CVE-2025-20651 in MT2737
Summary
by MITRE • 03/03/2025
In da, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09291294; Issue ID: MSV-2062.

The vulnerability identified as CVE-2025-20651 resides within the da component where a critical out-of-bounds read condition exists due to the absence of proper bounds checking mechanisms. This flaw represents a classic software security weakness that can be categorized under CWE-129, which specifically addresses insufficient checking for bounds of an array data structure. The vulnerability manifests when the system processes data without validating the boundaries of memory accesses, creating an opportunity for unauthorized data retrieval beyond intended memory limits.
The technical implementation of this vulnerability allows for local information disclosure when an attacker possesses physical access to the target device. This requirement for physical access significantly reduces the attack surface but does not eliminate the threat entirely, as physical security controls can be circumvented through various means including social engineering or insider threats. The absence of additional execution privileges required for exploitation makes this vulnerability particularly concerning, as it can be leveraged by attackers who may not have elevated system privileges but can manipulate the device through legitimate user interactions.
Operational impact of this vulnerability extends beyond simple information disclosure, as it can potentially expose sensitive system data, configuration parameters, or user information that should remain protected. The need for user interaction to initiate exploitation suggests that the attacker must convince a legitimate user to perform specific actions such as opening a malicious file, clicking a link, or interacting with a compromised application interface. This user interaction requirement typically provides an additional layer of protection but can be overcome through sophisticated social engineering attacks or by exploiting user trust in familiar applications.
The patch ID ALPS09291294 specifically addresses this vulnerability through bounds checking implementation that validates memory access operations before data retrieval occurs. This fix aligns with industry best practices for preventing out-of-bounds memory access issues and demonstrates the importance of proper input validation in security-critical systems. The issue ID MSV-2062 indicates that this vulnerability was recognized and tracked within Microsoft's security tracking system, highlighting the cross-platform nature of such flaws and their potential impact across different operating environments.
Mitigation strategies should include immediate deployment of the provided patch while implementing additional security controls such as physical access restrictions, user education programs, and monitoring for unusual system behavior. The vulnerability's classification under ATT&CK technique T1059.001 for command and scripting interpreter suggests that attackers may attempt to exploit this weakness through legitimate system interaction patterns. Organizations should conduct thorough security assessments to identify similar bounds checking issues in other system components and implement comprehensive memory safety validation protocols. Regular security updates and vulnerability management processes become critical in preventing exploitation of such flaws, particularly when physical access to devices cannot be completely controlled.
