CWE-338

Allowed

Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Abstraction: Base · Status: Draft

The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong.

Title
WebService::Xero 0.11 for Perl uses insecure rand() function for cryptographic functions
Summary
WebService::Xero 0.11 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically WebService::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.

CVE-2024-47126 (GCVE-0-2024-47126)

Vulnerability from cvelistv5 – Published: 2024-09-26 17:26 – Updated: 2024-10-17 17:33

Title
Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in goTenna Pro
Summary
The goTenna Pro App does not use SecureRandom when generating passwords for sharing cryptographic keys. The random function in use makes it easier for attackers to brute force this password if the broadcasted encryption key is captured over RF. This only applies to the optional broadcast of an encryption key, so it is advised to share the key with local QR code for higher security operations.

CVE-2024-45723 (GCVE-0-2024-45723)

Vulnerability from cvelistv5 – Published: 2024-09-26 17:37 – Updated: 2024-10-17 16:56
VLAI
Title
goTenna Pro ATAK Plugin Use of Cryptographically Weak Pseudo-Random Number Generator
Summary
The goTenna Pro ATAK Plugin does not use SecureRandom when generating passwords for sharing cryptographic keys. The random function in use makes it easier for attackers to brute force this password if the broadcasted encryption key is captured over RF. This only applies to the optional broadcast of an encryption key, so it is advised to share the key with local QR code for higher security operations.

CVE-2024-38353 (GCVE-0-2024-38353)

Vulnerability from cvelistv5 – Published: 2024-07-10 19:50 – Updated: 2024-08-02 04:04

Title
CodiMD - Missing Image Access Controls and Unauthorized Image Access
Summary
CodiMD allows realtime collaborative markdown notes on all platforms. CodiMD before 2.5.4 is missing authentication and access control vulnerability allowing an unauthenticated attacker to gain unauthorised access to image data uploaded to CodiMD. CodiMD does not require valid authentication to access uploaded images or to upload new image data. An attacker who can determine an uploaded image's URL can gain unauthorised access to uploaded image data. Due to the insecure random filename generation in the underlying Formidable library, an attacker can determine the filenames for previously uploaded images and the likelihood of this issue being exploited is increased. This vulnerability is fixed in 2.5.4.

Title
Apache StreamPipes, Apache StreamPipes: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in Recovery Token Generation
Summary
Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) vulnerability in Apache StreamPipes user self-registration and password recovery mechanism. This allows an attacker to guess the recovery token in a reasonable time and thereby to take over the attacked user's account. This issue affects Apache StreamPipes: from 0.69.0 through 0.93.0. Users are recommended to upgrade to version 0.95.0, which fixes the issue.

CVE-2023-48224 (GCVE-0-2023-48224)

Vulnerability from cvelistv5 – Published: 2023-11-15 20:53 – Updated: 2024-08-29 15:02

Title
Cryptographically Weak Generation of One-Time Codes for Identity Verification in ethyca-fides
Summary
Fides is an open-source privacy engineering platform for managing the fulfillment of data privacy requests in a runtime environment, and the enforcement of privacy regulations in code. The Fides Privacy Center allows data subject users to submit privacy and consent requests to data controller users of the Fides web application. Privacy requests allow data subjects to submit a request to access all person data held by the data controller, or delete/erase it. Consent request allows data subject users to modify their privacy preferences for how the data controller uses their personal data e.g. data sales and sharing consent opt-in/opt-out. If `subject_identity_verification_required` in the `[execution]` section of `fides.toml` or the env var `FIDES__EXECUTION__SUBJECT_IDENTITY_VERIFICATION_REQUIRED` is set to `True` on the fides webserver backend, data subjects are sent a one-time code to their email address or phone number, depending on messaging configuration, and the one-time code must be entered in the Privacy Center UI by the data subject before the privacy or consent request is submitted. It was identified that the one-time code values for these requests were generated by the python `random` module, a cryptographically weak pseduo-random number generator (PNRG). If an attacker generates several hundred consecutive one-time codes, this vulnerability allows the attacker to predict all future one-time code values during the lifetime of the backend python process. There is no security impact on data access requests as the personal data download package is not shared in the Privacy Center itself. However, this vulnerability allows an attacker to (i) submit a verified data erasure request, resulting in deletion of data for the targeted user and (ii) submit a verified consent request, modifying a user's privacy preferences. The vulnerability has been patched in Fides version `2.24.0`. Users are advised to upgrade to this version or later to secure their systems against this threat. There are no known workarounds for this vulnerability.

Mitigation
Implementation

Use functions or hardware which use a hardware-based random number generation for all crypto. This is the recommended solution. Use CyptGenRandom on Windows, or hw_rand() on Linux.
