3 years ago Hey @mcgivrer sorry just jumping on this as well.
Seems like there have been more jetty fixes recently and the lastest patched version is 9.4.39.v20210325.
Are you able to update the PR to add this?
https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.39.v20210325
Thanks :)
Hello Here,
Using the SParkJava framwork for some personnal project, I detect the following security issue linked to SparkJava jetty usage, thanks to snyk.io.
High severity
Privilege Escalation
Affected module: org.eclipse.jetty:jetty-webapp@9.4.31.v20200723
Introduced through: com.sparkjava:spark-core@2.9.3
Exploit maturity: No known exploit
Fixed in: org.eclipse.jetty:jetty-webapp@9.4.33.v20201020, org.eclipse.jetty:jetty-webapp@jetty-10.0.0.beta3, org.eclipse.jetty:jetty-webapp@11.0.0.beta3
Detailed paths
Introduced through: com.sparkjava:spark-core@2.9.3 › org.eclipse.jetty:jetty-webapp@9.4.31.v20200723
Overview
org.eclipse.jetty:jetty-webapp is a maven plugin for Jetty web application support.
Affected versions of this package are vulnerable to Privilege Escalation. The system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.
Would you mind upgrading the underlaying jetty-webapp to org.eclipse.jetty:jetty-webapp@9.4.33.v20201020 ?
Thanks in advanced.
McG.
