Detailsinfo

A vulnerability was found in Google Android (Smartphone Operating System) (the affected version unknown). It has been rated as critical. Affected by this issue is an unknown part of the component Qualcomm. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In all Qualcomm products with Android releases from CAF using the Linux kernel, when an access point sends a challenge text greater than 128 bytes, the host driver is unable to validate this potentially leading to authentication failure.

The bug was discovered 02/05/2018. The weakness was disclosed 02/23/2018 (Website). The advisory is shared for download at source.android.com. This vulnerability is handled as CVE-2017-15817 since 10/24/2017. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 01/08/2020). It is expected to see the exploit prices for this product increasing in the near future.

The vulnerability was handled as a non-public zero-day exploit for at least 18 days. During that time the estimated underground price was around $5k-$25k.

Applying a patch is able to eliminate this problem.
