Vulnerability Details
As defined by the official CVE description, Adobe ColdFusion versions 2018 Update 15 (and earlier) and 2021 Update 5 (and earlier) are susceptible to a Deserialization of Untrusted Data vulnerability. This vulnerability allows attackers to execute arbitrary code within the context of the current user without requiring any form of user interaction.
The CVSS score for this vulnerability is 9.8, indicating a critical severity. The attack vector is classified as NETWORK with low complexity, meaning that attackers can exploit this vulnerability remotely and with minimal effort. No privileges are required for exploitation, making it more dangerous.
The vulnerability falls under the Common Weakness Enumeration (CWE) classification CWE-502, which refers to issues related to deserialization of untrusted data.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of untrusted data during the deserialization process. Attackers may leverage this flaw to send crafted data that the application deserializes, leading to arbitrary code execution.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability without needing physical access to the affected systems. The attack complexity is low, and no user interaction is required, which increases the risk of exploitation.
The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation could lead to unauthorized data access, modification, and service disruptions.
Risk & Impact Analysis
Real-world deployment of affected Adobe ColdFusion versions presents significant risks due to the potential for unauthorized code execution. Given the critical severity of this vulnerability, organizations are at heightened risk of being targeted by attackers who can exploit this flaw to gain control over systems.
This vulnerability emphasizes the need for organizations to maintain robust application security practices. With the potential for widespread impact, the urgency for remediation is critical. Organizations should address this vulnerability as a priority in their patch management cycle.
In addition to patching, organizations should evaluate their overall security posture, including conducting vulnerability assessments and penetration testing to identify and remediate similar weaknesses.
