Technical details
The linqi application is vulnerable to two primary cryptographic weaknesses: the use of hardcoded cryptographic keys (CWE-321) and a cryptographically weak PRNG for Initialization Vector (IV) generation (CWE-338). Specifically, the application uses a limited ASCII charset and a weak algorithm to generate IVs for AES/CBC encryption. These flaws make known-plaintext attacks feasible. An attacker with local access and low privileges can exploit these vulnerabilities to decrypt obfuscated strings within configuration files, such as 'appsettings.json', potentially revealing plaintext database credentials and other sensitive ConnectionString values.
