CVE-2020-9257
Description
HUAWEI P30 Pro smartphones with versions earlier than 10.1.0.123(C432E19R2P5patch02), versions earlier than 10.1.0.126(C10E11R5P1), and versions earlier than 10.1.0.160(C00E160R2P8) have a buffer overflow vulnerability. The software access data past the end, or before the beginning, of the intended buffer when handling certain operations of certificate, the attacker should trick the user into installing a malicious application, successful exploit may cause code execution.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Unauthenticated remote attackers can exploit a buffer overflow in Huawei P30 Pro certificate handling to achieve arbitrary code execution.
Vulnerability
HUAWEI P30 Pro smartphones running versions earlier than 10.1.0.123(C432E19R2P5patch02), 10.1.0.126(C10E11R5P1), or 10.1.0.160(C00E160R2P8) contain a buffer overflow vulnerability. The flaw exists in the certificate handling process, where the software accesses data beyond the intended buffer boundaries. An attacker must trick the user into installing a malicious application to reach the vulnerable code path. [1]
Exploitation
Exploitation requires social engineering to persuade the user to install a crafted application on the device. No other user interaction or special privileges are needed once the application is installed. The application triggers the buffer overflow by sending specially crafted certificate operations to the vulnerable handler. [1]
Impact
Successful exploitation leads to arbitrary code execution on the target device. The attacker gains the ability to execute code at the privilege level of the affected process, which could allow full compromise of the device. [1]
Mitigation
Huawei released software updates to fix this vulnerability. Users should update to the resolved versions: 10.1.0.123(C432E19R2P5patch02), 10.1.0.126(C10E11R5P1), or 10.1.0.160(C00E160R2P8), depending on their specific device variant. The security advisory was published on 2020-07-15. No workarounds are provided; applying the patch is the recommended mitigation. [1]
