Description

Technical Field

[0001] This application relates to the field of databases, specifically to a method, apparatus, and device for preventing Redis injection in application systems. Background Technology

[0002] With the widespread use of Redis (an open-source, in-memory, key-value NoSQL database) as a high-performance key-value database in various application systems, its security issues have become increasingly prominent. Redis injection attacks refer to attackers constructing malicious input to influence Redis command execution logic or obtain sensitive data. Common attack methods include command separator injection, Lua script injection, and configuration keyword tampering. Currently, most application systems have significant shortcomings in Redis operation security protection.

[0003] Specifically, the problems are as follows: (1) Weak security protection: Most application systems do not perform security verification on Redis operations, developers lack professional protection knowledge, and there are obvious injection vulnerabilities in the code; (2) Incomplete protection measures: Even systems with protection measures often only target one type of attack (such as command separators) and do not cover multiple attack scenarios such as Lua script injection, configuration tampering, and key name pollution; (3) Lack of standardization and reusability: Each system implements protection logic independently, resulting in serious duplication of construction and inconsistent protection strategies, making it difficult to maintain and upgrade; (4) Insufficient scalability and flexibility: Existing solutions are difficult to flexibly adjust verification strategies according to business scenarios and cannot balance security and system performance.

[0004] Therefore, how to effectively prevent Redis injection in application systems has become an urgent problem to be solved. Summary of the Invention

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] In a first aspect, embodiments of this application provide a method for preventing Redis injection in application systems. Through multiple security verification mechanisms and flexible configuration strategies, a ready-to-use, highly secure anti-Redis injection component is achieved, supporting rapid integration and unified protection across various business systems.

[0021] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating the method for implementing Redis injection prevention in the application system according to this application. Figure 1 As shown, the methods for preventing Redis injection in application systems include: S1: Based on the Spring Boot technology stack, the anti-Redis injection function is encapsulated to obtain an anti-Redis injection component, which includes preset verification and interception mechanisms; S2: Obtain requests involving Redis operations, and verify and intercept the obtained requests through the anti-Redis injection component to achieve anti-Redis injection for the application system.

[0022] Furthermore, in one embodiment, an anti-Redis injection component is obtained by encapsulating the anti-Redis injection function based on the Spring Boot technology stack, specifically including: S101: Based on the SpringBoot (a rapid development scaffolding based on the Spring framework) technology stack, the anti-Redis injection function is encapsulated as an independent component, resulting in the anti-Redis injection component; S102: Package the anti-Redis injection component and upload it to a Maven private repository (local private repository server) or central repository; S103: The application system introduces the anti-Redis injection component through a dependency to enable the anti-Redis injection function.

[0023] Specifically, the process begins with component development. This can be done using Spring Boot to develop a Redis injection prevention component that integrates various validation and interception mechanisms. Then, the component is deployed by packaging the completed Redis injection prevention component and uploading it to a Maven private repository or central repository for use by various application systems. Finally, system integration is performed, with each application system importing the Redis injection prevention component as a dependency and enabling the protection function through annotations or configuration files.

[0024] Furthermore, in one embodiment, the verification and interception mechanism includes delimiter verification, Lua script verification, configuration keyword verification, and key name compliance verification.

[0025] Separator validation identifies and validates separators in the input content, including \r and \n separators; Lua script validation identifies and validates whether the input content contains Lua script keywords; configuration keyword validation identifies and validates whether the input content contains the keywords configParam (all dynamically modifiable configuration parameters in Redis) and requirepass (Redis global password authentication configuration item); key name compliance validation validates whether the input key (key name) contains the pattern (wildcard) keyword.

[0026] Furthermore, in one embodiment, see [reference needed].

If all validations pass, the request will be forwarded to the business logic execution.

[0027] Specifically, when a user initiates a request involving Redis operations, the anti-Redis injection component intercepts it through AOP aspects or interceptors, performing multiple checks in sequence, including separator verification, Lua script verification, configuration keyword verification, and key name compliance verification. If any check fails, the operation is blocked and a security exception is displayed. If all checks pass, the request is forwarded to the business logic for execution.

[0028] Furthermore, in one embodiment, the method for preventing Redis injection in an application system according to this application further includes: conducting security testing and performance evaluation based on actual business scenarios, and optimizing the verification rules in the verification and interception mechanisms. That is, conducting security testing and performance evaluation based on actual business scenarios, and optimizing verification strategies and configuration parameters.
