CVE-2024-6037 is a vulnerability identified in the gaizhenbiao/chuanhuchatgpt software, specifically in version 20240410, where the application improperly handles resource allocation by allowing attackers to create arbitrary directories anywhere on the server filesystem, including the root directory (e.g., C: drive). This vulnerability is categorized under CWE-770, which involves allocation of resources without proper limits or throttling. The flaw enables an unauthenticated attacker to remotely exploit the system without any user interaction or privileges, by sending crafted requests that trigger folder creation at arbitrary paths. This uncontrolled folder creation can lead to excessive consumption of disk space and other system resources, potentially resulting in resource exhaustion. The consequences include denial of service (DoS) due to server unavailability, and risks of data loss or corruption if critical system or application files are affected. The CVSS v3.0 base score is 7.5, reflecting high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), but high impact on availability (A:H). Currently, there are no patches publicly available, nor known exploits in the wild, but the vulnerability's characteristics make it a significant threat if weaponized. Organizations using this software should be aware of the risk and prepare to implement mitigations or patches once released.

For European organizations, the impact of CVE-2024-6037 can be substantial, particularly for those relying on gaizhenbiao/chuanhuchatgpt in production environments. The ability for an unauthenticated attacker to create arbitrary folders anywhere on the server can lead to rapid resource exhaustion, causing denial of service and operational disruptions. This can affect availability of critical services, leading to downtime and potential financial losses. Additionally, if folder creation interferes with system or application files, data corruption or loss may occur, impacting data integrity and business continuity. Sectors such as finance, healthcare, and public administration, which require high availability and data integrity, could face severe consequences. The lack of required privileges or user interaction lowers the barrier for exploitation, increasing the risk of automated attacks. European organizations with limited visibility into filesystem changes or lacking strict access controls may be particularly vulnerable. Furthermore, the potential for cascading failures in interconnected systems raises concerns for critical infrastructure and cloud service providers within Europe.

To mitigate CVE-2024-6037 effectively, European organizations should implement several targeted measures beyond generic advice: 1) Immediately restrict network access to the gaizhenbiao/chuanhuchatgpt service to trusted IP ranges and internal networks to reduce exposure. 2) Employ strict filesystem permissions and access controls to prevent unauthorized folder creation, especially restricting write permissions on critical directories such as the root or system folders. 3) Monitor filesystem activity for unusual or unauthorized directory creation using host-based intrusion detection systems (HIDS) or file integrity monitoring tools. 4) Implement resource usage monitoring and alerting to detect abnormal disk space consumption or inode exhaustion early. 5) If possible, deploy application-layer firewalls or reverse proxies to filter and validate incoming requests to the vulnerable service, blocking suspicious payloads that attempt directory creation. 6) Engage with the vendor or community to obtain patches or updates addressing this vulnerability and plan for rapid deployment once available. 7) Conduct regular security audits and penetration testing focusing on filesystem permissions and resource allocation controls in the affected environment. 8) Educate system administrators and security teams about this vulnerability to ensure prompt detection and response. These steps, combined, will reduce the attack surface and limit the potential damage from exploitation.
