CVE-2025-61800: Adobe Dimension RCE Vulnerability

CVE-2025-61800 Overview

CVE-2025-61800 is an integer overflow or wraparound vulnerability [CWE-190] affecting Adobe Dimension versions 4.1.4 and earlier. The flaw allows arbitrary code execution in the context of the current user when a victim opens a malicious file. Exploitation requires local access and user interaction, but no authentication. Adobe addressed the issue in security advisory APSB25-103.

Critical Impact
Successful exploitation grants attackers arbitrary code execution with the privileges of the logged-in user, enabling installation of malware, data theft, or persistence on Windows and macOS systems running vulnerable versions of Adobe Dimension.

Affected Products

Adobe Dimension versions 4.1.4 and earlier
Microsoft Windows installations of Adobe Dimension
Apple macOS installations of Adobe Dimension

Technical Details for CVE-2025-61800

Vulnerability Analysis

The vulnerability is classified as an integer overflow or wraparound [CWE-190] in Adobe Dimension. Integer overflow flaws occur when arithmetic operations produce values exceeding the storage capacity of the target integer type. The result wraps around to an unexpected value. In file parsing routines, this typically corrupts size calculations used for memory allocation or buffer indexing.

When Adobe Dimension processes a crafted file, the overflow leads to undersized buffer allocations or incorrect offset calculations. Subsequent read or write operations then occur outside intended memory boundaries. Attackers can shape the malicious file to control adjacent memory and redirect execution flow.

The EPSS score of 0.201% reflects a low predicted exploitation probability in the near term. However, the local attack vector combined with high impact on confidentiality, integrity, and availability makes this a meaningful risk for endpoints where users open untrusted design assets.

Root Cause

The root cause is improper validation of integer values used in size or length computations during file parsing. Adobe has not publicly released a detailed technical breakdown of the affected component. Refer to the Adobe Security Advisory APSB25-103 for vendor guidance.

Attack Vector

The attack vector is local and requires user interaction. An attacker delivers a malicious Dimension project or asset file through email, messaging, a file share, or a compromised website. When the victim opens the file in Adobe Dimension, the integer overflow triggers and code executes with the user's privileges. No prior authentication on the target system is required.

No verified public proof-of-concept code is available. See the Adobe Security Advisory APSB25-103 for technical context.

Detection Methods for CVE-2025-61800

Indicators of Compromise

Unexpected child processes spawned by Dimension.exe on Windows or the Dimension binary on macOS, such as command shells, scripting engines, or rundll32.exe.
Adobe Dimension reading files from untrusted locations such as email attachment caches, browser download folders, or removable media.
Crash dumps or Windows Error Reporting events referencing Adobe Dimension following the opening of a third-party file.

Detection Strategies

Monitor process lineage for Adobe Dimension spawning interpreters such as cmd.exe, powershell.exe, bash, or osascript.
Apply YARA or content inspection rules to flag Dimension project files with anomalous size headers or malformed asset chunks.
Correlate file-open telemetry from EDR with subsequent network connections initiated by the Dimension process.

Monitoring Recommendations

Inventory endpoints running Adobe Dimension and confirm installed versions against the patched release listed in APSB25-103.
Forward Adobe Dimension process telemetry and file-access events to a centralized SIEM for behavioral analysis.
Alert on outbound network connections from Dimension.exe to non-Adobe domains, which is uncharacteristic for normal use.

How to Mitigate CVE-2025-61800

Immediate Actions Required

Update Adobe Dimension to the version specified in Adobe Security Advisory APSB25-103 on all Windows and macOS endpoints.
Audit endpoints for installations of Adobe Dimension 4.1.4 or earlier and prioritize remediation for users handling external design assets.
Instruct users to avoid opening Dimension files received from untrusted sources until patches are applied.

Patch Information

Adobe released a security update addressing CVE-2025-61800. Refer to the Adobe Security Advisory APSB25-103 for the fixed version and download links. Apply the update through enterprise software distribution tools or the Adobe Creative Cloud client.

Workarounds

Restrict execution of Adobe Dimension to users with a documented business need until patching completes.
Use application allowlisting and email gateway controls to block delivery of Dimension project files from external senders.
Run Adobe Dimension under standard user accounts rather than administrative accounts to limit the impact of code execution.
