Remote Command Execution in SOFARPC
CVE-2024-23636 · GHSA-7q8p-9953-pxvr
- Affected
- Maven com.alipay.sofa:rpc-sofa-boot-starter < 5.12.0
- Fixed in
- 5.12.0· Vendor fix available
- Issue
- Impact SOFARPC defaults to using the SOFA Hessian protocol to deserialize received data, while the SOFA Hessian protocol uses a blacklist mechanism to restrict deserialization of potentially dangerous classes for security protection. But there is a gadget chain that can bypass the SOFA Hessian blacklist protection mechanism, and this gadget chain only relies on JDK and does not rely on any third-party components. Patches Fixed this issue by adding a blacklist, users can upgrade to sofarpc version 5.12.0 to avoid this issue. Workarounds SOFARPC also provides a way to add additional blacklist. Users can add some class like -Drpcserializeblacklistoverride=org.apache.xpath. to avoid this issue.
Recommended action: Upgrade to 5.12.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
