OrientDB Server Community Edition uses insufficiently random values to generate session IDs

Moderate severity GitHub Reviewed Published Oct 18, 2018 to the GitHub Advisory Database • Updated Sep 12, 2023

Package

maven com.orientechnologies:orientdb-server (Maven)

Affected versions

< 2.0.15
= 2.1.0

Patched versions

2.0.15
2.1.1

Description

OrientDB Server Community Edition before 2.0.15 and 2.1.x before 2.1.1 improperly relies on the java.util.Random class for generation of random Session ID values in the server/network/protocol/http/OHttpSessionManager.java, which makes it easier for remote attackers to predict a value by determining the internal state of the PRNG in this class.

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.
