The vulnerability in question, CVE-2023-26360, poses a substantial threat and is categorized as an improper access control issue. It enables threat actors to execute arbitrary code, wreaking potential havoc within affected systems. Adobe ColdFusion versions 2018 Update 15 (and earlier) and 2021 Update 5 (and earlier) are susceptible to this exploit. ColdFusion, widely used for rapid web application development, facilitates the creation of web applications and integration with databases and third-party assets. 

The timeline of attacks is concerning. On June 26, 2023, threat actors exploited the vulnerability in Adobe ColdFusion v2016.0.0.3, marking the inception of the breach. Another incident on June 2, 2023, targeted a web server running Adobe ColdFusion v2021.0.0.2. These breaches highlight the urgency for quick action against this exploit. 

CISA’s investigation indicated that the affected agencies were running outdated software versions, making them vulnerable to various threats, including CVE-2023-26360. Malware insertion and reconnaissance campaigns were the primary objectives of the threat actors. However, there’s no evidence of data exfiltration or lateral movement within the breached systems. The impacted agencies managed to contain and lock out the attackers within a 24-hour window.
