twiki twiki UPGRADE

Affected: >= 4.0 and <= 4.0.5 · >= 4.1 and <= 4.1.2 · >= 4.2 and <= 4.2.4 · >= 4.3 and <= 4.3.2 · >= 5.0 and <= 5.0.2 · >= 5.1.0 and <= 5.1.4 · 6.0

Fixed in: newer than 5.1.4

Safe to downgrade to: a release before 4.0

1. Check installed version

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

2. UPGRADE to newer than 5.1.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade twiki

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 4.0 (Debian / Ubuntu)

apt-cache madison twiki sudo apt install twiki=<VERSION_BEFORE_4.0> sudo apt-mark hold twiki

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

dnf --showduplicates list twiki sudo dnf downgrade twiki-<VERSION_BEFORE_4.0> sudo dnf versionlock add twiki

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.

Public exploits and detection

Public code exists for this CVE. Treat unpatched systems as at risk, and only run PoCs in a lab.
