CVE-2025-45766

7.0 HIGH

📋 TL;DR

Poco v1.14.1-release contains weak encryption implementations that could allow attackers to decrypt sensitive data if applications don't properly configure encryption parameters. This affects applications using Poco's cryptography components with default or weak settings. The vulnerability is disputed as the library expects applications to set appropriate key lengths.

💻 Affected Systems

Products:
  • Poco C++ Libraries
Versions: v1.14.1-release (specifically mentioned, potentially earlier versions if same code exists)
Operating Systems: All platforms where Poco is used (Linux, Windows, macOS, etc.)
Default Config Vulnerable: ✅ No
Notes: Vulnerability depends on how applications configure and use Poco's encryption components. The library expects applications to set appropriate parameters.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of encrypted data including passwords, session tokens, and sensitive information leading to authentication bypass and data theft.

🟠

Likely Case

Partial data exposure where attackers can decrypt some weakly encrypted information, potentially revealing sensitive configuration or user data.

🟢

If Mitigated

Minimal impact if applications properly configure strong encryption parameters and follow security best practices.

🌐 Internet-Facing: MEDIUM - Applications exposed to the internet using weak encryption could have data intercepted and decrypted.
🏢 Internal Only: LOW - Internal systems with proper network segmentation and encryption configuration would have reduced exposure.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires access to encrypted data and understanding of how the target application uses Poco's encryption. The GitHub gist shows technical details but not a complete exploit.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not specified

Vendor Advisory: https://github.com/pocoproject/poco

Restart Required: No

Instructions:

1. Review Poco GitHub repository for updates. 2. If no official patch, ensure applications configure strong encryption parameters. 3. Consider updating to newer Poco versions if available.

🔧 Temporary Workarounds

Configure Strong Encryption Parameters

all

Ensure applications using Poco set appropriate key lengths and encryption algorithms according to security best practices.

Application Code Review

all

Audit application code to verify proper encryption configuration and usage of Poco cryptography components.

🧯 If You Can't Patch

  • Implement additional encryption layer using properly configured cryptography libraries
  • Restrict access to systems using vulnerable Poco versions and monitor for suspicious activity

🔍 How to Verify

Check if Vulnerable:

Check if application uses Poco v1.14.1-release and review encryption configuration in source code.

Check Version:

Check Poco version in build configuration or via library headers/version information.

Verify Fix Applied:

Verify applications configure strong encryption parameters (minimum 256-bit keys for symmetric encryption, proper RSA key sizes).

📡 Detection & Monitoring

Log Indicators:

  • Unusual decryption failures
  • Cryptography-related errors in application logs

Network Indicators:

  • Intercepted encrypted data with weak encryption characteristics
