. The CVSS v4.0 score is slightly higher (Medium) because it considers exploit maturity and attack requirements.
- Exploit Requirements: An attacker needs to be authenticated with low privileges and requires a victim to interact with a malicious link.
- Affected Vendor, Product, Version: Roothub up to version 2.6.
- CWE: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) & CWE-94 (Improper Control of Generation of Code ('Code Injection')). This means the application doesn't properly sanitize user-supplied data before including it in the HTML output, potentially allowing attackers to inject malicious scripts.
📅 Timeline of Events
- 2025-07-26: Vulnerability reported to VulDB.
- 2025-07-26: CVE ID CVE-2025-8211 assigned.
- Unknown: Public exploit available.
🧠 Exploitability & Real-World Risk
Given the public availability of the exploit, the risk of exploitation is elevated. An attacker could leverage this vulnerability to steal user session cookies, deface the website, or redirect users to malicious websites. Even though the attacker requires some privileges the real-world risk is elevated by the PoC exploit.
🛠️ Recommendations
- Apply Patch: Upgrade to the latest version of Roothub, if a patch is available.
- Input Validation: Implement robust input validation and sanitization techniques to prevent the injection of malicious scripts.
- Content Security Policy (CSP): Implement a strict Content Security Policy (CSP) to mitigate the impact of XSS attacks.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
🧪 Technical Insight
The vulnerability lies in the `Edit` function of `SystemConfigAdminController.java`. The application fails to properly sanitize user-provided input before reflecting it in the HTML output. By crafting a malicious request, an attacker can inject JavaScript code that will be executed in the victim's browser.
