CVE-2023-29300 is a critical vulnerability found in Adobe ColdFusion, specifically impacting versions 2018u16 and earlier, 2021u6 and earlier, and 2023.0.0.330468 and earlier. This vulnerability allows for arbitrary code execution due to a deserialization of untrusted data. Notably, exploitation of this vulnerability does not require user interaction, which significantly increases the risk to organizations using affected versions.
With a CVSS score of 9.8, this vulnerability is classified as critical. The potential for exploitation is high, as attackers may leverage this vulnerability to execute arbitrary code on impacted systems. Organizations utilizing Adobe ColdFusion should prioritize patching to mitigate the risks associated with this vulnerability.
Risk to organizations includes unauthorized access and control over affected systems, leading to data breaches or service outages. Given the critical nature of this vulnerability, organizations should prioritize patching immediately.
As of the latest intelligence, there are no known public exploits or proof-of-concept (PoC) code available for this vulnerability. However, it is included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that it has been recognized as being actively exploited in the wild.
Organizations should take immediate action to secure their systems against this vulnerability by applying patches or implementing necessary mitigations.
Vulnerability Details
Adobe ColdFusion versions 2018u16 (and earlier), 2021u6 (and earlier), and 2023.0.0.330468 (and earlier) are affected by a deserialization of untrusted data vulnerability that could result in arbitrary code execution. The CVSS score is 9.8, indicating a critical severity level.
The CWE classification for this vulnerability is CWE-502, which correlates to deserialization of untrusted data. It is crucial for organizations to understand the implications of this vulnerability, as it can lead to significant security breaches.
Technical Analysis
The root cause of this vulnerability lies in improper handling of untrusted data during the deserialization process. Attackers can exploit this by sending maliciously crafted data, allowing them to execute arbitrary code on the server.
The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the affected systems. The attack complexity is low, requiring no special privileges or user interaction, making it accessible to a wide range of attackers.
The potential impacts of this vulnerability include high confidentiality, integrity, and availability impacts, meaning that an attacker could gain unauthorized access to sensitive data, alter data, or disrupt services.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-29300 is significant. Organizations using affected versions of Adobe ColdFusion face substantial exposure to potential attacks. The lack of user interaction required for exploitation amplifies this risk, as it enables attackers to target systems without any user involvement. The blast radius could be extensive, impacting not just the ColdFusion application but potentially other systems connected to it, thereby heightening the urgency for remediation.
Given the CVSS score of 9.8 and the KEV status, organizations should treat this vulnerability with the highest urgency and prioritize patching in their immediate patch cycle.
