CVE-2026-67246 in ADM
Summary
by MITRE • 07/30/2026
A path traversal vulnerability was found in the Wallpaper component of ADM. The vulnerability occurs because user-controlled wallpaper path input is not sufficiently validated before being used for file access. An authenticated attacker can exploit this issue to access or manipulate files outside the intended wallpaper directory, subject to user permissions and filesystem restrictions. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.

This path traversal vulnerability in the Wallpaper component of ADM represents a critical security weakness that allows authenticated attackers to bypass intended file access controls and potentially gain unauthorized access to sensitive system files. The flaw stems from insufficient validation of user-controlled input parameters that specify wallpaper paths, creating an opportunity for malicious actors to manipulate file system access through carefully crafted directory traversal sequences. The vulnerability affects multiple version ranges including ADM 4.1.0 through 4.3.3.RUN1 and ADM 5.0.0 through 5.1.3.RI81, indicating a widespread issue that spans several major releases and suggests the problem has persisted across development cycles.
The technical implementation of this vulnerability aligns with common path traversal patterns where user-supplied data directly influences file system operations without proper sanitization or validation. When an authenticated user provides a wallpaper path input, the system processes this input without adequate checks to ensure it remains within the designated wallpaper directory boundaries. This allows attackers to construct malicious paths using sequences such as "../" or similar directory navigation patterns that can traverse up the file system hierarchy and access files outside the intended scope of wallpaper management functionality.
From an operational impact perspective, this vulnerability creates significant risk for organizations relying on ADM systems, as authenticated attackers can potentially access sensitive configuration files, log data, or other system resources that should remain protected. The scope of exploitation is limited by user permissions and underlying filesystem restrictions, but the potential for privilege escalation or information disclosure remains substantial. Attackers could leverage this vulnerability to gather intelligence about system configurations, access restricted files, or even manipulate critical system components through carefully selected file operations within the wallpaper management context.
The mitigation strategies for this vulnerability should prioritize immediate implementation of input validation mechanisms that strictly enforce path boundaries and prevent directory traversal sequences from being processed. Organizations should implement proper path normalization techniques, employ whitelist validation for acceptable file paths, and ensure that all user-controlled inputs undergo rigorous sanitization before any file system operations occur. Additionally, regular security audits and code reviews should be conducted to identify similar patterns in other components of the ADM system. This vulnerability demonstrates the importance of following secure coding practices and adheres to principles outlined in CWE 22 Path Traversal and ATT&CK techniques related to privilege escalation through file system manipulation. The affected versions suggest that this issue requires immediate attention from system administrators who should upgrade to patched releases or implement compensating controls until full remediation is achieved.
