Authentication Bypass by Spoofing vulnerability in Apache IoTDB. Certain Thrift RPC query handlers lack strict validation of the sessionId parameter. An attacker can construct requests with a forged sessionId and, without performing openSession authentication, receive valid query results. This allows authentication bypass and unauthorized reading of time-series data. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommend

apache iotdb UPGRADE

Affected: >= 1.3.3 and < 2.0.8

Fixed in: 2.0.8

Safe to downgrade to: a release before 1.3.3

1. Check installed version

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

2. UPGRADE to 2.0.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade iotdb

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 1.3.3 (Debian / Ubuntu)

apt-cache madison iotdb sudo apt install iotdb=<VERSION_BEFORE_1.3.3> sudo apt-mark hold iotdb

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

dnf --showduplicates list iotdb sudo dnf downgrade iotdb-<VERSION_BEFORE_1.3.3> sudo dnf versionlock add iotdb

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.
