Adobe ColdFusion versions 2018 Update 15 (and earlier) and 2021 Update 5 (and earlier) are affected by an Improper Access Control vulnerability that could result in arbitrary code execution in the context of the current user. This vulnerability allows attackers to execute code without requiring user interaction, which significantly increases the risk of exploitation.
The vulnerability has been classified with a CVSS score of 8.6, indicating a high severity level. The attack vector is over the network, and the complexity is low, meaning that attackers can exploit this vulnerability easily. Given the potential for arbitrary code execution, organizations must treat this vulnerability with urgency.
Risk to organizations includes unauthorized access to sensitive data and potential compromise of the entire system. Adobe has acknowledged this vulnerability and has provided patches to address the issue. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
As of now, there are reports of known exploits in the wild, further emphasizing the need for urgent remediation. Organizations that use affected versions of ColdFusion must take action quickly to protect themselves from potential attacks.
Vulnerability Details
The vulnerability is characterized as Improper Access Control, categorized under CWE-284. The official description states that exploitation does not require user interaction, and the affected versions are Adobe ColdFusion 2018 Update 15 and earlier, and 2021 Update 5 and earlier.
The CVSS version 3.1 vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N, indicating that the attack vector is network-based, with low complexity and no privileges required for exploitation. The confidentiality impact is rated high, while integrity and availability impacts are rated none.
Technical Analysis
The root cause of this vulnerability is related to improper access control mechanisms within Adobe ColdFusion, which may allow unauthorized users to execute arbitrary code. The attack vector is primarily network-based, which means that an attacker can exploit this vulnerability remotely without any physical access.
The attack complexity is low, and no user interaction is required, making it easier for attackers to exploit this vulnerability. The lack of required privileges means that even low-level users can potentially execute code.
Risk & Impact Analysis
Real-world deployment risk is significant due to the potential for arbitrary code execution. Attackers may leverage this vulnerability to gain unauthorized access and control over systems, leading to data breaches or system compromises. The blast radius for this vulnerability can be extensive, especially for organizations with multiple deployments of ColdFusion.
Given its classification in the KEV catalog, organizations should address this vulnerability in their priority patch cycle. The urgency is high, as the risk of exploitation is elevated due to the presence of known exploits.
