CVE-2025-43572 Overview
CVE-2025-43572 is an out-of-bounds write vulnerability [CWE-787] in Adobe Dimension versions 4.1.2 and earlier. Successful exploitation allows attackers to execute arbitrary code in the context of the current user. The vulnerability requires user interaction, as a victim must open a malicious file crafted by the attacker.
Adobe addressed the issue in security bulletin APSB25-45. The flaw affects Adobe Dimension on both Microsoft Windows and Apple macOS platforms.
Critical Impact
Attackers can achieve arbitrary code execution with the privileges of the targeted user when a malicious Dimension file is opened.
Affected Products
- Adobe Dimension 4.1.2 and earlier
- Apple macOS (host platform)
- Microsoft Windows (host platform)

Technical Details for CVE-2025-43572
Vulnerability Analysis
The vulnerability is an out-of-bounds write condition [CWE-787] within Adobe Dimension's file parsing logic. When Dimension processes a crafted file, the application writes data beyond the boundaries of an allocated memory buffer. This memory corruption can be leveraged to overwrite adjacent structures, including function pointers or control-flow data.
Attackers who control the out-of-bounds write can redirect execution into attacker-supplied payloads. Code runs with the same privileges as the user opening the file. The attack vector is local, but distribution can occur through email attachments, file shares, or malicious websites delivering crafted assets.
Root Cause
The root cause is insufficient bounds checking during deserialization of input from a file. Adobe Dimension fails to validate field sizes or offsets before writing to memory, allowing crafted values to drive a write past the end of an intended buffer.
Attack Vector
Exploitation requires a victim to open a malicious file in Adobe Dimension. An attacker prepares a file with manipulated structures that trigger the out-of-bounds write during parsing. No elevated privileges are required to launch the exploit. Successful exploitation yields arbitrary code execution in the user's session.
No public proof-of-concept exploit is available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-43572
Indicators of Compromise
- Unexpected child processes spawned by Dimension.exe (Windows) or the Adobe Dimension binary (macOS), such as command shells or scripting hosts.
- Crashes or anomalous termination of Adobe Dimension when opening files received via email or download.
- Adobe Dimension files (.dn) originating from untrusted sources or with abnormal structures.
Detection Strategies
- Monitor process lineage for Adobe Dimension spawning interpreters, shells, or LOLBins.
- Alert on file writes to autostart locations or temporary directories immediately after a Dimension process launch.
- Use behavioral analytics to flag memory corruption indicators such as access violations in Dimension.exe.
Monitoring Recommendations
- Collect endpoint telemetry covering process creation, image loads, and child process activity from creative software.
- Forward Adobe Dimension crash reports and Windows Error Reporting events to centralized logging for review.
- Track inbound file deliveries containing Dimension assets through email and web gateways.
How to Mitigate CVE-2025-43572
Immediate Actions Required
- Update Adobe Dimension to the version released in Adobe security bulletin APSB25-45.
- Inventory endpoints running Adobe Dimension and prioritize patching workstations belonging to designers and creative teams.
- Block delivery of untrusted Dimension files at email and web proxy gateways until patching completes.
Patch Information
Adobe released a fixed version of Dimension in Adobe Security Advisory APSB25-45. Administrators should deploy the updated version on all systems where Adobe Dimension 4.1.2 or earlier is installed.
Workarounds
- Restrict opening of Adobe Dimension files to those received from trusted internal sources.
- Run Adobe Dimension under standard user accounts rather than administrative accounts to limit exploitation impact.
- Educate users to avoid opening unsolicited Dimension files and to verify file origin before use.
