HIGH 8.1REMOTEUPGRADE

CVE-2020-5411 is a high-severity flaw (CVSS 8.1) affecting spring batch. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

When configured to enable default typing, Jackson contained a deserialization vulnerability that could lead to arbitrary code execution. Jackson fixed this vulnerability by blacklisting known "deserialization gadgets". Spring Batch configures Jackson with global default typing enabled which means that through the previous exploit, arbitrary code could be executed if all of the following is true: * Spring Batch's Jackson support is being leveraged

broadcom spring batch UPGRADE

Affected: >= 4.0.0 and <= 4.0.4 · >= 4.1.0 and <= 4.1.4 · >= 4.2.0 and <= 4.2.2

Fixed in: newer than 4.2.2

Safe to downgrade to: a release before 4.0.0

1. Check installed version

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

2. UPGRADE to newer than 4.2.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-batch

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 4.0.0 (Debian / Ubuntu)

apt-cache madison spring-batch sudo apt install spring-batch=<VERSION_BEFORE_4.0.0> sudo apt-mark hold spring-batch

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

dnf --showduplicates list spring-batch sudo dnf downgrade spring-batch-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add spring-batch

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.
