CVE-2020-1956 affects Apache Kylin versions 2.3.0 through 2.6.5 and 3.0.1. This vulnerability allows an attacker to perform OS command injection via certain RESTful APIs. Due to improper input validation, an attacker can execute arbitrary OS commands, resulting in severe security risks. The CVSS score for this vulnerability is 8.8, categorizing it as high severity.
Organizations using the affected versions of Apache Kylin should recognize the potential impact, which includes unauthorized command execution, leading to data breaches or system compromise. The exploitation of this vulnerability is particularly critical given its network attack vector and low attack complexity. Organizations must act to mitigate this risk.
Currently, this vulnerability is known to be actively exploited in the wild, and security teams should prioritize patching immediately. The urgency of addressing this issue cannot be overstated, as attackers may leverage this vulnerability to gain unauthorized access and control over systems.
Organizations must apply the relevant patches provided by Apache for Kylin to mitigate the risk associated with this vulnerability. Failure to address this could lead to severe implications for data security and user trust.
Vulnerability Details
The official description of CVE-2020-1956 states that it affects Apache Kylin versions 2.3.0, including releases up to 2.6.5 and 3.0.1, where certain RESTful APIs concatenate OS commands with user input without proper validation. This oversight allows a malicious user to execute arbitrary OS commands.
The CVSS score for this vulnerability is 8.8, indicating high severity due to its significant impact on confidentiality, integrity, and availability. The vulnerability is classified under CWE-78, which pertains to OS command injection.
Apache Kylin is the affected product, with the potential for significant impacts on organizations relying on this technology. The publication date of this vulnerability is May 22, 2020.
Technical Analysis
The primary root cause of CVE-2020-1956 is the failure to sanitize user input in several RESTful APIs, allowing an attacker to manipulate command execution. The attack vector is classified as network-based, meaning an attacker can exploit this vulnerability remotely, requiring only low privileges to initiate the attack.
The attack complexity is low, with no user interaction required. This vulnerability results in high confidentiality, integrity, and availability impacts, making it critical for organizations to assess their exposure and potential blast radius in case of exploitation.
Risk & Impact Analysis
The real-world risk posed by CVE-2020-1956 is significant. An attacker exploiting this vulnerability could gain control over affected systems, leading to data leaks, service interruptions, and extensive damage to organizational reputation and trust. The potential for a widespread impact emphasizes the need for immediate action.
Given the CVSS score of 8.8 and its classification under the Known Exploited Vulnerabilities (KEV) catalog, organizations are urged to address this vulnerability in their patch management cycles. The urgency of resolution is critical, as the longer it remains unpatched, the greater the risk of exploitation.
