CVE-2021-25992 is a critical-severity flaw (CVSS 9.8) affecting ifme. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In Ifme, versions 1.0.0 to v.7.33.2 don’t properly invalidate a user’s session even after the user initiated logout. It makes it possible for an attacker to reuse the admin cookies either via local/network access or by other hypothetical attacks.

if-me ifme UPGRADE

Affected: >= 1.0.0 and <= 7.33.2

Fixed in: newer than 7.33.2

Safe to downgrade to: a release before 1.0.0

1. Check installed version

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

2. UPGRADE to newer than 7.33.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ifme

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 1.0.0 (Debian / Ubuntu)

apt-cache madison ifme sudo apt install ifme=<VERSION_BEFORE_1.0.0> sudo apt-mark hold ifme

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

dnf --showduplicates list ifme sudo dnf downgrade ifme-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add ifme

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.
