CVE-2024-7783 in anything-llm
Summary
by MITRE • 10/29/2024
mintplex-labs/anything-llm version latest contains a vulnerability where sensitive information, specifically a password, is improperly stored within a JWT (JSON Web Token) used as a bearer token in single user mode. When decoded, the JWT reveals the password in plaintext. This improper storage of sensitive information poses significant security risks, as an attacker who gains access to the JWT can easily decode it and retrieve the password. The issue is fixed in version 1.0.3.

The vulnerability identified as CVE-2024-7783 affects the mintplex-labs/anything-llm application in its latest version, presenting a critical security flaw in how authentication tokens are managed within single user mode operations. This issue represents a fundamental failure in secure token design and sensitive data handling practices, where the application stores authentication credentials directly within JSON Web Tokens rather than utilizing proper token-based authentication mechanisms. The flaw manifests when the system generates a JWT bearer token that contains plaintext password information, creating an exploitable condition that undermines the entire authentication framework. This vulnerability directly violates security best practices and represents a significant deviation from established protocols for token-based authentication systems.
The technical implementation of this vulnerability stems from the improper encoding of sensitive information within the JWT payload itself, rather than relying on secure token mechanisms that would typically utilize session identifiers or cryptographic keys. When an attacker gains access to the JWT through various attack vectors such as network interception, insecure storage, or application-level vulnerabilities, they can easily decode the token using standard JWT decoding libraries and extract the plaintext password. This approach completely eliminates the security benefits that JWTs are designed to provide, transforming what should be a secure authentication mechanism into a transparent storage container for sensitive credentials. The vulnerability operates at the application layer and can be exploited through multiple attack paths including man-in-the-middle attacks, insecure client-side storage, or compromised application environments, making it particularly dangerous in real-world deployment scenarios.
The operational impact of this vulnerability extends far beyond simple credential exposure, as it fundamentally compromises the security posture of any system utilizing the affected application version. An attacker who successfully obtains a valid JWT can immediately gain unauthorized access to user accounts and system resources without the need for additional attack vectors or credential cracking techniques. This vulnerability enables privilege escalation attacks, lateral movement within networks, and persistent access to sensitive data, creating a significant risk for organizations that rely on the application for critical operations. The exposure of plaintext passwords within JWTs also means that even if other security controls are in place, such as network segmentation or access controls, the authentication layer becomes completely compromised, rendering these additional defenses ineffective. The vulnerability affects single user mode deployments specifically, but this limitation does not reduce the severity of the impact, as it still provides complete unauthorized access to the system's authenticated state.
Mitigation strategies for CVE-2024-7783 require immediate action to upgrade to version 1.0.3, which addresses the core issue by implementing proper token design practices that separate authentication credentials from token contents. Organizations should also implement comprehensive token lifecycle management, including secure generation, storage, and invalidation procedures that prevent the storage of sensitive information within tokens. Security teams must conduct thorough audits of token usage patterns and implement monitoring systems to detect unauthorized token access attempts. Additional defensive measures include implementing proper access controls, regular security assessments, and ensuring that all authentication mechanisms follow established security standards such as those outlined in the OWASP Authentication Cheat Sheet. The vulnerability also highlights the importance of secure coding practices and regular security testing, particularly for applications that handle sensitive authentication data. Organizations should consider implementing additional layers of security such as multi-factor authentication, token binding, and secure key management systems to reduce the impact of similar vulnerabilities in the future. This issue serves as a critical reminder of the importance of following established security frameworks and avoiding common pitfalls in token-based authentication design that can lead to catastrophic security failures.
