Medium 5.9
Published
Updated
Check this codebase for CVE-2019-12384 and fix it if it is affected.
What it is: CVE-2019-12384 is a medium-severity unsafe deserialization vulnerability in Debian Debian Linux, published on 24 Jun 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-12384 in the wild and no public exploit code.
Affected packages and fixed versions:
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.0.0; fixed in 2.6.7.3
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.0.0; fixed in 2.6.7.3
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.7.0; fixed in 2.7.9.6
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.7.0; fixed in 2.7.9.6
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.8.0; fixed in 2.8.11.4
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.8.0; fixed in 2.8.11.4
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.9.0; fixed in 2.9.9.1
- com.fasterxml.jackson.core:jackson-databind (Maven): affected from 2.9.0; fixed in 2.9.9.1
Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.

What is CVE-2019-12384?
CVE-2019-12384 is a medium-severity unsafe deserialization vulnerability in Debian Debian Linux, published on 24 Jun 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible.
Weakness: CWE-502
