CVE-2025-15607 in AX53
Summary
by MITRE • 03/20/2026
A command injection vulnerability on AX53 v1 occurs in mscd debug functionality due to insufficient input handling, allowing log redirection to arbitrary files and concatenation of unvalidated file content into shell commands, enabling authenticated attackers to inject and execute arbitrary commands. Successful exploitation may allow execution of malicious commands and ultimately full control of the device.

The command injection vulnerability identified as CVE-2025-15607 affects the AX53 v1 device within its mscd debug functionality, representing a critical security flaw that undermines the device's operational integrity. This vulnerability stems from inadequate input validation mechanisms that fail to properly sanitize user-supplied data before processing. The flaw specifically manifests when the system attempts to handle log redirection requests, where unvalidated file paths and content are directly concatenated into shell commands without proper sanitization or verification.
The technical exploitation of this vulnerability occurs through authenticated access to the device's debug interface, where attackers can manipulate input parameters to redirect logging operations to arbitrary file locations. The insufficient input handling allows malicious actors to inject shell commands that are subsequently executed with the privileges of the affected service. This type of vulnerability maps directly to CWE-77 which classifies command injection flaws where untrusted data is incorporated into shell commands without proper validation or sanitization. The vulnerability operates at the intersection of improper input validation and shell command construction, creating a pathway for arbitrary code execution.
From an operational impact perspective, successful exploitation of CVE-2025-15607 grants attackers full control over the affected AX53 v1 device, enabling them to execute malicious commands with elevated privileges. This complete compromise allows for persistent access, data exfiltration, and potential lateral movement within network environments where the device resides. The vulnerability's authenticated nature requires initial access credentials but once exploited, provides attackers with unrestricted control over the device's functionality, including potential access to sensitive network information and system resources.
Security professionals should implement immediate mitigations including input validation controls that sanitize all user-supplied data before processing, particularly within debug and logging functionalities. Network segmentation and access control measures should be enforced to limit authentication attempts and reduce the attack surface. Regular firmware updates and security patches should be deployed immediately upon availability, while monitoring systems should be configured to detect anomalous command execution patterns. The vulnerability aligns with ATT&CK technique T1059.001 for command and script injection, making it a significant concern for defensive security operations that must account for both authenticated and unauthenticated attack vectors. Organizations should also consider implementing principle of least privilege access controls and regular security assessments to identify similar vulnerabilities in network infrastructure devices.
