HIGH 7.5REMOTEUPGRADE

CVE-2022-25377 is a high-severity flaw (CVSS 7.5) affecting appwrite. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, APP_STORAGE_CERTIFICATES/.well-known/acme-challenge must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)

appwrite appwrite UPGRADE

Affected: >= 0.5.0 and < 0.12.2

Fixed in: 0.12.2

Safe to downgrade to: a release before 0.5.0

1. Check installed version

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

2. UPGRADE to 0.12.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade appwrite

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 0.5.0 (Debian / Ubuntu)

apt-cache madison appwrite sudo apt install appwrite=<VERSION_BEFORE_0.5.0> sudo apt-mark hold appwrite

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

dnf --showduplicates list appwrite sudo dnf downgrade appwrite-<VERSION_BEFORE_0.5.0> sudo dnf versionlock add appwrite

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.
