CVE-2025-54238: Adobe Dimension Information Disclosure

CVE-2025-54238 Overview

Adobe Dimension versions 4.1.3 and earlier contain an out-of-bounds read vulnerability [CWE-125] that can disclose sensitive process memory. Exploitation requires user interaction: a victim must open a crafted file in Adobe Dimension. Successful exploitation discloses memory contents to the attacker but does not directly affect integrity or availability. Adobe addressed the issue in security advisory APSB25-84. The vulnerability affects Dimension installations on both Apple macOS and Microsoft Windows.

Critical Impact
Opening a malicious Dimension file allows an attacker to read adjacent process memory, potentially exposing data such as pointers, cryptographic material, or other in-memory secrets that aid further exploitation.

Affected Products

Adobe Dimension 4.1.3 and earlier
Apple macOS (Dimension installations)
Microsoft Windows (Dimension installations)

Technical Details for CVE-2025-54238

Vulnerability Analysis

The flaw is an out-of-bounds read in Adobe Dimension's file parsing path. When Dimension loads a malicious asset or scene file, the parser reads memory past the end of an allocated buffer. The out-of-bounds data is then processed or returned in a way that exposes it to the attacker. The impact is scoped to confidentiality: an attacker gains the ability to leak portions of process memory. There is no integrity or availability impact reported. Memory disclosure vulnerabilities of this class are often chained with memory-corruption bugs to bypass Address Space Layout Randomization (ASLR) and other mitigations.

Root Cause

The root cause is missing or insufficient bounds validation in Dimension's parsing logic for untrusted input files. The parser trusts a length, index, or offset value derived from attacker-controlled file data and performs a read beyond the valid buffer boundary. This maps to the Common Weakness Enumeration category [CWE-125] (Out-of-Bounds Read).

Attack Vector

The attack vector is local and requires user interaction. An attacker must deliver a malicious Dimension-compatible file to the victim through email, download, or shared storage. The victim must then open the file in a vulnerable Dimension client. No elevated privileges are required by the attacker, but the exploit runs with the privileges of the user opening the file. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, and no public proof-of-concept exploit has been published.

No verified exploit code is public. Refer to the Adobe Security Advisory APSB25-84 for vendor technical details.

Detection Methods for CVE-2025-54238

Indicators of Compromise

Unexpected Dimension document files (.dn, 3D model formats) delivered via email, chat, or external storage from untrusted senders.
Dimension process crashes, hangs, or anomalous memory consumption shortly after opening a file.
Dimension spawning unexpected child processes or initiating outbound network connections after rendering a file.

Detection Strategies

Inventory endpoints running Adobe Dimension and flag any version at or below 4.1.3.
Monitor file-open telemetry for Dimension processes handling files sourced from browser downloads, email attachments, or removable media.
Correlate Dimension process crashes with recent file-open events to identify potential exploitation attempts.

Monitoring Recommendations

Ingest endpoint process and file telemetry into a centralized data lake for retrospective hunting on Dimension file-handling events.
Alert on Dimension processes exhibiting abnormal memory read patterns or crash signatures consistent with out-of-bounds access.
Track email and web gateways for 3D asset file types delivered from external domains.

How to Mitigate CVE-2025-54238

Immediate Actions Required

Upgrade Adobe Dimension to the fixed release identified in Adobe Security Advisory APSB25-84.
Instruct users not to open Dimension files received from untrusted or unverified sources until patched.
Validate the Dimension version deployed across both macOS and Windows endpoints using software inventory tools.

Patch Information

Adobe published the fix in security bulletin APSB25-84. Administrators should deploy the vendor-supplied update to all Dimension installations on macOS and Windows. See the Adobe Security Advisory APSB25-84 for the specific fixed version and download instructions.

Workarounds

Block or quarantine Dimension-compatible file types at email and web gateways when sourced from external senders.
Restrict Dimension to systems that process only trusted internal assets until the patch is deployed.
Apply application allowlisting to limit which users can launch Dimension in high-risk environments.
