The Live Auction Cockpit in SAP Supplier Relationship Management (SRM) uses a deprecated java applet component, which allows an unauthenticated attacker to send malicious payload request in a specific encoding format. The servlet will then decode this malicious request which will result in deserialization of data in the application leading to execution of arbitrary OS command on target as SAP Administrator. This vulnerability has High impact on confidentiality, integrity, and availability of the application.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Supplier_relationship_management | Sap | 7.14 (including) | 7.14 (including) |
Potential Mitigations
- Make fields transient to protect them from deserialization.
- An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
