What it is: CVE-2017-2582 is a medium-severity vulnerability in Redhat Jboss Enterprise Application Platform, published on 26 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-2582 in the wild and no public exploit code.
Affected packages and fixed versions:

- org.keycloak:keycloak-core (Maven): affected all versions; fixed in 2.5.1
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-2017-2582?
CVE-2017-2582 is a medium-severity vulnerability in Redhat Jboss Enterprise Application Platform, published on 26 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
It was found that while parsing the SAML messages the StaxParserUtil class of keycloak before 2.5.1 replaces special strings for obtaining attribute values with system property. This could allow an attacker to determine values of system properties at the attacked system by formatting the SAML request ID field to be the chosen system property which could be obtained in the "InResponseTo" field in the response.
