CVE-2023-47081 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance 3D Stager versions 2.1.1 and earlier. This vulnerability allows an attacker to read memory outside the intended buffer boundaries, potentially disclosing sensitive information stored in adjacent memory regions. Such information disclosure can include data that may help bypass security mitigations like Address Space Layout Randomization (ASLR), which is designed to prevent exploitation of memory corruption vulnerabilities by randomizing memory addresses. The exploitation requires user interaction, specifically that the victim opens a maliciously crafted file in the vulnerable application. The vulnerability does not require any privileges or authentication, but the attacker must convince the user to open the malicious file. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), but requires user interaction (UI:R). The impact is high on confidentiality (C:H) but no impact on integrity or availability. No known exploits are reported in the wild as of the published date. The vulnerability is significant because Adobe Substance 3D Stager is used in 3D content creation workflows, and disclosure of memory contents could leak sensitive project data or internal application state, potentially aiding further exploitation or intellectual property theft.

For European organizations, the impact of this vulnerability depends on the adoption of Adobe Substance 3D Stager in their digital content creation, design, and manufacturing sectors. Organizations involved in media, entertainment, industrial design, and advertising that use this software could face confidentiality breaches if malicious files are opened by employees. The disclosure of sensitive memory could reveal proprietary design data or credentials stored in memory, leading to intellectual property theft or facilitating subsequent attacks. While the vulnerability does not directly affect system integrity or availability, the ability to bypass ASLR could enable more sophisticated exploitation chains. This risk is particularly relevant for organizations handling sensitive or regulated data under GDPR, where unauthorized disclosure could lead to compliance violations and reputational damage. The requirement for user interaction means that phishing or social engineering campaigns could be used to deliver malicious files, increasing the risk in environments with less stringent user awareness training.

To mitigate this vulnerability, European organizations should: 1) Immediately update Adobe Substance 3D Stager to the latest version once Adobe releases a patch addressing CVE-2023-47081. 2) Until a patch is available, implement strict controls on file sources by restricting the opening of files from untrusted or unknown origins within Substance 3D Stager. 3) Enhance user awareness training to recognize and avoid opening suspicious or unsolicited files, emphasizing the risk of targeted social engineering attacks. 4) Employ endpoint protection solutions capable of detecting anomalous behavior related to file handling in creative applications. 5) Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 6) Monitor network and endpoint logs for unusual activity that could indicate attempts to exploit this vulnerability or related memory disclosure attempts. 7) Review and enforce data classification and handling policies to minimize exposure of sensitive project files to unauthorized users.
