Deserialization of Untrusted Data in Apache Olingo
CVE-2019-17556 · GHSA-gj76-429m-56wc
- Affected
- Maven org.apache.olingo:odata-client-proxy >= 4.0.0, <= 4.6.0
- Fixed in
- 4.7.0· Vendor fix available
- Issue
- Apache Olingo versions 4.0.0 to 4.6.0 provide the AbstractService class, which is public API, uses ObjectInputStream and doesn't check classes being deserialized. If an attacker can feed malicious metadata to the class, then it may result in running attacker's code in the worse case.
Recommended action: Upgrade to 4.7.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
