Google Android WLAN input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in Google Android (Smartphone Operating System) (affected version unknown). It has been rated as critical. This issue affects an unknown functionality of the component WLAN Handler. 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. The summary by CVE is:

In all android releases(Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, WLAN handler indication from the firmware gets the information for 4 access categories. While processing this information only the first 3 AC information is copied due to the improper conditional logic used to compare with the max number of categories.

The bug was discovered 09/05/2018. The weakness was released 09/18/2018 (Website). The advisory is shared at source.codeaurora.org. The identification of this vulnerability is CVE-2018-11294 since 05/18/2018. The exploitation is known to be easy. The attack can only be done within the local network. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 05/16/2023). 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 13 days. During that time the estimated underground price was around $25k-$100k.

Applying a patch is able to eliminate this problem.
