MEDIUM 6.1UPGRADE

CVE-2021-25938 is a medium-severity flaw (CVSS 6.1) affecting arangodb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In ArangoDB, versions v2.2.6.2 through v3.7.10 are vulnerable to Cross-Site Scripting (XSS), since there is no validation of the .zip file name and filtering of potential abusive characters which zip files can be named to. There is no X-Frame-Options Header set, which makes it more susceptible for leveraging self XSS by attackers.

Why this priority

Public exploit reference

A fixed release or distro patch exists.

arangodb arangodb UPGRADE

Affected: >= 2.2.6.2 and <= 3.7.10

Fixed in: newer than 3.7.10

Safe to downgrade to: a release before 2.2.6.2

1. Check installed version

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

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 2.2.6.2 (Debian / Ubuntu)

apt-cache madison arangodb sudo apt install arangodb=<VERSION_BEFORE_2.2.6.2> sudo apt-mark hold arangodb

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

dnf --showduplicates list arangodb sudo dnf downgrade arangodb-<VERSION_BEFORE_2.2.6.2> sudo dnf versionlock add arangodb

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.
