CVE-2025-43548 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Dimension versions 4.1.2 and earlier. This vulnerability arises when the software improperly handles memory boundaries, allowing an attacker to write data outside the intended buffer. Exploitation requires user interaction, specifically the victim opening a maliciously crafted file in Adobe Dimension. Successful exploitation can lead to arbitrary code execution within the context of the current user, potentially compromising confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score of 7.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction and local access vector. No known exploits are currently reported in the wild, and no patches have been released yet. Adobe Dimension is a 3D design and rendering application used primarily by creative professionals for product mockups and visualizations. The vulnerability's exploitation could allow attackers to execute malicious code, install malware, or escalate privileges depending on the user's permissions, leading to significant security risks.

For European organizations, the impact of this vulnerability can be substantial, especially in sectors relying on Adobe Dimension for design and marketing workflows, such as manufacturing, retail, advertising, and media. Compromise of systems running Adobe Dimension could lead to intellectual property theft, disruption of design processes, and potential lateral movement within corporate networks. Since exploitation requires user interaction, targeted phishing or social engineering campaigns could be used to deliver malicious files. The arbitrary code execution capability means attackers could deploy ransomware, spyware, or other malware, impacting business continuity and data confidentiality. Organizations with less mature endpoint security or lacking strict file handling policies are at higher risk. Additionally, the vulnerability could be leveraged in supply chain attacks if malicious files are distributed through trusted partners or collaborators.

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: (1) Restricting Adobe Dimension usage to trusted users and environments; (2) Implementing strict email and file filtering to block or quarantine suspicious files, especially those with extensions associated with Adobe Dimension projects; (3) Educating users on the risks of opening unsolicited or unexpected files; (4) Employing application whitelisting and sandboxing techniques to limit the execution scope of Adobe Dimension; (5) Monitoring endpoint behavior for unusual activities indicative of exploitation attempts; (6) Utilizing endpoint detection and response (EDR) tools to detect and respond to anomalous code execution; (7) Preparing incident response plans specific to potential exploitation scenarios; and (8) Planning for rapid deployment of patches once Adobe releases a fix. Network segmentation to isolate design workstations can further reduce risk.
