CVE-2020-2244: 
Java vulnerability analysis and mitigation

CVE-2020-2244 is a cross-site scripting (XSS) vulnerability discovered in the Jenkins Build Failure Analyzer Plugin versions 1.27.0 and earlier. The vulnerability was disclosed on September 1, 2020, affecting the plugin's form validation response functionality (Jenkins Advisory).

The vulnerability exists because the Build Failure Analyzer Plugin does not properly escape matching text in form validation responses. This creates a cross-site scripting (XSS) vulnerability that can be exploited by attackers who are able to provide console output for builds used to test build log indications. The severity of this vulnerability is rated as High according to the CVSS scoring system (Jenkins Advisory).

The vulnerability allows attackers who can provide console output for builds to execute cross-site scripting attacks through the build log indications testing functionality. This could potentially lead to unauthorized access to sensitive information or execution of malicious code in the context of other users' browsers (Jenkins Advisory).

The vulnerability is exploitable by attackers who have the ability to provide console output for builds that are used in testing build log indications. This requires specific access permissions within the Jenkins environment (Jenkins Advisory).

The vulnerability has been fixed in Build Failure Analyzer Plugin version 1.27.1, which properly escapes matching text in the affected form validation response. Users are strongly advised to upgrade to this version to mitigate the security risk (Jenkins Advisory).
