CVE-2025-24450 is an out-of-bounds write vulnerability classified under CWE-787 affecting Adobe Substance3D - Painter versions 10.1.2 and earlier. The vulnerability arises when the software improperly handles input data from files, allowing an attacker to write data outside the intended buffer boundaries. This memory corruption can be leveraged to execute arbitrary code within the context of the current user. Exploitation requires the victim to open a maliciously crafted file, making social engineering or phishing a likely attack vector. The vulnerability does not require prior authentication, increasing its risk profile. The CVSS v3.1 base score is 7.8, with vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. No patches or exploit code are currently publicly available, but the flaw poses a significant risk to users of the affected software, particularly in environments where untrusted files may be opened. Adobe Substance3D - Painter is widely used in digital content creation, making this vulnerability relevant to creative professionals and organizations relying on Adobe's 3D painting tools.

The vulnerability allows attackers to execute arbitrary code with the same privileges as the current user, potentially leading to full system compromise. This can result in unauthorized access to sensitive data, modification or destruction of files, and disruption of system availability. Since exploitation requires opening a malicious file, targeted spear-phishing or supply chain attacks could be effective. Organizations in creative industries, digital media, and any sector using Adobe Substance3D - Painter are at risk. The impact extends to intellectual property theft, operational disruption, and potential lateral movement within networks if the compromised user has elevated privileges. The lack of known exploits in the wild currently limits immediate widespread impact, but the high severity score indicates that once exploit code becomes available, rapid exploitation could occur.

1. Monitor Adobe security advisories closely and apply patches immediately once released for Substance3D - Painter. 2. Implement strict file handling policies, including disabling or restricting the opening of files from untrusted or unknown sources. 3. Educate users about the risks of opening unsolicited or suspicious files, emphasizing the importance of verifying file origins. 4. Employ endpoint protection solutions capable of detecting anomalous behavior related to memory corruption exploits. 5. Use application whitelisting to limit execution of unauthorized code. 6. Consider sandboxing or running Substance3D - Painter in isolated environments to contain potential exploitation. 7. Maintain regular backups of critical data to enable recovery in case of compromise. 8. Network segmentation can limit lateral movement if a user endpoint is compromised. 9. Review and restrict user privileges to minimize the impact of code execution under user context.
