CVE-2023-29277 in Substance 3D Painter
Summary
by MITRE • 05/12/2023
Adobe Substance 3D Painter versions 8.3.0 (and earlier) is affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe Substance 3D Painter version 8.3.0 and earlier contains a critical out-of-bounds read vulnerability that presents significant security risks to users and organizations. This vulnerability falls under the Common Weakness Enumeration category CWE-125, which describes out-of-bounds read conditions where a program attempts to access memory beyond the boundaries of a valid buffer. The flaw specifically affects the application's handling of maliciously crafted files during the parsing process, creating a pathway for unauthorized memory access that could expose sensitive system information.
The technical implementation of this vulnerability occurs when the application processes specially crafted input files without proper boundary checking mechanisms. During file parsing operations, the software fails to validate array indices or buffer limits, allowing an attacker to manipulate input data in such a way that subsequent memory reads access unauthorized memory regions. This memory access pattern can potentially reveal stack contents, heap data, or other sensitive information stored in adjacent memory locations. The vulnerability is particularly concerning because it operates at the memory access level where address space layout randomization protections might be bypassed, effectively undermining modern exploit mitigations.
The operational impact of this vulnerability extends beyond simple information disclosure, as it creates opportunities for more sophisticated attacks that can circumvent security protections designed to prevent exploitation. When an attacker successfully triggers this vulnerability, they can potentially gather information about memory layout that would normally be protected by ASLR, making subsequent exploitation attempts more successful. The requirement for user interaction through file opening creates a social engineering component to the attack vector, as victims must be convinced to open malicious files. This interaction requirement does not eliminate the severity of the vulnerability but rather indicates that exploitation would need to be carefully orchestrated through phishing or other delivery mechanisms.
Security professionals should consider this vulnerability in the context of the ATT&CK framework, particularly under the technique T1059.007 for command and script interpreter and T1566 for phishing attacks. The vulnerability serves as a potential initial access point that could lead to more comprehensive compromise scenarios. Organizations using Adobe Substance 3D Painter should prioritize immediate patching of affected versions, as the vulnerability exists in the core file processing functionality. System administrators should also implement monitoring for suspicious file opening activities and consider network-based detection measures to identify potential exploitation attempts. The vulnerability demonstrates the critical importance of input validation and boundary checking in preventing memory corruption issues that can undermine fundamental security protections.
