CVE-2006-4048 in Netious CMS
Summary
by MITRE
Netious CMS 0.4 initializes session IDs based on the client IP address, which allows remote attackers to gain access to the administration section when originating from the same IP address as the administrator. NOTE: the provenance of this information is unknown; the details are obtained from third party information.

This vulnerability exists in Netious CMS version 0.4 where the session management implementation suffers from a critical flaw in how session identifiers are generated. The system initializes session IDs by incorporating the client IP address as a component in the session token creation process, creating a predictable session identifier pattern that can be exploited by malicious actors. This design flaw fundamentally undermines the security of the authentication mechanism by eliminating the randomness that is essential for secure session management. The vulnerability creates a scenario where an attacker who can determine or predict the administrator's IP address can potentially forge session tokens and gain unauthorized administrative access to the CMS system.
The technical implementation of this vulnerability stems from a weak session generation algorithm that directly ties session identifiers to network layer information rather than employing cryptographically secure random number generation. This approach violates fundamental security principles outlined in the OWASP Top Ten and CWE-310, which specifically addresses cryptographic weaknesses in session management. When the administrator logs into the system from a specific IP address, the session ID becomes predictable based on that IP address, making it susceptible to session hijacking attacks. The vulnerability is particularly dangerous because it eliminates the need for brute force attacks or other complex exploitation techniques, as the session token generation becomes deterministic based on IP address information.
From an operational perspective, this vulnerability creates a significant risk for organizations using Netious CMS 0.4, as it allows remote attackers to bypass authentication mechanisms simply by originating from the same IP address as an authenticated administrator. The attack vector is particularly concerning because it does not require sophisticated techniques or extensive reconnaissance, making it accessible to attackers with basic network knowledge. The impact extends beyond simple unauthorized access, potentially allowing attackers to modify content, add malicious users, or compromise the entire CMS infrastructure. This vulnerability represents a classic case of insufficient entropy in session management, which is categorized under the MITRE ATT&CK framework as a privilege escalation technique through session management flaws. The vulnerability also aligns with CWE-287, which deals with improper authentication, and CWE-306, which addresses missing authentication.
The mitigation strategies for this vulnerability must address the fundamental flaw in session ID generation while maintaining system functionality. Organizations should immediately upgrade to a newer version of Netious CMS that implements proper cryptographic session management with random session identifiers that are not derived from predictable network information. The implementation should utilize cryptographically secure random number generators to ensure that session tokens are unpredictable and cannot be easily guessed or reconstructed. Additionally, organizations should implement additional security controls such as IP address monitoring, rate limiting, and multi-factor authentication to provide defense-in-depth measures. The solution must ensure that session identifiers are generated using strong entropy sources and are independent of client network information to prevent the type of exploitation described in this vulnerability. Security teams should also consider implementing network segmentation and monitoring to detect unusual session activity patterns that might indicate exploitation attempts.
