The Accoria Web Server, also known as the Rock Web Server version 1.4.7, contains a critical security flaw that compromises session integrity through predictable session identifier generation. This vulnerability specifically affects the httpmod-sessionid cookie implementation which generates session identifiers using a predictable algorithm rather than a cryptographically secure random number generator. The predictable nature of these session identifiers creates a significant attack surface that allows remote adversaries to perform session hijacking attacks with minimal effort and computational resources.
This vulnerability directly relates to CWE-330, which addresses the use of insufficiently random values in security contexts, and aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links. The flaw stems from the server's inability to generate cryptographically strong session identifiers, making it possible for attackers to guess valid session tokens through brute force or pattern analysis. The predictable session ID generation essentially provides attackers with a roadmap to compromise user sessions without requiring complex exploitation techniques or significant computational overhead.
The operational impact of this vulnerability extends beyond simple session hijacking to potentially enable complete account compromise and unauthorized access to protected resources. When attackers can predict session identifiers, they gain the ability to impersonate legitimate users and access sensitive data, perform unauthorized transactions, or execute administrative functions within the application. The vulnerability affects all users of the affected web server version, regardless of their authentication status or the security measures implemented at higher application layers, making it a systemic risk that can undermine entire web applications built on this platform.
Mitigation strategies should focus on immediate implementation of cryptographically secure session identifier generation mechanisms. Organizations should upgrade to a newer version of the Accoria Web Server that implements proper random session ID generation or apply patches that address the predictable cookie generation issue. Additionally, implementing additional security controls such as secure cookie flags, HTTP-only attributes, and session timeout mechanisms can help reduce the attack window. Network-level protections including intrusion detection systems and monitoring for suspicious session-related activities should also be deployed. The vulnerability demonstrates the critical importance of proper random number generation in security-sensitive contexts and highlights the need for regular security assessments of web server configurations to identify similar weaknesses in session management implementations.
