| RustCrypto: Elliptic Curves is general purpose Elliptic Curve Cryptography (ECC) support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof. In versions 0.14.0-pre.0 and 0.14.0-rc.0, a critical vulnerability exists in the SM2 Public Key Encryption (PKE) implementation where the ephemeral nonce k is generated with severely reduced entropy. A unit mismatch error causes the nonce generation function to request only 32 bits of randomness instead of the expected 256 bits. This reduces the security of the encryption from a 128-bit level to a trivial 16-bit level, allowing a practical attack to recover the nonce k and decrypt any ciphertext given only the public key and ciphertext. This issue has been patched via commit e4f7778. |
| libexpat before 2.7.6 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document. |
| Rapid7 Nexpose versions 6.4.50 and later are vulnerable to an insufficient entropy issue in the CredentialsKeyStorePassword.generateRandomPassword() method. When updating legacy keystore passwords, the application generates a new password with insufficient length (7-12 characters) and a static prefix 'p', resulting in a weak keyspace. An attacker with access to the nsc.ks file can brute-force this password using consumer-grade hardware to decrypt stored credentials. |
| The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle. |
| In Progress® Telerik® UI for AJAX, versions prior to 2026.1.225, an insufficient entropy vulnerability exists in RadAsyncUpload, where a predictable temporary identifier, based on timestamp and filename, can enable collisions and file content tampering. |
| A privilege escalation vulnerability in Microchip IStaX allows an authenticated low-privileged user to recover a shared per-device cookie secret from their own webstax_auth session cookie and forge a new cookie with administrative privileges.This issue affects IStaX before 2026.03. |
| ValiCert Enterprise Validation Authority (EVA) Administration Server 3.3 through 4.2.1 uses insufficiently random data to (1) generate session tokens for HSMs using the C rand function, or (2) generate certificates or keys using /dev/urandom instead of another source which blocks when the entropy pool is low, which could make it easier for local or remote attackers to steal tokens or certificates via brute force guessing. |
| VPN Firewall developed by QNO Technology has a Insufficient Entropy vulnerability, allowing unauthenticated remote attackers to obtain any logged-in user session through brute-force attacks and subsequently log into the system. |
| Thinbus Javascript Secure Remote Password is a browser SRP6a implementation for zero-knowledge password authentication. In versions 2.0.0 and below, a protocol compliance bug causes the client to generate a fixed 252 bits of entropy instead of the intended bit length of the safe prime (defaulted to 2048 bits). The client public value is being generated from a private value that is 4 bits below the specification. This reduces the protocol's designed security margin it is now practically exploitable. The servers full sized 2048 bit random number is used to create the shared session key and password proof. This is fixed in version 2.0.1. |
| The KDE Connect verification-code protocol before 2025-04-18 uses only 8 characters and therefore allows brute-force attacks. This affects KDE Connect before 1.33.0 on Android, KDE Connect before 25.04 on desktop, KDE Connect before 0.5 on iOS, Valent before 1.0.0.alpha.47, and GSConnect before 59. |
| Arteco Web Client DVR/NVR contains a session hijacking vulnerability with insufficient session ID complexity that allows remote attackers to bypass authentication. Attackers can brute force session IDs within a specific numeric range to obtain valid sessions and access live camera streams without authorization. |
| A CWE-331: Insufficient Entropy vulnerability exists that could cause root password discovery when the
password generation algorithm is reverse engineered with access to installation or upgrade artifacts. |
| An insufficient entropy vulnerability was found in glibc. The getrandom and arc4random family of functions may return predictable randomness if these functions are called again after the fork, which happens concurrently with a call to any of these functions. |
| Bangkok Medical Software HOSxP XE v4.64.11.3 was discovered to contain a hardcoded IDEA Key-IV pair in the HOSxPXE4.exe and HOS-WIN32.INI components. This allows attackers to access sensitive information. |
| Net::Xero 0.044 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Specifically Net::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function. |
| An insufficient entropy vulnerability was found in the Openshift Console. In the authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a Cross-Site Request Forgery (CSRF) attack if the state parameter is used inefficiently. This flaw allows logging into the victim’s current application account using a third-party account without any restrictions. |
| Chilkat before v9.5.0.98, allows attackers to obtain sensitive information via predictable PRNG in ChilkatRand::randomBytes function. |
| DBIx::Class::EncodedColumn use the rand() function, which is not cryptographically secure to salt password hashes.
This vulnerability is associated with program files lib/DBIx/Class/EncodedColumn/Digest.pm.
This issue affects DBIx::Class::EncodedColumn until 0.00032. |
| The DPA countermeasures on Silicon Labs' Series 2 devices are not reseeded periodically as they should be. This may allow an attacker to eventually extract secret keys through a DPA attack. |
| Data::Entropy for Perl 0.007 and earlier use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. |
