CVE-2024-13980

H3C Intelligent Management Center (IMC) versions up to and including E0632H07 contains a remote command execution vulnerability in the /byod/index.xhtml endpoint. Improper handling of JSF ViewState allows unauthenticated attackers to craft POST requests with forged javax.faces.ViewState parameters, potentially leading to arbitrary command execution. This flaw does not require authentication and may be exploited without session cookies. An affected version range is undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-08-28 UTC.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

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.
