CVE-2023-25906 in Dimension
Summary
by MITRE • 03/28/2023
Adobe Dimension versions 3.4.7 (and earlier) 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 3.4.7 and earlier contains a critical out-of-bounds read vulnerability that stems from inadequate input validation during file parsing operations. This vulnerability falls under the CWE-125 weakness category, which specifically addresses out-of-bounds read conditions where a program attempts to access memory beyond the boundaries of a allocated buffer. The flaw manifests when the application processes a specially crafted file that triggers an improper memory access pattern, causing the software to read data from memory locations that were not intended to be accessed. The vulnerability is particularly dangerous because it can be leveraged by attackers to execute arbitrary code with the privileges of the currently logged-in user. The attack requires social engineering to convince the victim to open the malicious file, making it a user-interaction dependent exploit that aligns with ATT&CK technique T1204.202 for legitimate user execution. This vulnerability represents a significant risk to organizations as it can be exploited to gain unauthorized access to systems, potentially leading to complete system compromise and data exfiltration. The out-of-bounds read condition occurs during the parsing phase of the file processing pipeline, where the application fails to properly validate the size or structure of incoming data before attempting to access memory regions. This type of vulnerability is particularly concerning in creative software applications like Adobe Dimension, which frequently handle complex file formats and user-generated content. The memory corruption resulting from this flaw can be manipulated to overwrite critical program variables or execute malicious code sequences. The vulnerability's exploitation requires careful crafting of the malicious file to ensure that the out-of-bounds read triggers the desired execution flow, making it a sophisticated attack vector that requires understanding of both the application's memory management and the underlying operating system architecture. Security researchers have identified that this vulnerability can be effectively exploited through techniques such as return-oriented programming or stack pivoting to achieve code execution. Organizations using Adobe Dimension should prioritize immediate patching to mitigate this risk, as the vulnerability exists in a widely-used creative application that handles sensitive design and visual content from various sources. The attack surface is broad due to the nature of design applications that must process files from external sources, making this vulnerability particularly dangerous in enterprise environments where design assets are frequently shared across teams and departments. Adobe has addressed this issue in subsequent releases, and users should ensure they are running the latest version of the software to protect against this and similar memory corruption vulnerabilities.
The technical implementation of this vulnerability demonstrates how insufficient bounds checking in file parsing operations can lead to critical security flaws. When Adobe Dimension processes a crafted file, the application's memory management system fails to properly validate the boundaries of allocated memory structures before performing read operations. This type of vulnerability is classified as a memory safety issue that can result in unpredictable program behavior and potential code execution. The out-of-bounds read condition occurs because the application does not adequately verify that the data being read from the malicious file does not exceed the allocated buffer size. This allows an attacker to craft a file that, when opened, causes the application to access memory locations beyond the intended buffer boundaries. The vulnerability is particularly dangerous because it can be exploited to achieve arbitrary code execution, which is a fundamental attack pattern that can lead to complete system compromise. The requirement for user interaction makes this vulnerability somewhat less severe than fully autonomous exploits, but it still represents a significant threat vector in environments where users frequently handle files from untrusted sources. The exploitation process involves carefully constructing the malicious file to trigger the memory access violation in a way that can be controlled to execute attacker-supplied code. This attack vector aligns with common exploitation techniques found in the ATT&CK framework under the execution and privilege escalation categories. The vulnerability's impact is amplified by the fact that Adobe Dimension is commonly used in professional environments where users regularly open files from various sources, increasing the likelihood of successful exploitation. Security professionals should monitor for indicators of compromise related to this vulnerability and ensure that all instances of the affected software are updated to the latest patched versions to prevent potential exploitation attempts. The vulnerability's presence in a creative application also highlights the importance of considering file format security in all software applications that process external content, regardless of their primary function or target audience.
