Vulnerability Exploitation for Device Patching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex ecosystem of modern mobile devices, involving multiple parties, often leads to slow and ineffective vulnerability patching due to disorganization and lack of incentives, resulting in unresolved security flaws.
Innovation Solution
A system comprising a vulnerability tool with an assessment component, exploit engine, and update component that identifies and exploits vulnerabilities to grant escalated privileges, enabling the application of patches through a reference monitor, even in closed systems where necessary privileges are absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional multi-party ecosystem approach is used for vulnerability patching, then device security coverage is comprehensive, but the patching speed becomes extremely slow and vulnerabilities remain unresolved
Solution Approach 1:
The patent converts the identified vulnerability from a harmful security flaw into a beneficial mechanism for privilege escalation. By exploiting the vulnerability through controlled means, the system gains the necessary privileges to apply patches that would otherwise be inaccessible, thus transforming the security risk into a patching opportunity.
Solution Approach 2:
Instead of following the conventional top-down patching approach where privileged parties distribute updates, the patent inverts the process by using vulnerability exploitation from the bottom up to gain privileges. This reverse approach allows the patching mechanism to work against the grain of the traditional security model, enabling updates without relying on the cooperation of multiple ecosystem parties.
2Reliability
If privileged parties control the patching process, then system security is maintained, but patching becomes ineffective when parties lack incentives
Solution Approach 1:
The patent enables the device to perform self-patching by automatically exploiting its own vulnerabilities to gain the necessary privileges. This self-service mechanism eliminates the dependency on external privileged parties who may lack incentives, allowing the system to patch itself autonomously without human intervention or coordination with ecosystem stakeholders.
Solution Approach 2:
The patent introduces a reference monitor as an intermediary component that mediates between the vulnerability exploitation process and the patching mechanism. This intermediary ensures that the exploitation is controlled and safe, while still enabling the necessary privilege escalation to apply patches, thus maintaining security while improving effectiveness.
3Ease of operation
If exploitation is used to gain privileges, then patching access is enabled, but the system complexity increases
Solution Approach 1:
The patent extracts the patching functionality from the privileged domain and makes it accessible through the unprivileged user space by utilizing vulnerability exploitation. This separation allows the complex privilege escalation logic to be isolated from the core patching mechanism, enabling patching access without permanently increasing system complexity.
Solution Approach 2:
The patent performs preliminary vulnerability assessment and exploitation preparation before the actual patching process. By pre-identifying exploitable vulnerabilities and preparing the exploitation payload in advance, the system reduces the complexity of the real-time patching operation, making the overall process more manageable and less intrusive.
Data Source
AI summary
A system and method that includes identifying a vulnerability in a computing device; accessing a vulnerability exploitation mapped to the identified vulnerability; at the computing device, executing the vulnerability exploitation and entering an operating mode of escalated privileges; and while in the operating mode of escalated privileges, updating the system with a vulnerability resolution.
