CVE-2019-5440

CVE-2019-5440 affects Revive Adserver versions prior to 4.2.1. The password recovery token is generated via generateRecoveryId() using PHP uniqid, which relies on the current time and provides weak entropy, potentially enabling authentication bypass through the password recovery feature. Affected...

CVE-2019-5440: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Use of cryptographically weak PRNG in the password recovery token generation of Revive Adserver v4.2.1 causes a potential authentication bypass attack if an attacker exploits the password recovery functionality. In lib/OA/Dal/PasswordRecovery.php, the function generateRecoveryId generates a...

PT-2019-17670

Name of the Vulnerable Software and Affected Versions Revive Adserver versions prior to 4.2.1 Description The issue is related to the use of a cryptographically weak PRNG in the password recovery token generation. This could potentially lead to an authentication bypass attack if the password...

Cryptographically Weak PRNG in generate-password

Affected versions of generate-password generate random values that are biased towards certain characters depending on the chosen character sets. This may result in guessable passwords. Recommendation Update to version 1.4.1 or later...

GHSA-6QQF-VVCR-7QRV Cryptographically Weak PRNG in generate-password

Affected versions of generate-password generate random values that are biased towards certain characters depending on the chosen character sets. This may result in guessable passwords. Recommendation Update to version 1.4.1 or later...

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

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

EulerOS Virtualization 3.0.1.0 : libgcrypt (EulerOS-SA-2019-1448)

According to the version of the libgcrypt package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability : - A design flaw was found in the libgcrypt PRNG Pseudo-Random Number Generator. An attacker able to obtain the first 580 bytes of th...

CVE-2019-11842: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID...

CVE-2019-11808

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

CVE-2019-11808

Ratpack versions before 1.6.1 generate a session ID using a cryptographically weak PRNG in the JDK's ThreadLocalRandom. This means that if an attacker can determine a small window for the server start time and obtain a session ID value, they can theoretically determine the sequence of session IDs...

CVE-2019-11808

CVE-2019-11808 affects Ratpack versions before 1.6.1, where session IDs are generated using a cryptographically weak PRNG in the JDK’s ThreadLocalRandom. The consequence is that if an attacker can narrow the server-start window and observe a session ID, they could theoretically determine the sequ...
