CVE-2024-20767: 
Adobe ColdFusion 2021 vulnerability analysis and mitigation

CVE-2024-20767 is an Improper Access Control vulnerability affecting Adobe ColdFusion versions 2023.6, 2021.12, and earlier. The vulnerability was discovered and disclosed on March 18, 2024. This security flaw could result in arbitrary file system read capabilities, allowing attackers to access or modify restricted files. The exploitation does not require user interaction but requires the admin panel to be exposed to the internet (NVD, Adobe Advisory).

The vulnerability has been assigned a CVSS v3.1 base score of 7.4 (High) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N. The vulnerability is classified under CWE-284 (Improper Access Control). The technical exploitation involves requesting an authentication token in the form of a UUID from the /CFIDE/adminapi/servermanager/servermanager.cfc endpoint, which can then be used to exploit the arbitrary file read vulnerability through the /pms endpoint (NVD, [Rapid7](https://www.rapid7.com/db/modules/auxiliary/gather/coldfusionpmsservletfile_read/)).

The vulnerability enables attackers to perform arbitrary file system read operations and potentially modify restricted files. This could lead to unauthorized access to sensitive information and compromise of system security. The high severity rating indicates significant potential impact on the confidentiality and integrity of affected systems (NVD).

CISA requires Federal Civilian Executive Branch (FCEB) agencies to remediate this vulnerability by January 6, 2025. Organizations are strongly urged to apply vendor-provided mitigations or discontinue use of the product if mitigations are unavailable. Adobe has released security updates to address this vulnerability in newer versions of ColdFusion (CISA Alert).
