Jahlives: >> Openssl Encrypt >> 1.0.2 Security Vulnerabilities
openssl_encrypt versions before 1.4.0 contain a plugin sandbox bypass vulnerability where the PluginImportGuard blocks a different set of modules than the AST analyzer's DANGEROUS_MODULES set. Attackers can bypass AST analysis through string obfuscation or encoding to import unblocked dangerous modules like sys, shutil, multiprocessing, importlib, and pickle for arbitrary code execution.

openssl_encrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords protecting legacy encrypted files compared to standard PBKDF2 implementations.

openssl_encrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks.

openssl_encrypt versions before 1.4.0 contain an authentication bypass vulnerability in CamelliaCipher that disables HMAC tag generation and verification when the PYTEST_CURRENT_TEST environment variable is set. Attackers with code execution can set this environment variable to produce unauthenticated ciphertext and bypass integrity protection on encrypted data.

openssl_encrypt versions before 1.4.0 contain a missing ownership verification vulnerability in the revoke_key method that allows authenticated clients to revoke any other client's key. Attackers can revoke arbitrary keys by providing a valid ML-DSA signature, bypassing the intended ownership restriction.

openssl_encrypt versions before 1.4.0 contain an insecure default configuration that trusts the entire RFC 1918 private address space in IntegrityProxyConfig trusted_proxies. Attackers on private networks can forge client certificate headers to bypass mTLS authentication when ProxyAuth validation is relaxed or modified.

openssl_encrypt versions before 1.4.0 contain a vulnerability in PublicKeyBundle.from_dict() that creates key bundles from untrusted data without verifying signatures. Attackers can call from_dict() followed by to_identity() without signature verification to encrypt data using attacker-controlled public keys, leaking secrets.

openssl_encrypt versions before 1.4.0 use an in-memory rate limiter for TOTP brute-force protection that is not shared across workers and is lost on server restart. Attackers can distribute authentication attempts across multiple server instances or retry immediately after a restart to bypass rate limiting protections.

openssl_encrypt versions before 1.4.0 contain an information disclosure vulnerability in the /ready endpoint that returns full database exception strings to unauthenticated callers. Attackers can trigger database errors to extract sensitive information including hostnames, IP addresses, connection parameters, and potentially credentials from exception messages.

openssl_encrypt versions before 1.4.0 accept refresh tokens as URL query parameters in keyserver and telemetry server routes. Attackers can extract tokens from server logs, proxy logs, browser history, and HTTP Referer headers to gain unauthorized access.
