Routine

MEDIUM 6.1UPGRADE

CVE-2023-50069 is a medium-severity flaw (CVSS 6.1) affecting wiremock. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

WireMock with GUI versions 3.2.0.0 through 3.0.4.0 are vulnerable to stored cross-site scripting (SXSS) through the recording feature. An attacker can host a malicious payload and perform a test mapping pointing to the attacker's file, and the result will render on the Matched page in the Body area, resulting in the execution of the payload. This occurs because the response body is not validated or sanitized.

wiremock wiremock UPGRADE

Affected: >= 3.0.4 and <= 3.2.0

Fixed in: newer than 3.2.0

Safe to downgrade to: a release before 3.0.4

1. Check installed version

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

2. UPGRADE to newer than 3.2.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wiremock

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 3.0.4 (Debian / Ubuntu)

apt-cache madison wiremock sudo apt install wiremock=<VERSION_BEFORE_3.0.4> sudo apt-mark hold wiremock

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

dnf --showduplicates list wiremock sudo dnf downgrade wiremock-<VERSION_BEFORE_3.0.4> sudo dnf versionlock add wiremock

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.
