CVE-2024-30274 is an out-of-bounds write vulnerability classified under CWE-787 affecting Adobe Substance3D - Painter, a widely used 3D texturing and painting software. The flaw exists in versions 9.1.2 and earlier, where improper bounds checking during file processing allows an attacker to write data outside the intended memory buffer. This memory corruption can lead to arbitrary code execution within the context of the current user. The attack vector requires a victim to open a maliciously crafted file, which triggers the vulnerability. No elevated privileges or authentication are required, but user interaction is mandatory. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, system compromise, or denial of service. The CVSS 3.1 base score is 7.8, reflecting high severity with local attack vector, low attack complexity, no privileges required, user interaction needed, and full impact on confidentiality, integrity, and availability. Currently, there are no publicly known exploits in the wild, but the vulnerability poses a significant risk to users of the affected software. Adobe has not yet published a patch or mitigation guidance, so users must rely on interim protective measures.

For European organizations, especially those in digital content creation, gaming, and media production sectors that rely on Adobe Substance3D - Painter, this vulnerability poses a substantial risk. Successful exploitation can lead to arbitrary code execution, enabling attackers to steal sensitive intellectual property, disrupt production workflows, or deploy malware and ransomware. The impact extends to confidentiality breaches of proprietary designs and potential integrity violations of digital assets. Availability may also be affected if attackers cause application crashes or system instability. Given the requirement for user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The risk is heightened in environments where users frequently exchange project files externally or download assets from untrusted sources. Without timely patching, organizations face increased exposure to targeted attacks that could compromise their creative and operational capabilities.

1. Monitor Adobe’s official channels for patches and apply updates to Substance3D - Painter immediately upon release. 2. Until a patch is available, restrict the opening of files from untrusted or unknown sources within the application. 3. Implement strict email and file filtering to block or quarantine suspicious attachments that could contain malicious Substance3D project files. 4. Educate users on the risks of opening unsolicited or unexpected files, emphasizing caution with files received via email or external media. 5. Deploy endpoint detection and response (EDR) solutions capable of detecting anomalous behavior indicative of exploitation attempts, such as unexpected memory writes or code execution. 6. Use application whitelisting to limit execution of unauthorized code and sandboxing techniques to isolate the application environment. 7. Maintain regular backups of critical project files and systems to enable recovery in case of compromise. 8. Review and enforce least privilege policies to minimize the impact of code execution under user context.
