CVE-2019-18643 is a critical-severity flaw (CVSS 9.8) affecting rock rms. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Rock RMS versions before 8.10 and versions 9.0 through 9.3 fails to properly validate files uploaded in the application. The only protection mechanism is a file-extension blacklist that can be bypassed by adding multiple spaces and periods after the file name. This could allow an attacker to upload ASPX code and gain remote code execution on the application. The application typically runs as LocalSystem as mandated in the installation guide. Patc

sparkdevnetwork rock rms UPGRADE

Affected: < 8.10 · >= 9.0 and < 9.4

Fixed in: 8.10, 9.4

Safe to downgrade to: a release before 9.0

1. Check installed version

apt-cache policy rock-rms || rpm -q rock-rms || rock-rms --version

2. UPGRADE to 8.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade rock-rms

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rock-rms

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 9.0 (Debian / Ubuntu)

apt-cache madison rock-rms sudo apt install rock-rms=<VERSION_BEFORE_9.0> sudo apt-mark hold rock-rms

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

dnf --showduplicates list rock-rms sudo dnf downgrade rock-rms-<VERSION_BEFORE_9.0> sudo dnf versionlock add rock-rms

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.
