CVE-2020-5398 is a high-severity flaw (CVSS 7.5) affecting spring framework, application testing suite, communications billing and revenue management elastic charging engine. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In Spring Framework, versions 5.2.x prior to 5.2.3, versions 5.1.x prior to 5.1.13, and versions 5.0.x prior to 5.0.16, an application is vulnerable to a reflected file download (RFD) attack when it sets a "Content-Disposition" header in the response where the filename attribute is derived from user supplied input.

vmware spring framework UPGRADE

Affected: >= 5.0.0 and < 5.0.16 · >= 5.1.0 and < 5.1.13 · >= 5.2.0 and < 5.2.3

Fixed in: 5.0.16, 5.1.13, 5.2.3

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy spring-framework || rpm -q spring-framework || spring-framework --version

2. UPGRADE to 5.0.16 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-framework

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-framework

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 5.0.0 (Debian / Ubuntu)

apt-cache madison spring-framework sudo apt install spring-framework=<VERSION_BEFORE_5.0.0> sudo apt-mark hold spring-framework

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

dnf --showduplicates list spring-framework sudo dnf downgrade spring-framework-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add spring-framework

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.
