CVE-2014-3120 is a high-severity vulnerability affecting Elasticsearch versions prior to 1.2. The default configuration enables dynamic scripting, allowing remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search. This vulnerability compromises the security of the system significantly, especially if Elasticsearch is not isolated within its own virtual machine. Organizations running affected versions must recognize the urgency of this vulnerability due to its potential for exploitation.
The CVSS v3.1 score for this vulnerability is 8.1, indicating high severity. The attack vector is classified as network-based with low complexity and requires minimal privileges, making it accessible to various threat actors. The potential impacts include high confidentiality and integrity risks, as attackers could manipulate data and execute malicious scripts.
Given the nature of this vulnerability, organizations should prioritize patching immediately. The addition of this vulnerability to the Known Exploited Vulnerabilities (KEV) catalog underscores its active exploitation in the wild, further emphasizing the need for prompt remediation.
This vulnerability allows attackers to breach systems and potentially gain unauthorized access to sensitive information, thus posing a significant risk to organizations utilizing Elasticsearch. Proper configuration and isolation of Elasticsearch instances are essential to mitigate this risk.
Vulnerability Details
The official description of CVE-2014-3120 states: 'The default configuration in Elasticsearch before 1.2 enables dynamic scripting, which allows remote attackers to execute arbitrary MVEL expressions and Java code via the source parameter to _search.' This vulnerability is classified under CWE-284, indicating improper access control.
The CVSS score of 8.1 reflects the serious nature of this vulnerability. It is crucial for organizations using Elasticsearch to evaluate their current configurations and determine if they are running affected versions. The publication date of this vulnerability is July 28, 2014.
Technical Analysis
The root cause of CVE-2014-3120 lies in the default configuration of Elasticsearch, which enables dynamic scripting. This configuration flaw allows attackers to craft requests that execute arbitrary code, manipulating the Elasticsearch server without proper authorization. The attack vector is network-based, meaning attackers do not need physical access to the server to exploit this vulnerability.
The attack complexity is low, and the privileges required to execute a successful attack are also low, making this vulnerability particularly concerning. User interaction is not required, allowing attackers to exploit it remotely. The impacts on confidentiality and integrity are high, as attackers can gain access to sensitive data and modify it at will.
Risk & Impact Analysis
Real-world deployment of Elasticsearch with the default configuration poses significant risks. Attackers may leverage this vulnerability to execute arbitrary code, leading to unauthorized access and potential data breaches. The blast radius is considerable, as many organizations utilize Elasticsearch in critical applications.
Given the CVSS score of 8.1 and its inclusion in the KEV catalog, organizations must assess the urgency of addressing this vulnerability. It represents a clear threat to confidentiality and integrity, necessitating immediate attention and remediation efforts to protect sensitive data.
