CVE-2024-7553: High Vulnerability in MongoDB Server

CVE-2024-7553 is a high-severity vulnerability that allows for local privilege escalation due to incorrect validation of files loaded from a local untrusted directory. This vulnerability specifically impacts MongoDB Server versions running on the Windows operating system. The affected versions include MongoDB Server v5.0 prior to 5.0.27, v6.0 prior to 6.0.16, v7.0 prior to 7.0.12, and v7.3 prior to 7.3.3. Additionally, the MongoDB C Driver versions prior to 1.26.2 and the MongoDB PHP Driver versions prior to 1.18.1 are also impacted.

The potential risk to organizations includes executing arbitrary behavior determined by the contents of untrusted files. Given the nature of this vulnerability and its high CVSS score of 7.3, organizations must act swiftly to address this issue.

There is currently no public exploit confirmed for this vulnerability, but the exploitability status is marked as high. Therefore, organizations should prioritize patching immediately.

Organizations using the affected versions should refer to their respective vendor advisories for patch details to mitigate the risks associated with this vulnerability.

Vulnerability Details

The official description states that incorrect validation of files loaded from a local untrusted directory may allow local privilege escalation if the underlying operating system is Windows. This may result in the application executing arbitrary behavior determined by the contents of untrusted files.

The CVSS score for this vulnerability is 7.3, indicating it falls within the high severity category. The base severity is categorized as high, and the attack vector is local with low complexity, requiring low privileges and user interaction.

The affected products include MongoDB Server, MongoDB C Driver, and MongoDB PHP Driver. The vulnerability was reported on August 7, 2024.

Technical Analysis

The root cause of CVE-2024-7553 is attributed to the incorrect validation of files from untrusted directories. Attackers may leverage this vulnerability by placing malicious files in a directory that the application accesses, leading to potential privilege escalation.

The attack vector is local, which means that the attacker must have access to the machine where MongoDB is installed. The attack complexity is low, as it does not require specialized skills or knowledge to exploit, and the attacker needs low privileges to execute the exploit.

User interaction is required in this attack scenario, as the malicious file needs to be executed by a user who has access to the MongoDB instance. The impacts on confidentiality, integrity, and availability are all high, as the exploitation could allow unauthorized access to sensitive information, modification of data, and disruption of service.

Risk & Impact Analysis

The real-world risk associated with CVE-2024-7553 is significant, especially for organizations that rely heavily on MongoDB for their operations. The potential for an attacker to execute arbitrary code can lead to unauthorized access to sensitive data and further exploitation of the system.

Given the high CVSS score and the exploitation potential, this vulnerability warrants immediate attention. Organizations should assess their deployment configurations and ensure that they are not exposing themselves to unnecessary risks.

The urgency for remediation is high, and organizations should prioritize patching this vulnerability to minimize the risk of exploitation. Affected environments on Windows should be treated with particular attention as they are the only ones impacted by this issue.

Exploitation Status

Affected Versions

The affected versions of MongoDB and its drivers include:

- MongoDB Server v5.0 versions prior to 5.0.27 - MongoDB Server v6.0 versions prior to 6.0.16 - MongoDB Server v7.0 versions prior to 7.0.12 - MongoDB Server v7.3 versions prior to 7.3.3 - MongoDB C Driver versions prior to 1.26.2 - MongoDB PHP Driver versions prior to 1.18.1

Mitigation & Remediation

To mitigate the risks associated with this vulnerability, organizations should apply the following measures:

1. **Patch**: Upgrade MongoDB Server and its drivers to the latest versions to ensure vulnerabilities are patched. For MongoDB Server, upgrade to versions 5.0.27, 6.0.16, 7.0.12, or 7.3.3 and for drivers to 1.26.2 (C Driver) and 1.18.1 (PHP Driver). 2. **Configuration Hardening**: Review and secure configurations, ensuring that untrusted directories are not accessible to the MongoDB service. 3. **Monitoring**: Implement monitoring for unusual file access patterns that may indicate exploitation attempts.

4. Engage with security experts for penetration testing to assess the environment against such vulnerabilities.

Detection Guidance

Organizations should monitor the following indicators to detect possible exploitation of CVE-2024-7553:

1. Log indicators of file access to untrusted directories. 2. Watch for behavioral anomalies in application interactions with files. 3. Network signatures that indicate unusual traffic patterns associated with the MongoDB service.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2024-7553 lies in its potential to expose sensitive data and disrupt business operations. It reflects a pattern of vulnerabilities where applications improperly handle file validations, emphasizing the need for robust security practices.

This vulnerability serves as a crucial lesson for security teams to prioritize secure coding practices, especially in environments using dynamic file handling. The strategic takeaway is that organizations must implement comprehensive security assessments and adhere to best practices to prevent similar vulnerabilities.

Engaging in regular penetration testing can help identify such weaknesses before they can be exploited.

Additionally, building a robust vulnerability management program is essential in continuously monitoring and addressing security gaps.

Lastly, adopting best practices for API security will further strengthen defenses against such vulnerabilities.
