CVE-2025-54229: Adobe Framemaker RCE Vulnerability

CVE-2025-54229 Overview

CVE-2025-54229 is a Use After Free vulnerability [CWE-416] affecting Adobe Framemaker versions 2020.8, 2022.6, and earlier. The flaw can result in arbitrary code execution in the context of the current user. Exploitation requires user interaction: a victim must open a malicious file crafted by an attacker.

Adobe published the advisory APSB25-83 addressing this issue. The vulnerability carries a CVSS 3.1 base score of 7.8 and is exploitable locally with low complexity. No public proof-of-concept code or in-the-wild exploitation has been reported.

Critical Impact
A successful exploit grants arbitrary code execution under the privileges of the user running Adobe Framemaker, enabling installation of malware, data theft, or lateral movement on the affected Windows host.

Affected Products

Adobe Framemaker 2020.8 and earlier
Adobe Framemaker 2022.6 and earlier
Microsoft Windows (host platform for affected Framemaker installations)

Technical Details for CVE-2025-54229

Vulnerability Analysis

The vulnerability is a Use After Free (UAF) condition in Adobe Framemaker's file parsing logic. A UAF occurs when an application continues to reference memory after it has been freed. Attackers who can control the contents of the freed region can redirect execution flow.

Framemaker processes complex document formats including FrameMaker Markup Language (FM), Maker Interchange Format (MIF), and XML-based structured documents. Parsing errors in any of these handlers can release an object while a dangling pointer remains in use. The attacker-supplied document triggers reuse of that pointer, leading to controlled memory access and code execution.

The attack vector is local (AV:L), but the impact across confidentiality, integrity, and availability is high. Code executes with the privileges of the logged-in user opening the file.

Root Cause

The underlying defect is improper object lifetime management within Framemaker's parser. Specific allocations are released without invalidating all pointers referencing them. When the parser later dereferences the stale pointer, attacker-controlled heap data is interpreted as a valid object, including vtable pointers used for virtual method dispatch.

Attack Vector

Exploitation requires social engineering. An attacker delivers a malicious Framemaker document by email, file share, or web download. When the victim opens the file with a vulnerable Framemaker version, the parser triggers the UAF and executes attacker-supplied shellcode. No network access or elevated privileges are required prior to exploitation.

No public exploit code is currently available. Refer to the Adobe Security Advisory APSB25-83 for vendor technical details.

Detection Methods for CVE-2025-54229

Indicators of Compromise

Unexpected child processes spawned by FrameMaker.exe, particularly cmd.exe, powershell.exe, or rundll32.exe.
Framemaker process crashes logged in the Windows Application event log with access violation exceptions in heap-related modules.
Outbound network connections originating from FrameMaker.exe to untrusted hosts following the opening of an external document.

Detection Strategies

Hunt for Framemaker process trees that deviate from baseline behavior, especially document opens that result in script interpreter execution.
Monitor file write activity from FrameMaker.exe into %TEMP%, %APPDATA%, or startup locations.
Correlate email gateway logs and endpoint telemetry to flag inbound .fm, .mif, or .book files from external senders.

Monitoring Recommendations

Enable Windows Defender Exploit Guard or equivalent exploit mitigation logging for Framemaker binaries.
Forward Sysmon Process Create (Event ID 1) and Image Load (Event ID 7) events to a centralized log platform for Framemaker hosts.
Track user-reported document crashes on workstations running Framemaker as a triage signal for targeted attacks.

How to Mitigate CVE-2025-54229

Immediate Actions Required

Update Adobe Framemaker to the fixed releases identified in Adobe Security Advisory APSB25-83.
Inventory all endpoints with Framemaker installed and prioritize patching for users who routinely receive external documents.
Instruct users not to open Framemaker files originating from untrusted email, chat, or web sources until patching is complete.

Patch Information

Adobe has released security updates for Adobe Framemaker that remediate CVE-2025-54229. Administrators should consult Adobe Security Advisory APSB25-83 for the specific fixed versions and download instructions. Apply the updates to all installations of Framemaker 2020.x and 2022.x running on Windows.

Workarounds

Restrict Framemaker file associations so that documents from internet zones do not auto-open in the application.
Apply Windows Attack Surface Reduction (ASR) rules to block child process creation from Office and document-handling applications where feasible.
Use Mark-of-the-Web enforcement and Protected View workflows so external documents are reviewed in an isolated environment before being opened in Framemaker.
