CVE-2024-26331 in Server
Summary
by MITRE • 04/30/2024
ReCrystallize Server 5.10.0.0 uses a authorization mechanism that relies on the value of a cookie, but it does not bind the cookie value to a session ID. Attackers can easily modify the cookie value, within a browser or by implementing client-side code outside of a browser. Attackers can bypass the authentication mechanism by modifying the cookie to contain an expected value.

The vulnerability identified as CVE-2024-26331 affects ReCrystallize Server version 5.10.0.0 and represents a critical authentication bypass flaw that undermines the system's security posture. This issue stems from a fundamental weakness in the server's authorization mechanism where session management is improperly implemented. The server relies on cookie values for authentication purposes but fails to establish proper binding between these cookie values and actual session identifiers, creating a significant security gap that can be exploited by malicious actors.
The technical flaw manifests in the server's session handling architecture where cookie values are used as the sole means of authentication without proper session binding. This design flaw allows attackers to manipulate cookie values directly through browser developer tools or custom client-side code implementations. The absence of session ID binding means that any attacker who can observe or predict a valid cookie value can simply modify their local cookie to match the required authentication format. This weakness directly violates established security principles for session management and authentication mechanisms.
From an operational impact perspective, this vulnerability enables unauthorized access to protected resources and functionality within the ReCrystallize Server environment. Attackers can bypass authentication controls and potentially gain access to sensitive data, administrative functions, or system resources that should only be available to authenticated users. The ease of exploitation means that even relatively unsophisticated attackers can leverage this vulnerability to compromise the system's integrity and confidentiality. The impact extends beyond simple unauthorized access as it can potentially enable further attacks such as privilege escalation or data exfiltration.
The vulnerability aligns with CWE-384, which specifically addresses session management flaws where objects are used as session identifiers without proper binding to session IDs. This weakness also relates to ATT&CK technique T1078.004 which covers valid accounts through compromised credentials, as attackers can effectively bypass authentication mechanisms to obtain unauthorized access. The flaw represents a classic case of insufficient session binding where cookie values are treated as equivalent to session identifiers without proper cryptographic binding or validation mechanisms.
Effective mitigations for this vulnerability require immediate implementation of proper session management practices including binding cookie values to unique session identifiers, implementing cryptographic session tokens, and ensuring that session data cannot be manipulated by client-side code. The server should enforce server-side session validation where cookie values are verified against stored session data rather than relying solely on client-provided cookie values. Additionally, implementing secure session handling mechanisms that include proper session expiration, regeneration of session identifiers, and validation of session integrity through cryptographic means would address the core issue. Organizations should also consider implementing additional security controls such as rate limiting, monitoring for suspicious authentication patterns, and regular security assessments to detect and prevent exploitation of similar vulnerabilities.
