CVE-2025-47777

Comprehensive Technical Analysis of CVE-2025-47777

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-47777 CVSS Score: 9.6

The vulnerability in question affects the 5ire cross-platform desktop artificial intelligence assistant and model context protocol client. Versions prior to 0.11.1 are susceptible to stored cross-site scripting (XSS) in chatbot responses due to insufficient sanitization. This XSS vulnerability can be leveraged to achieve Remote Code Execution (RCE) through unsafe Electron protocol handling and exposed Electron APIs.

Severity Evaluation:

• CVSS Base Score: 9.6 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates a critical vulnerability that can be easily exploited with severe consequences, including potential data breaches, system compromises, and unauthorized access.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Stored XSS: An attacker can inject malicious scripts into chatbot responses, which are then stored and executed when a user interacts with the chatbot.
2. Unsafe Electron Protocol Handling: The malicious scripts can exploit unsafe Electron protocol handling to execute arbitrary code on the user's system.
3. Exposed Electron APIs: The exposed Electron APIs provide additional attack surfaces that can be exploited to gain deeper access to the system.

Exploitation Methods:

1. Script Injection: An attacker injects a malicious script into a chatbot response.
2. Protocol Manipulation: The injected script manipulates Electron protocols to execute arbitrary code.
3. API Exploitation: The attacker leverages exposed Electron APIs to perform unauthorized actions on the system.

3. Affected Systems and Software Versions

Affected Systems:

• All users of 5ire client versions prior to 0.11.1.
• Particularly those interacting with untrusted chatbots or pasting external content.

Software Versions:

• 5ire client versions prior to 0.11.1.

4. Recommended Mitigation Strategies

Immediate Actions:

1. Update Software: Upgrade to 5ire client version 0.11.1 or later, which contains the patch for the issue.
2. Disable Untrusted Chatbots: Temporarily disable interactions with untrusted chatbots until the patch is applied.
3. Sanitize Inputs: Implement additional input sanitization measures to prevent script injection.

Long-Term Strategies:

1. Regular Patching: Ensure regular updates and patches are applied to all software.
2. Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
3. User Education: Educate users on the risks of interacting with untrusted content and the importance of updating software.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-47777 highlights the ongoing challenges in securing cross-platform applications, particularly those built on frameworks like Electron. The vulnerability underscores the importance of robust input sanitization, secure protocol handling, and minimizing exposed APIs. It also emphasizes the need for continuous monitoring and prompt patching to mitigate risks.

6. Technical Details for Security Professionals

Technical Overview:

• Stored XSS: The vulnerability arises from insufficient sanitization of chatbot responses, allowing malicious scripts to be stored and executed.
• Electron Protocol Handling: Unsafe handling of Electron protocols enables the execution of arbitrary code through injected scripts.
• Exposed Electron APIs: Exposed APIs provide additional attack vectors that can be exploited to gain unauthorized access and control.

Mitigation Steps:

1. Input Sanitization: Ensure all user inputs are properly sanitized to prevent script injection.
2. Secure Protocol Handling: Implement secure protocol handling mechanisms to prevent arbitrary code execution.
3. API Security: Minimize exposed APIs and implement strict access controls to prevent unauthorized actions.
