What is CVE-2017-3066?

CVE-2017-3066 is a critical vulnerability found in Adobe ColdFusion, a widely used web application development framework. This vulnerability arises from a flaw in the Apache BlazeDS library that supports the serialization and deserialization of data. The flaw can be exploited by attackers to execute arbitrary code on affected systems. Given that ColdFusion is often employed for creating dynamic web applications, any successful exploitation could lead to severe repercussions for organizations, such as unauthorized access to sensitive data or disruption of business operations.

Technical Details

The vulnerability specifically affects Adobe ColdFusion versions 2016 Update 3 and earlier, ColdFusion 11 update 11 and earlier, and ColdFusion 10 Update 22 and earlier. It stems from improper handling of Java deserialization processes within the Apache BlazeDS library. When attackers send specially crafted serialized objects to an application that uses vulnerable versions of ColdFusion, they can potentially execute arbitrary code on the server, compromising the system’s integrity.

Potential Impact of CVE-2017-3066

Arbitrary Code Execution: The most significant impact of this vulnerability is the potential for attackers to execute arbitrary code on the server. This means malicious actors can gain control over the server, allowing them to steal data, manipulate application behavior, or deploy further exploits.
Data Breaches: Exploitation of this vulnerability can lead to unauthorized access to sensitive information stored within the ColdFusion applications. This poses a substantial risk of data breaches that can affect both organizations and their clients, with potential legal and reputational consequences.
Service Disruption: Successful attacks exploiting this vulnerability could also result in service disruptions. Compromised systems may be rendered unavailable, leading to downtime that can affect business operations and result in financial losses.

CISA Reported

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
