CVE-2022-38441 in Dimension
Summary
by MITRE • 10/15/2022
Adobe Dimension versions 3.4.5 is affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe Dimension version 3.4.5 contains a critical out-of-bounds read vulnerability that stems from improper input validation during file parsing operations. This vulnerability falls under the CWE-125 weakness category, which specifically addresses out-of-bounds read conditions where an application attempts to read memory beyond the allocated buffer boundaries. The flaw manifests when the software processes a maliciously crafted file that contains malformed data structures, causing the parsing routine to access memory locations that extend beyond the intended buffer limits. This type of vulnerability represents a fundamental memory safety issue that can lead to unpredictable behavior and potential code execution.
The technical exploitation of this vulnerability requires an attacker to craft a malicious file that triggers the specific parsing path containing the out-of-bounds read condition. When a user opens this crafted file within Adobe Dimension, the application's file parser encounters the malformed data and attempts to read beyond the allocated memory structure, potentially accessing adjacent memory regions. This memory access violation can result in information disclosure, application crashes, or more critically, arbitrary code execution within the context of the currently logged-in user. The vulnerability's exploitation requires user interaction, meaning that social engineering or phishing techniques would be necessary to deliver the malicious payload effectively.
From an operational perspective, this vulnerability presents significant risk to organizations that rely on Adobe Dimension for creative workflows and 3D design tasks. The requirement for user interaction provides a potential defense mechanism through user education and awareness programs, but it also means that targeted attacks could be highly effective when successful. The impact extends beyond simple execution of malicious code, as attackers could potentially leverage this vulnerability to establish persistent access or escalate privileges within the user's session. This vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as successful exploitation could enable attackers to execute arbitrary commands on the affected system.
Organizations should prioritize immediate remediation by updating to Adobe Dimension version 3.4.6 or later, which contains the necessary patches to address this out-of-bounds read vulnerability. Security teams should implement file validation procedures and user education initiatives to reduce the likelihood of successful exploitation attempts. Additionally, network monitoring should be enhanced to detect potential malicious file delivery attempts, and regular vulnerability scanning should be performed to identify any systems running vulnerable versions of the software. The patch addresses the root cause by implementing proper bounds checking during file parsing operations and ensuring that all memory accesses remain within allocated buffer boundaries.
