Critical Adobe ColdFusion Flaw Under Active Attack
A critical security vulnerability affecting Adobe ColdFusion has come to light, with Adobe issuing an urgent patch and confirming the existence of publicly available exploit code. The flaw, tracked as CVE-2024-53961, is a path traversal vulnerability that could allow malicious actors to read arbitrary files on affected servers, potentially exposing sensitive data.
Adobe has classified this issue as “Priority 1,” its highest severity rating, underscoring the significant risk it poses to organizations using ColdFusion. This designation means that the vulnerability is actively being targeted or is at high risk of exploitation.
The affected versions of ColdFusion include 2023 (up to Update 11) and 2021 (up to Update 17). The availability of a proof-of-concept (PoC) exploit significantly amplifies the danger, as it provides attackers with a readily available blueprint for launching attacks. This makes patching absolutely crucial for all affected users.
Adobe strongly advises all users running vulnerable versions to immediately apply the necessary updates. These updates address CVE-2024-53961 and other security issues. The company has published a security bulletin (APSB24-107) with detailed information about the vulnerability and instructions on how to obtain and install the patches.

For organizations unable to immediately implement the updates, Adobe recommends implementing mitigating controls to reduce the risk of exploitation. These measures could include network segmentation, firewall rules, and intrusion detection/prevention systems. However, these are only temporary measures, and patching remains the most effective solution.
This isn’t the first time ColdFusion has been targeted by attackers. In July 2023, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) even issued a directive ordering federal agencies to patch critical ColdFusion vulnerabilities due to active exploitation. This history highlights the importance of staying vigilant and promptly applying security updates for ColdFusion deployments. The rapid emergence of exploit code following vulnerability disclosure emphasizes the need for organizations to prioritize security patching and maintain a robust security posture.
