CVE-2024-31206 – The dectalk-tts Node package versions 1.0.0 sen... (How to Fix)

Q: What is the severity of CVE-2024-31206?

CVE-2024-31206 has a CVSS score of 8.2 (HIGH). The dectalk-tts Node package versions 1.0.0 sends API requests over unencrypted HTTP, allowing attackers to intercept and modify traffic in man-in-the-middle attacks. Anyone using the vulnerable package version is affected, as all network communication to the third-party API is exposed. This could lead to data theft, injection of malicious content, or service disruption.

📋 TL;DR

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers intercept and modify all API communications, injecting malicious audio content, stealing sensitive data transmitted via the API, or completely disrupting the text-to-speech functionality.

🟠

Likely Case

Attackers intercept API responses to modify audio output with malicious content or capture any sensitive information being processed through the text-to-speech service.

🟢

If Mitigated

With proper network controls and no sensitive data transmission, impact is limited to potential service disruption or minor data leakage.

🌐 Internet-Facing: HIGH

🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: LIKELY

Unauthenticated Exploit: ⚠️ Yes

Complexity: LOW

MITM attacks on HTTP traffic are well-understood and easily executed with common tools. No special exploit code needed beyond standard network interception techniques.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.0.1

Vendor Advisory: https://github.com/JstnMcBrd/dectalk-tts/security/advisories/GHSA-6cf6-8hvr-r68w

Restart Required: Yes

Instructions:

1. Update package.json to specify dectalk-tts version 1.0.1 or higher. 2. Run 'npm update dectalk-tts' or 'yarn upgrade dectalk-tts'. 3. Restart your application to load the updated package.

🔧 Temporary Workarounds

Network traffic monitoring and filtering

all

Monitor and block suspicious traffic to the dectalk API endpoint, though this doesn't prevent interception.

🧯 If You Can't Patch

Ensure no sensitive information is transmitted through the dectalk-tts API calls
Implement application-level verification of API responses before processing or saving them

🔍 How to Verify

Check if Vulnerable:

Check package.json or node_modules/dectalk-tts/package.json for version 1.0.0. Also inspect network traffic to confirm HTTP (not HTTPS) requests to the dectalk API.

Check Version:

npm list dectalk-tts or check package.json for "dectalk-tts": "^1.0.1"

Verify Fix Applied:

Confirm package version is 1.0.1 or higher and verify network traffic shows HTTPS requests to the API endpoint.

📡 Detection & Monitoring

Log Indicators:

HTTP (not HTTPS) requests to dectalk API endpoints
Unexpected modifications to audio output files

Network Indicators:

Unencrypted HTTP traffic to dectalk API domains
MITM attack patterns on specific API routes

SIEM Query:

source="network_traffic" AND dest_port=80 AND dest_ip IN (dectalk_api_ips) AND protocol="HTTP"
