CVE-2017-12149 is a critical vulnerability affecting the Red Hat JBoss Application Server as shipped with Red Hat Enterprise Application Platform 5.2. The vulnerability arises from the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker, which fails to restrict the classes for which it performs deserialization. This oversight allows an attacker to execute arbitrary code via crafted serialized data. With a CVSS score of 9.8, this vulnerability represents a significant risk to organizations.
Risk to organizations includes potential unauthorized access to sensitive data and disruption of service. Given the nature of the vulnerability, it can be exploited remotely without requiring user interaction, making it a high-priority issue for security teams. Organizations should prioritize patching immediately to mitigate the associated risks.
Currently, this vulnerability is known to be actively exploited, and there are public proof-of-concept (PoC) exploits available. In addition, it has been included in the Known Exploited Vulnerabilities (KEV) catalog, emphasizing its critical nature and the urgency for affected organizations to take immediate action.
Organizations using Red Hat JBoss Application Platform 5.2 or earlier versions must assess their exposure to CVE-2017-12149 and implement the necessary updates as soon as possible.
Vulnerability Details
The official description outlines that the vulnerability allows arbitrary code execution due to unrestricted deserialization in the JBoss Application Server. This vulnerability is classified as a critical issue with a CVSS score of 9.8 based on the CVSS version 3.1. It impacts confidentiality, integrity, and availability, making it a significant threat to organizational security.
Technical Analysis
The root cause of CVE-2017-12149 is the failure to properly restrict classes during the deserialization process within the ReadOnlyAccessFilter. This vulnerability can be exploited over the network, requiring low attack complexity and no privileges or user interaction. The high impact on confidentiality, integrity, and availability indicates that successful exploitation could lead to severe consequences for affected organizations.
Risk & Impact Analysis
The risk to organizations includes potential unauthorized access to sensitive data, system compromise, and service disruption. The blast radius of this vulnerability extends to any environment utilizing the affected versions of Red Hat JBoss Application Server, making it critical for organizations to act promptly. Given its inclusion in the KEV catalog, organizations should address this vulnerability in their priority patch cycle.
