CVE-2023-32831
Description
In wlan driver, there is a possible PIN crack due to use of insufficiently random values. This could lead to local information disclosure with no execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00325055; Issue ID: MSV-868.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Insufficient randomness in MediaTek wlan driver PIN generation allows local attackers to crack the PIN, leading to information disclosure.
Vulnerability
The wlan driver on affected MediaTek chipsets uses insufficiently random values when generating PINs. This vulnerability (CVE-2023-32831) allows an attacker to predict or brute-force the PIN. The issue is present in the wlan driver code and affects multiple chipsets as listed in the MediaTek January 2024 security bulletin [1]. The patch ID is WCNCR00325055.
Exploitation
An attacker with local access to the device (no execution privileges required) can exploit this vulnerability without any user interaction. By observing or intercepting the PIN generation process, the attacker can leverage the weak randomness to crack the PIN.
Impact
Successful exploitation leads to local information disclosure. The attacker can obtain the PIN, potentially compromising Wi-Fi credentials or other sensitive data protected by the PIN.
Mitigation
MediaTek has released a security patch in the January 2024 bulletin [1]. Device OEMs have been notified and are expected to deploy the fix. Users should apply the latest firmware updates from their device manufacturer.
