CVE-2020-15250 – Information disclosure in JUnit4

https://notcve.org/view.php?id=CVE-2020-15250

In JUnit4 from version 4.7 and before 4.13.1, the test rule TemporaryFolder contains a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users to overwrite the contents of these directories or files. This is purely an information disclosure vulnerability. • https://github.com/junit-team/junit4/blob/7852b90cfe1cea1e0cdaa19d490c83f0d8684b50/doc/ReleaseNotes4.13.1.md https://github.com/junit-team/junit4/commit/610155b8c22138329f0723eec22521627dbc52ae https://github.com/junit-team/junit4/issues/1676 https://github.com/junit-team/junit4/security/advisories/GHSA-269g-pwp5-87pp https://junit.org/junit4/javadoc/4.13/org/junit/rules/TemporaryFolder.html https://lists.apache.org/thread.html/r01110833b63616ddbef59ae4e10c0fbd0060f0a51206defd4cb4d917%40%3Ccommits.pulsar.apache.org%3E https://li • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-732: Incorrect Permission Assignment for Critical Resource •
