CVE-2019-3797 : Vulnerability Insights and Analysis

This CVE involves a vulnerability in Spring Data JPA that affects versions up to and including 2.1.5, 2.0.13, and 1.11.19. The issue arises when using certain predicates in derived queries, potentially leading to unexpected results due to manipulated query parameter values.

Understanding CVE-2019-3797

This vulnerability exposes additional information when utilizing Spring Data JPA derived queries.

What is CVE-2019-3797?

The vulnerability in Spring Data JPA versions allows for the exposure of extra information through derived queries, potentially leading to unexpected outcomes.

The Impact of CVE-2019-3797

The vulnerability can result in more results than expected when specific predicates are used in derived queries, and LIKE expressions in manual queries may produce unexpected outcomes if parameter values are not properly handled.

Technical Details of CVE-2019-3797

This section provides technical insights into the CVE.

Vulnerability Description

The vulnerability in Spring Data JPA versions up to 2.1.5, 2.0.13, and 1.11.19 can lead to additional information exposure when using certain predicates in derived queries.

Affected Systems and Versions

Spring Data JPA versions up to and including 2.1.5, 2.0.13, and 1.11.19

Exploitation Mechanism
