Intelligent Management Center (iMC): Deserialization of Untrusted Data
CVE-2024-13980 is a critical-severity deserialization of untrusted data vulnerability in Intelligent Management Center (iMC) from H3C Group, with a CVSS 4.0 base score of 10.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Intelligent Management Center (iMC) versions: E0632H07 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.97% chance of exploitation within 30 days, higher than 62% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Intelligent Management Center (iMC) you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on h3c.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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.

The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
