CVE-2017-2725 in P10
Summary
by MITRE
Bastet in P10 Plus and P10 smart phones with software Eariler than VKY-AL00C00B123 verisons,Earlier than VTR-AL00C00B123 versions have a buffer overflow vulnerability. An attacker with the root privilege of an Android system may trick a user into installing a malicious APP. The APP can modify specific data to cause buffer overflow in the next system reboot, causing continuous system reboot or arbitrary code execution.

The vulnerability identified as CVE-2017-2725 represents a critical buffer overflow flaw within the Bastet component of certain Huawei P10 Plus and P10 smartphone models. This vulnerability specifically affects devices running software versions earlier than VKY-AL00C00B123 and VTR-AL00C00B123, creating a persistent security risk that can be exploited through malicious application installation. The flaw resides in the system's handling of specific data modifications that occur during the boot process, making it particularly dangerous as it can trigger system instability and potentially enable arbitrary code execution. The vulnerability's impact extends beyond simple system crashes, as it can cause continuous reboot cycles that render devices unusable and potentially provide attackers with persistent access to compromised systems.
The technical implementation of this buffer overflow vulnerability stems from inadequate input validation within the Bastet service component that manages system boot processes. When a malicious application modifies specific system data structures, it can cause memory corruption during subsequent system reboots. This occurs because the system fails to properly bounds-check data inputs before processing them in memory buffers, allowing attackers to overwrite adjacent memory locations. The vulnerability aligns with CWE-121, which describes stack-based buffer overflow conditions, and represents a classic example of how improper memory management can lead to system compromise. The attack vector requires an attacker to already possess root privileges on the Android system, which means they can manipulate system-level components and install malicious applications that exploit this flaw.
The operational impact of CVE-2017-2725 extends beyond simple device instability, creating significant security implications for users and organizations relying on affected Huawei devices. The continuous reboot cycles can render devices completely unusable, while the potential for arbitrary code execution provides attackers with persistent access to compromised systems. This vulnerability particularly affects enterprise environments where mobile device management policies may not adequately address such low-level system exploits. The attack surface is further expanded by the fact that this vulnerability can be triggered through legitimate application installation processes, making it difficult for users to detect or prevent. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and persistence mechanisms, as attackers can leverage the system reboot process to maintain access to compromised devices.
Mitigation strategies for this vulnerability require immediate attention from device administrators and users. The primary recommendation involves updating affected Huawei devices to software versions that include patches for this buffer overflow flaw, specifically targeting the VKY-AL00C00B123 and VTR-AL00C00B123 releases or newer. Organizations should implement strict mobile device management policies that prevent installation of untrusted applications and maintain regular update schedules for all mobile devices. Security monitoring should include detection of unusual reboot patterns and system behavior that could indicate exploitation attempts. Additionally, users should be educated about the risks of installing applications from untrusted sources and the importance of keeping device software updated. The vulnerability demonstrates the critical importance of proper input validation and bounds checking in system-level components, as recommended by security standards and best practices for mobile device security.
