CVE-2022-45462 is a critical command injection vulnerability affecting Apache DolphinScheduler. This vulnerability allows attackers to execute arbitrary commands on the server when specific commands are configured. The issue is restricted to logged-in users, which adds a layer of complexity to its exploitation. With a CVSS score of 9.8, organizations should recognize the severity of this vulnerability and act quickly to secure their systems.
The risk to organizations includes potential unauthorized access and manipulation of sensitive data, which can lead to major operational disruptions. Given the nature of the vulnerability and its high severity rating, it is critical for organizations to prioritize patching immediately to version 2.0.6 or higher as a mitigating measure.
Currently, no public exploits are confirmed, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for exploitation remains high, and organizations should remain vigilant.
In summary, the combination of the critical nature of this vulnerability and the potential risks associated with it necessitates immediate action from all organizations using Apache DolphinScheduler.
Vulnerability Details
The official description of this vulnerability states: "Alarm instance management has command injection when there is a specific command configured. It is only for logged-in users. We recommend you upgrade to version 2.0.6 or higher." This vulnerability falls under the category of command injection, classified as CWE-77.
The vulnerability has a CVSS score of 9.8, indicating that it is critical. This score reflects a low attack complexity, no privileges required, and no user interaction necessary, making it particularly dangerous. Confidentiality, integrity, and availability impacts are all rated as high.
The affected product is Apache DolphinScheduler, specifically all versions prior to 2.0.6. The vulnerability was published on November 23, 2022.
Technical Analysis
The root cause of CVE-2022-45462 lies in how command instances are managed within the application. Specifically, the flaw allows attackers to inject commands due to improper validation of user input. This vulnerability can be exploited over the network, allowing a remote attacker to execute commands without needing to authenticate as a privileged user.
The attack complexity is low, as no special conditions are required for successful exploitation. Attackers do not need any privileges or user interaction, which significantly raises the risk factor. Additionally, the impact of successful exploitation is severe, affecting confidentiality, integrity, and availability.
Risk & Impact Analysis
The real-world risk associated with this vulnerability can be substantial. Organizations deploying Apache DolphinScheduler may find themselves at risk of unauthorized command execution, leading to data breaches or service disruptions. The potential blast radius is considerable, as the vulnerability affects all users who are logged in and have access to the command management feature.
Given the CVSS score of 9.8, organizations should address this vulnerability in their priority patch cycle. The urgency is underscored by the high percentile ranking of the EPSS score of approximately 95.7, indicating a significant likelihood of exploitation.
