NocoDB is software for building databases as spreadsheets. A medium-severity blind Server-Side Request Forgery (SSRF) vulnerability exists in the `uploadViaURL` functionality due to an unprotected `HEAD` request. While the subsequent file retrieval logic correctly enforces SSRF protections, the initial metadata request executes without validation. This allows limited outbound requests to arbitrary URLs before SSRF controls are applied. Organizations should prioritize patching immediately.
This vulnerability is significant because it can enable an attacker to exploit network resources, potentially leading to data exfiltration or unauthorized access. The vulnerability has been assigned a CVSS score of 4.9, indicating that it is of medium severity, and organizations should address this in their priority patch cycle.
Version 0.301.0 of NocoDB contains a patch for this issue. Organizations running versions prior to this should take immediate action to mitigate the risk associated with this vulnerability.
No public exploit has been identified for this vulnerability at this time, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog, which suggests that while the risk is present, it may not currently be actively exploited in the wild.
Organizations should follow best practices for vulnerability management and plan for timely updates to their software to protect against potential exploitation.
Vulnerability Details
NocoDB, a tool designed for database management, has been found to have a blind SSRF vulnerability in its `uploadViaURL` functionality. This flaw is present in versions prior to 0.301.0, where an unprotected `HEAD` request allows for potentially harmful outbound requests before SSRF protections are enforced. The CVSS score for this vulnerability is 4.9, categorizing it as medium severity. The specific CWE associated with this vulnerability is CWE-918.
Technical Analysis
The root cause of this vulnerability lies in the handling of the `HEAD` request within the `uploadViaURL` functionality. The initial metadata request is executed without proper validation, allowing attackers to make limited outbound requests to arbitrary URLs. The attack vector for this vulnerability is the network, and it has a high attack complexity due to the need for low privileges and no user interaction.
The confidentiality and integrity impacts are assessed as low, with no availability impact reported. Organizations should be aware of the potential risks associated with this vulnerability and implement necessary controls to mitigate such issues.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is moderate, given the potential for limited outbound requests to arbitrary URLs. Organizations using NocoDB should recognize that while this vulnerability does not currently have known exploits, the risk to organizations includes the possibility of unauthorized access to sensitive information or network resources. The urgency for remediation is high, and organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of NocoDB include all versions prior to 0.301.0. Organizations running these versions must update to the latest version to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to NocoDB version 0.301.0 or later. If immediate patching is not possible, organizations should consider implementing network controls to restrict outbound requests and monitor for any unusual activity. Additionally, an effective vulnerability management program can help in identifying and addressing such vulnerabilities proactively.
Detection Guidance
Organizations should monitor their network traffic for unusual outbound requests originating from NocoDB instances. Log indicators should include unexpected `HEAD` requests to arbitrary URLs. Behavioral anomalies, such as unusual patterns in data uploads or retrievals, should also be investigated.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in the potential to expose network resources to unauthorized access. It highlights the importance of proper request validation in web applications, particularly in functionalities that interact with external URLs. Security teams should take note of this vulnerability to enhance their application security posture and consider adopting practices for continuous security testing and monitoring.
Organizations can enhance their security by adopting a comprehensive approach that includes both proactive and reactive measures. For more information on effective security strategies, organizations can consult resources on penetration testing and vulnerability management.
Through continuous engagement in security practices, organizations can better defend against similar vulnerabilities in the future.
