CVE-2026-48282 is a critical path traversal vulnerability in Adobe ColdFusion affecting ColdFusion 2025 Update 9 and earlier and ColdFusion 2023 Update 20 and earlier. The flaw is associated with improper limitation of a pathname to a restricted directory and has been reported in the Remote Development Services (RDS) FILEIO handler exposed through a ColdFusion web endpoint. By supplying crafted path input, a remote attacker can traverse outside the intended directory and perform unauthorized file system operations, including arbitrary file read and arbitrary file write. Public reporting indicates the issue can be exploited without user interaction and, in exposed configurations, without authentication. The write primitive can be used to place attacker-controlled ColdFusion markup or other executable server-side content into a web-accessible location, resulting in arbitrary code execution in the context of the ColdFusion service or current user.

Repository is a small standalone Python exploit PoC for CVE-2026-48282 targeting Adobe ColdFusion RDS path traversal/RCE. Structure is minimal: one main Python script, one README, and a requirements file. The exploit is not part of a larger framework. The main script, CVE-2026-48282.py, implements a custom client for the ColdFusion RDS protocol over HTTP POST requests to CFIDE endpoints. It defines helper routines to encode RDS operations such as READ, WRITE, BrowseDir, and Existence checks, then wraps communication in an RDSSession class that tests multiple endpoint variants. The exploit supports vulnerability checking using known canary files, arbitrary file reads, directory browsing, file existence probing, and arbitrary file writes. Its primary offensive capability is escalation from path traversal/file access to remote code execution by locating a writable webroot from a hardcoded list of common ColdFusion/IIS/Apache/XAMPP paths on Windows and Linux, writing a ColdFusion webshell there, and invoking it to run attacker-supplied commands. This makes it more than a detector: it is an operational exploit with a basic hardcoded payload path and shell deployment workflow. Fingerprintable targets include the ColdFusion RDS endpoint /CFIDE/main/ide.cfm and two query-string variants, plus numerous candidate filesystem paths used for canary reads and shell placement. README examples further show intended post-exploitation targets such as password.properties, neo-query.xml, /etc/passwd, and /etc/shadow. Overall purpose: unauthenticated exploitation of exposed/vulnerable Adobe ColdFusion RDS to validate exposure, extract sensitive files, browse the server filesystem, and achieve RCE through webshell deployment.
