CVE-2025-47128 is an integer underflow vulnerability classified under CWE-191 affecting Adobe Framemaker versions 2020.8, 2022.6, and earlier. Integer underflow occurs when an arithmetic operation causes a variable to wrap around below its minimum representable value, potentially leading to memory corruption. In this case, the vulnerability can be triggered by opening a maliciously crafted Framemaker file, which causes the application to process data incorrectly, leading to arbitrary code execution within the context of the current user. The vulnerability requires user interaction, specifically opening a malicious file, but does not require any prior authentication or elevated privileges. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Although no exploits are currently known in the wild, the vulnerability poses a significant risk due to the widespread use of Adobe Framemaker in technical documentation and publishing environments. The lack of an available patch at the time of reporting increases exposure. Attackers could leverage this vulnerability to execute malicious code, potentially leading to data theft, system compromise, or disruption of services.

The vulnerability allows attackers to execute arbitrary code with the same privileges as the user running Adobe Framemaker, potentially leading to full compromise of the affected system. This can result in unauthorized access to sensitive documentation, intellectual property theft, or disruption of business operations. Since Framemaker is often used in enterprise environments for technical publishing, exploitation could impact organizations relying on this software for critical documentation workflows. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where users frequently exchange Framemaker files. The absence of known exploits currently reduces immediate threat but does not preclude future active exploitation. Organizations failing to address this vulnerability may face data breaches, operational downtime, and reputational damage.

1. Monitor Adobe’s official channels for patches addressing CVE-2025-47128 and apply updates promptly once available. 2. Until patches are released, implement strict file handling policies to restrict opening Framemaker files from untrusted or unknown sources. 3. Employ endpoint protection solutions capable of detecting and blocking suspicious file behaviors related to Framemaker. 4. Educate users about the risks of opening unsolicited or unexpected Framemaker files, emphasizing cautious handling of email attachments and downloads. 5. Use application whitelisting to limit execution of unauthorized code and reduce attack surface. 6. Consider sandboxing or isolating Framemaker usage environments to contain potential exploitation. 7. Regularly back up critical documentation and systems to enable recovery in case of compromise. 8. Monitor logs and network traffic for unusual activity indicative of exploitation attempts.
