Relative Path Traversal vulnerability in Apache Solr. Solr instances running on Windows are vulnerable to arbitrary filepath write-access, due to a lack of input-sanitation in the "configset upload" API. Commonly known as a "zipslip", maliciously constructed ZIP files can use relative filepaths to write data to unanticipated parts of the filesystem. This issue affects Apache Solr: from 6.6 through 9.7.0. Users are recommended to upgrade to v

apache solr UPGRADE

Affected: >= 6.6.0 and < 9.8.0

Fixed in: 9.8.0

Safe to downgrade to: a release before 6.6.0

1. Check installed version

apt-cache policy solr || rpm -q solr || solr --version

2. UPGRADE to 9.8.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade solr

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade solr

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.6.0 (Debian / Ubuntu)

apt-cache madison solr sudo apt install solr=<VERSION_BEFORE_6.6.0> sudo apt-mark hold solr

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list solr sudo dnf downgrade solr-<VERSION_BEFORE_6.6.0> sudo dnf versionlock add solr

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
