CRITICAL 9.0REMOTEUPGRADE

CVE-2022-41989 is a critical-severity flaw (CVSS 9.0) affecting real-time location system studio. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Sewio’s Real-Time Location System (RTLS) Studio version 2.0.0 up to and including version 2.6.2 does not validate the length of RTLS report payloads during communication. This allows an attacker to send an exceedingly long payload, resulting in an out-of-bounds write to cause a denial-of-service condition or code execution.

sewio real-time location system studio UPGRADE

Affected: >= 2.0.0. and <= 2.6.2

Fixed in: newer than 2.6.2

Safe to downgrade to: a release before 2.0.0.

1. Check installed version

apt-cache policy real-time-location-system-studio || rpm -q real-time-location-system-studio || real-time-location-system-studio --version

2. UPGRADE to newer than 2.6.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade real-time-location-system-studio

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade real-time-location-system-studio

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 2.0.0. (Debian / Ubuntu)

apt-cache madison real-time-location-system-studio sudo apt install real-time-location-system-studio=<VERSION_BEFORE_2.0.0.> sudo apt-mark hold real-time-location-system-studio

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

dnf --showduplicates list real-time-location-system-studio sudo dnf downgrade real-time-location-system-studio-<VERSION_BEFORE_2.0.0.> sudo dnf versionlock add real-time-location-system-studio

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.
