CVE-2025-2530: Luxion KeyShot DAE File RCE Vulnerability

CVE-2025-2530 Overview

CVE-2025-2530 is a remote code execution vulnerability in Luxion KeyShot, a 3D rendering and animation application. The flaw exists in the parser for Digital Asset Exchange (.dae) files and stems from access of an uninitialized pointer [CWE-824]. An attacker who convinces a user to open a crafted DAE file, or to visit a page that delivers one, can execute code in the context of the KeyShot process. The issue was reported through the Trend Micro Zero Day Initiative and tracked as ZDI-CAN-23698.

Critical Impact
Successful exploitation allows arbitrary code execution in the context of the current user, exposing confidentiality, integrity, and availability of the affected workstation.

Affected Products

Luxion KeyShot (all versions prior to the vendor fix noted in ZDI-25-173)
Windows installations processing untrusted .dae (COLLADA) files
Workflows importing third-party 3D assets into KeyShot

Technical Details for CVE-2025-2530

Vulnerability Analysis

The vulnerability resides in the code path that parses COLLADA .dae files inside Luxion KeyShot. DAE is an XML-based 3D asset exchange format widely used for interoperability between modeling tools. KeyShot's parser accesses a pointer before it has been properly initialized, causing the process to dereference attacker-influenced memory. This creates a path from untrusted file content to control-flow hijacking within the rendering application.

Exploitation requires user interaction. The victim must open a malicious .dae file or visit a page that delivers such a file to KeyShot. Because KeyShot runs with the privileges of the interactive user, code executed through this bug inherits those privileges and can persist, pivot, or stage additional payloads.

Root Cause

The root cause is an improper initialization defect classified as CWE-824: Access of Uninitialized Pointer. During DAE parsing, a pointer variable is used before the code assigns it a valid object reference. When the parser reaches an attacker-controlled element or attribute, the uninitialized value determines the memory address that is read or written. Structured DAE content allows an attacker to influence surrounding heap or stack state, converting the uninitialized access into a controllable primitive.

Attack Vector

The attack is local in CVSS terms because the malicious file must be processed by KeyShot on the target host. Realistic delivery vectors include email attachments, shared asset libraries, cloud storage synced folders, and 3D marketplaces. Once the user opens the DAE file, parsing occurs automatically and the vulnerability triggers without additional prompts. No authentication to KeyShot or the operating system beyond the interactive session is required.

No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Refer to the Zero Day Initiative Advisory ZDI-25-173 for the authoritative technical description.

Detection Methods for CVE-2025-2530

Indicators of Compromise

Unexpected child processes spawned by the KeyShot executable, particularly command interpreters such as cmd.exe, powershell.exe, or rundll32.exe.
KeyShot process crashes or Windows Error Reporting entries referencing DAE import operations.
.dae files arriving from external email, chat, or download sources and opened outside sanctioned asset pipelines.

Detection Strategies

Hunt for KeyShot process trees that deviate from normal rendering behavior, especially network connections initiated shortly after a DAE file open event.
Alert on file writes of .dae files to user download or temporary directories followed by KeyShot execution within a short interval.
Inspect memory dumps of crashed KeyShot processes for parser stack frames referencing COLLADA element handlers.

Monitoring Recommendations

Forward endpoint process, file, and network telemetry to a central analytics platform for correlation across DAE handling events.
Track KeyShot version inventory on all workstations to identify hosts still running vulnerable builds.
Monitor outbound connections from workstations that routinely process third-party 3D assets for command-and-control patterns.

How to Mitigate CVE-2025-2530

Immediate Actions Required

Update Luxion KeyShot to the version identified in ZDI-25-173 as containing the vendor fix.
Instruct users to avoid opening .dae files received from untrusted sources such as unsolicited email or unfamiliar marketplaces.
Audit shared asset repositories and remove .dae files that lack a verified origin.

Patch Information

Luxion has addressed the uninitialized pointer defect in an updated KeyShot release referenced through the Zero Day Initiative advisory. Administrators should consult the ZDI-25-173 advisory and the Luxion download portal to confirm the fixed version and apply it across all workstations that render or preview COLLADA content.

Workarounds

Restrict DAE imports to files originating from trusted internal pipelines only, using file-hash allowlists where feasible.
Run KeyShot under a standard user account with no local administrator rights to limit blast radius from successful exploitation.
Use application allowlisting to prevent KeyShot from spawning script interpreters or shells as child processes.

bash

# Example: block KeyShot from launching common living-off-the-land binaries
# (Windows Defender Application Control / AppLocker rule concept)
Deny: keyshot.exe -> cmd.exe, powershell.exe, wscript.exe, cscript.exe, rundll32.exe
