CVE-2015-2913 in Server Community Edition
Summary
by MITRE
server/network/protocol/http/OHttpSessionManager.java in the Studio component in 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, which makes it easier for remote attackers to predict a value by determining the internal state of the PRNG in this class.

The vulnerability identified as CVE-2015-2913 affects the OrientDB Server Community Edition, specifically within the Studio component's session management mechanism. This issue stems from the improper use of the java.util.Random class for generating session identifiers, creating a significant security weakness that exposes the system to predictable session hijacking attacks. The vulnerability exists in versions prior to 2.0.15 and 2.1.1, making a substantial portion of the OrientDB community edition susceptible to exploitation.
The technical flaw lies in the reliance on java.util.Random for session ID generation, which represents a fundamental cryptographic weakness in session management. The java.util.Random class is not cryptographically secure and uses a linear congruential generator algorithm that can be reverse-engineered to predict future values when sufficient samples are collected. This weakness directly violates security best practices outlined in the OWASP Secure Coding Standards and aligns with CWE-330, which specifically addresses the use of insecure random number generators in cryptographic contexts. The predictable nature of session IDs created through this mechanism allows attackers to forge valid session tokens without requiring authentication credentials.
The operational impact of this vulnerability is severe as it enables remote attackers to perform session hijacking attacks with minimal effort. An attacker who can predict session IDs can impersonate legitimate users and gain unauthorized access to database resources, potentially leading to data breaches, unauthorized data modification, or complete system compromise. This vulnerability particularly affects web-based database management interfaces where session management is critical for maintaining user authentication state. The attack vector is remote and requires no special privileges, making it highly exploitable in environments where OrientDB is exposed to untrusted networks.
The attack surface is further expanded by the fact that this vulnerability affects the Studio component, which is typically accessible through standard HTTP interfaces, making it particularly dangerous in production environments. According to ATT&CK framework, this vulnerability maps to T1190 - Exploit Public-Facing Application, where attackers can leverage predictable session identifiers to gain unauthorized access. The vulnerability also relates to T1078 - Valid Accounts, as successful exploitation allows attackers to assume legitimate user identities. Organizations using OrientDB in their infrastructure should prioritize immediate patching to address this vulnerability, as the predictable session IDs can be exploited within minutes of initial reconnaissance. The remediation process requires updating to versions 2.0.15 or 2.1.1, which implement proper cryptographically secure random number generation for session identifier creation, ensuring that session tokens cannot be predicted by attackers with knowledge of the system's internal state.
