RabbitMQ is a multi-protocol messaging and streaming broker. In affected versions the shovel and federation plugins perform URI obfuscation in their worker (link) state. The encryption key used to encrypt the URI was seeded with a predictable secret. This means that in case of certain exceptions related to Shovel and Federation plugins, reasonably easily deobfuscatable data could appear in the node log. Patched versions correctly use a cluster-wide secret for that purpose. This issue has been addressed and Patched versions: `3.10.2`, `3.9.18`, `3.8.32` are available. Users unable to upgrade should disable the Shovel and Federation plugins.

An issue was discovered on the D-Link DWR-932B router. WPS PIN generation is based on srand(time(0)) seeding.

In Quest KACE Systems Management Appliance (SMA) through 12.0, predictable token generation occurs when appliance linking is enabled.

The aescrypt gem 1.0.0 for Ruby does not randomize the CBC IV for use with the AESCrypt.encrypt and AESCrypt.decrypt functions, which allows attackers to defeat cryptographic protection mechanisms via a chosen plaintext attack.

konzept-ix publiXone before 2020.015 allows attackers to download files by iterating over the IXCopy fileID parameter.

MyBB (aka MyBulletinBoard) 1.4.2 uses insufficient randomness to compose filenames of uploaded files used as attachments, which makes it easier for remote attackers to read these files by guessing filenames.

Typo 5.1.3 and earlier uses a hard-coded salt for calculating password hashes, which makes it easier for attackers to guess passwords via a brute force attack.

LibreOffice supports the storage of passwords for web connections in the user’s configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the required initialization vector for encryption was always the same which weakens the security of the encryption making them vulnerable if an attacker has access to the user's configuration data. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.1.

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.

Henschen & Associates court document management software does not sufficiently randomize file names of cached documents, allowing a remote, unauthenticated attacker to access restricted documents.

There is insecure algorithm vulnerability in Huawei products. A module uses less random input in a secure mechanism. Attackers can exploit this vulnerability by brute forcing to obtain sensitive message. This can lead to information leak. Affected product versions include:USG9500 versions V500R001C30SPC200, V500R001C60SPC500,V500R005C00SPC200;USG9520 versions V500R005C00;USG9560 versions V500R005C00;USG9580 versions V500R005C00.

The DNS client in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, and Vista uses predictable DNS transaction IDs, which allows remote attackers to spoof DNS responses.

actions.php in WebPortal CMS 0.6-beta generates predictable passwords containing only the time of day, which makes it easier for remote attackers to obtain access to any account via a lostpass action.

An issue was discovered in Aviatrix Controller before R5.3.1151. An encrypted file containing credentials to unrelated systems is protected by a three-character key.

Non-reinitialisation of random data in the advertising payload in COVIDSafe v1.0.15 and v1.0.16 allows a remote attacker to re-identify Android devices running COVIDSafe by scanning for their advertising beacons.

An issue was discovered on Mofi Network MOFI4500-4GXeLTE 4.0.8-std devices. The one-time password algorithm for the undocumented system account mofidev generates a predictable six-digit password.

airhost.exe in Zoom Client for Meetings 4.6.11 uses 3423423432325249 as the Initialization Vector (IV) for AES-256 CBC encryption. NOTE: the vendor states that this IV is used only within unreachable code

A cryptograhic flaw exists in Magento 2.1 prior to 2.1.18, Magento 2.2 prior to 2.2.9, Magento 2.3 prior to 2.3.2. A weak cryptograhic mechanism is used to generate the intialization vector in multiple security relevant contexts.

Predictable seed generation in the security access mechanism of UDS in the Blind Spot Protection Sensor ECU in Nissan Altima (2022) allows attackers to predict the requested seeds and bypass security controls via repeated ECU resets and seed requests.

An issue was discovered in damiCMS V6.0.1. It relies on the PHP time() function for cookies, which makes it possible to determine the cookie for an existing admin session via 10800 guesses.

A vulnerability, which was classified as problematic, was found in projectsend up to r1605. Affected is the function generate_random_string of the file includes/functions.php of the component Password Reset Token Handler. The manipulation leads to insufficiently random values. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. Upgrading to version r1720 is able to address this issue. The name of the patch is aa27eb97edc2ff2b203f97e6675d7b5ba0a22a17. It is recommended to upgrade the affected component.

SIF is an open source implementation of the Singularity Container Image Format. The `siftool new` command and func siftool.New() produce predictable UUID identifiers due to insecure randomness in the version of the `github.com/satori/go.uuid` module used as a dependency. A patch is available in version >= v1.2.3 of the module. Users are encouraged to upgrade. As a workaround, users passing CreateInfo struct should ensure the `ID` field is generated using a version of `github.com/satori/go.uuid` that is not vulnerable to this issue.

Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.

An instance of small space of random values in the RPC API of FortiSandbox before 4.0.0 may allow an attacker in possession of a few information pieces about the state of the device to possibly predict valid session IDs.

The OKLOK (3.1.1) mobile companion app for Fingerprint Bluetooth Padlock FB50 (2.3) has an information-exposure issue. In the mobile app, an attempt to add an already-bound lock by its barcode reveals the email address of the account to which the lock is bound, as well as the name of the lock. Valid barcode inputs can be easily guessed because barcode strings follow a predictable pattern. Correctly guessed valid barcode inputs entered through the app interface disclose arbitrary users' email addresses and lock names.
