Cryptographically Weak PRNG in randomatic

Moderate severity GitHub Reviewed Published Oct 9, 2018 to the GitHub Advisory Database • Updated Sep 8, 2023

Package

npm randomatic (npm)

Affected versions

< 3.0.0

Patched versions

3.0.0

Description

Affected versions of randomatic generate random values using a cryptographically weak psuedo-random number generator. This may result in predictable values instead of random values as intended.

Recommendation

Update to version 3.0.0 or later.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Use of Insufficiently Random Values

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. Learn more on MITRE.

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

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