CVE-2023-50164 is a critical vulnerability affecting Apache Struts, a widely used framework for building Java web applications. This vulnerability allows attackers to manipulate file upload parameters, enabling path traversal, which can lead to the unauthorized upload of malicious files. Such malicious files can be exploited to perform Remote Code Execution (RCE). With a CVSS score of 9.8, this vulnerability poses a severe risk to organizations relying on affected versions of Struts.
The exploitation of this vulnerability can have dire consequences, including unauthorized access to sensitive data and full control over affected systems. Organizations utilizing Apache Struts should prioritize patching this vulnerability immediately to mitigate potential attacks.
Users are strongly advised to upgrade to Struts versions 2.5.33 or 6.3.0.2 or greater to address this issue. The critical nature of this vulnerability necessitates a prompt response to ensure the security of systems.
Currently, there are known exploits, making it imperative for organizations to take immediate action to secure their applications.
Vulnerability Details
The vulnerability, identified as CVE-2023-50164, was published on December 7, 2023. It affects Apache Struts, specifically versions prior to 2.5.33 and 6.3.0.2. The vulnerability is classified as a critical remote code execution issue, where attackers can exploit path traversal vulnerabilities to upload malicious files.
The CVSS score of 9.8 indicates a high severity, with impacts on confidentiality, integrity, and availability marked as high. The underlying weakness is classified under CWE-552.
Technical Analysis
The root cause of this vulnerability lies in the way Apache Struts processes file uploads. Attackers can manipulate the parameters of file uploads, leveraging path traversal techniques to gain unauthorized access to the filesystem. The attack vector is network-based, with a low attack complexity and no privileges required, meaning that an attacker can exploit this vulnerability without needing special access to the system.
User interaction is not required, which further increases the risk. The impact on confidentiality, integrity, and availability is high, as successful exploitation can lead to complete system compromise.
Risk & Impact Analysis
Risk to organizations includes unauthorized control over web applications, data breaches, and potential system outages. Given that this vulnerability is actively exploited, organizations should prioritize patching immediately. The high CVSS score and the fact that this vulnerability has been included in various threat intelligence reports necessitate a thorough risk assessment for affected systems.
Organizations using versions of Struts prior to the recommended updates are at significant risk. The blast radius extends to any application relying on the affected framework, making it critical to address this vulnerability promptly.
