bkcrack

bkcrack Biham と Kocher の既知平文攻撃を使用してレガシーZIP暗号化を解読します。 概要 ZIPアーカイブには、圧縮や暗号化が施された多数のエントリが含まれる場合があります。 特に、エントリは従来のPKWARE暗号化、レガシー暗号化、またはZipCryptoと呼ばれるパスワードベースの対称暗号アルゴリズムで暗号化できます。 このアルゴリズムは、疑似ランダムバイトストリーム（キーストリーム）を生成し、エントリの内容（平文）にXORして暗号化データ（暗号文）を生成します。...

Nextcloud Server 19.0.1 Encryption Vulnerability (NC-SA-2020-039)

Nextcloud Server is prone to a vulnerability where it is possible to downgrade the encryption scheme and break the integrity through known-plaintext attack. SPDX-FileCopyrightText: 2020 Greenbone AG Some text descriptions might be excerpted from a referenced sources, and are Copyright C by the...

Nextcloud: Downgrade encryption scheme and break integrity through known-plaintext attack

The idea behind the Server Side Encryption is that you can move your encrypted files to an external party without that external party being able to to read or modify those files. Some time ago, Nextcloud switched from unauthenticated CFB cipher block mode to authenticated CTR cipher block mode in...

CVE-2014-2319

The Encrypt Files feature in ConeXware PowerArchiver before 14.02.05 uses legacy ZIP encryption even if the AES 256-bit selection is chosen, which makes it easier for context-dependent attackers to obtain sensitive information via a known-plaintext attack...

CVE-2007-6192

The CVE-2007-6192 entry describes an information disclosure vulnerability in the Citrix NetScaler Web Management Interface (NetScaler 8.0 build 47.8). The issue arises from using weak encryption to protect cookie contents by XORing sensitive values (including credentials) with a fixed key stream,...

PasswordSafe 3.0 beta, when running on Windows before XP, uses a weak random number generator C++ rand function during generation of the database encryption key, which makes it easier for attackers to decrypt the database and steal passwords by generating keys for all possible rand seed values an...

CVE-2006-1378

CVE-2006-1378 concerns PasswordSafe 3.0 beta running on Windows versions prior to XP, where the database encryption key is generated using the weak C++ rand() RNG. The underlying root cause is the predictability of rand(), which enables an attacker to enumerate possible seed values and, via a kno...
