paloaltonetworks cortex xsoar UPGRADE

Affected: >= 8.10.0 and < 8.13.0.11

Fixed in: 8.13.0.11

Safe to downgrade to: a release before 8.10.0

1. Check installed version

apt-cache policy cortex-xsoar || rpm -q cortex-xsoar || cortex-xsoar --version

2. UPGRADE to 8.13.0.11 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade cortex-xsoar

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cortex-xsoar

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 8.10.0 (Debian / Ubuntu)

apt-cache madison cortex-xsoar sudo apt install cortex-xsoar=<VERSION_BEFORE_8.10.0> sudo apt-mark hold cortex-xsoar

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

dnf --showduplicates list cortex-xsoar sudo dnf downgrade cortex-xsoar-<VERSION_BEFORE_8.10.0> sudo dnf versionlock add cortex-xsoar

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.
