MEDIUM 4.9UPGRADEUPGRADEUPGRADE

CVE-2024-8995 is a medium-severity flaw (CVSS 4.9) affecting api control plane, api manager, identity server. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused. If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead

wso2 api control plane UPGRADE

Affected: >= 4.5.0 and < 4.5.0.56 · >= 4.6.0 and < 4.6.0.20

Fixed in: 4.5.0.56, 4.6.0.20

Safe to downgrade to: a release before 4.5.0

1. Check installed version

apt-cache policy api-control-plane || rpm -q api-control-plane || api-control-plane --version

2. UPGRADE to 4.5.0.56 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade api-control-plane

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade api-control-plane

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 4.5.0 (Debian / Ubuntu)

apt-cache madison api-control-plane sudo apt install api-control-plane=<VERSION_BEFORE_4.5.0> sudo apt-mark hold api-control-plane

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

dnf --showduplicates list api-control-plane sudo dnf downgrade api-control-plane-<VERSION_BEFORE_4.5.0> sudo dnf versionlock add api-control-plane

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.
