CVE-2020-15767 : Vulnerability Insights and Analysis

An issue was discovered in Gradle Enterprise before 2020.2.5 where the CSRF prevention token cookie lacks the 'secure' attribute, potentially enabling a CSRF attack.

Understanding CVE-2020-15767

This CVE highlights a security vulnerability in Gradle Enterprise that could be exploited by attackers to perform Cross-Site Request Forgery (CSRF) attacks.

What is CVE-2020-15767?

CVE-2020-15767 is a vulnerability in Gradle Enterprise that arises from the absence of the 'secure' attribute in the CSRF prevention token cookie, making it susceptible to interception by attackers conducting Man-in-the-Middle (MITM) attacks.

The Impact of CVE-2020-15767

The vulnerability allows attackers to potentially obtain the CSRF prevention token if a user mistakenly accesses the server via HTTP instead of HTTPS. This could lead to unauthorized actions being performed on behalf of the user through CSRF attacks.
