CVE-2020-18220

DoraCMS v2.1.1 and earlier uses AES-CBC without a random salt/IV for password encryption, exposing passwords to dictionary attacks. The issue is documented across multiple sources (CVE-2020-18220) and indicates weak encoding rather than a broader vulnerability. Affected component is the password-...

Hack Breaks PDF Encryption, Opens Content to Attackers

Researchers in Germany have invented a new hack that can allow someone to break the encryption of PDF files and access their content — or even forge signed PDF files under certain circumstances. A team from Ruhr University Bochum, FH Münster University of Applied Sciences and Hackmanit GmbH...

CVE-2019-8919

The seadroid aka Seafile Android Client application through 2.2.13 for Android always uses the same Initialization Vector IV with Cipher Block Chaining CBC Mode to encrypt private data, making it easier to conduct chosen-plaintext attacks or dictionary attacks...

Denial Of Service (DoS) Through Buffer Over-read

OpenSSL is vulnerable to denial of service DoS attacks and possibly other attacks. These attacks are possible because there is an integer underflow when TLS 1.1, TLS 1.2 or DTLS is used with CBC encryption...

CVE-2017-3226

Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption i.e., setting the configuration parameter CONFIGENVAES=y read environment variables from disk as the encrypte...

CVE-2017-3226

CVE-2017-3226 concerns Das U-Boot’s AES-CBC environment encryption (CONFIG_ENV_AES=y). A crafted two‑byte sequence in the encrypted environment data can trigger an error during environment variable parsing, which is improperly handled and leads to an immediate process termination with a debugging...

CVE-2017-3226 Das U-Boot's AES-CBC encryption feature improperly handles an error condition and may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data

Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption i.e., setting the configuration parameter CONFIGENVAES=y read environment variables from disk as the encrypte...

FreeBSD : kde-runtime -- incorrect CBC encryption handling (7a8a74d1-9c34-11e4-a40b-5453ed2e2b49)

Valentin Rusu reports : Until KDE Applications 14.12.0, kwalletd incorrectly handled CBC encryption blocks when encrypting secrets in kwl files. The secrets were still encrypted, but the result binary data corresponded to an ECB encrypted block instead of CBC. The ECB encryption algorithm, even i...
