Critical vulnerabilities in Adobe Coldfusion (CVE-2023-26359, CVE-2023-26360 and CVE-2023-26359)

On March 8, 2023, Adobe released security updates to address critical vulnerabilities in Adobe ColdFusion, a popular web application development platform. These vulnerabilities, classified as improper access control and insecure deserialization lead to unauthorized Remote Code Execution (RCE) when an attacker sends a specially crafted request containing untrusted data to a ColdFusion server.

The exploitation does not require user interaction, making it particularly severe as it allows attackers to execute arbitrary code in the context of the current user without their knowledge.

The Cybersecurity and Infrastructure Security Agency (CISA) highlighted the gravity of this issue on December 5, 2023, by releasing an advisory regarding the active exploitation of the issues. They noted that this vulnerability is being utilized by cyber threat actors to gain initial access to public-facing Adobe ColdFusion web servers. The most severe vulnerability has a CVSS score of 9.8, categorizing it as Critical.

So basically after some further investigation, three different issues were identified:

1. CVE-2023-26359: Deserialization of Untrusted Data vulnerability that could result in arbitrary code execution in the context of the current user.
2. CVE-2023-26360: Initially it was recognized as an Improper Access Control vulnerability that could result in arbitrary code execution in the context of the current user, but later on Adobe changed it to Deserialization of Untrusted Data.
3. CVE-2023-26361: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could result in Arbitrary file system read.
