CVE-2021-43780 affects the Redash package, a popular tool used for data visualization and sharing. This vulnerability allows advanced methods of Server Side Request Forgery (SSRF) in installations that enable URL-loading data sources such as JSON, CSV, or Excel. Due to its nature, the risk to organizations includes exposure to potentially sensitive data and unauthorized actions initiated via crafted requests.
This vulnerability has been classified as medium severity, with a CVSS score of 6.8. The implications are significant, as attackers can exploit this vulnerability to access internal services or sensitive data stored within the server environment. Organizations using affected versions should prioritize remediation efforts.
As of the publication date, users are advised to upgrade to version 10.0.1 or later to mitigate the risks associated with this vulnerability. Additionally, there are workarounds to disable vulnerable data sources. Given the nature of the vulnerability and its potential impact, organizations must act promptly to secure their installations.
Organizations should prioritize patching immediately. The affected versions include all Redash installations prior to 10.0.1, emphasizing the need for immediate action to secure user environments.
Vulnerability Details
The official description of CVE-2021-43780 indicates that the vulnerability is due to improper handling of URL-loading data sources, resulting in SSRF vulnerabilities. The relevant CVSS score from NVD is 8.8, indicating a high severity level, while the alternative CVSS score from GitHub reflects a medium severity.
The affected product is Redash, and the vendor is also Redash. The vulnerability was published on November 24, 2021, and it is classified under CWE-918, which pertains to Server Side Request Forgery.
Technical Analysis
The root cause of this vulnerability lies in the handling of HTTP requests within the Redash application. The attack vector is network-based, and the attack complexity is considered high due to the required conditions for exploitation. Privileges required for exploitation are low, meaning that an attacker may not need extensive access to initiate an attack. Additionally, user interaction is not required for exploitation.
The impacts on confidentiality and integrity are high, indicating that successful exploitation could lead to unauthorized access to sensitive information and potential modification of data. However, availability is not impacted, as the attacks do not disrupt service but rather exploit existing functionalities.
Risk & Impact Analysis
The risks associated with CVE-2021-43780 are significant for organizations utilizing Redash for data visualization. The potential for data exposure via SSRF attacks can lead to severe consequences, including unauthorized access to internal networks and sensitive information. The blast radius could extend beyond the Redash installation, affecting other interconnected systems.
Given the CVSS score of 6.8, organizations should address this vulnerability in their priority patch cycles. The exploitability of this vulnerability, though not currently known to be actively exploited, necessitates immediate attention to mitigate potential risks. The lack of public exploits further underscores the urgency for organizations to implement patches and workarounds.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Redash prior to 10.0.1 are affected by this vulnerability. Organizations should ensure that they upgrade to the latest version to mitigate the associated risks.
Mitigation & Remediation
Organizations should upgrade to version 10.0.1 of Redash to receive the necessary patch. In cases where an upgrade is not immediately possible, disabling the vulnerable data sources or switching them to 'View Only' mode for all groups can serve as temporary mitigations. Additionally, administrators may modify Redash's configuration through environment variables to enhance security.
For comprehensive security, organizations are encouraged to engage in penetration testing to identify and remediate similar vulnerabilities in their applications.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual HTTP requests that may indicate SSRF attempts. Behavioral anomalies and unauthorized data access patterns should also be flagged for further investigation.
AppSecure Threat Intelligence Insight
CVE-2021-43780 highlights the importance of securing data visualization platforms against SSRF vulnerabilities. The increasing trend in SSRF exploitation demands that organizations adopt robust security measures, including regular updates and effective monitoring strategies.
Security teams should familiarize themselves with best practices for penetration testing methodology and implement a comprehensive vulnerability management program to proactively address such vulnerabilities.
Adopting a continuous security posture, including routine assessments and timely patching, will enhance resilience against emerging threats.
