CVE-2024-30212

Public exploitAvailableProof of concept on GitHub (unverified)

If a SCSI READ(10) command is initiated via USB using the largest LBA (0xFFFFFFFF) with it's default block size of 512 and a count of 1,

the first 512 byte of the 0x80000000 memory area is returned to the user. If the block count is increased, the full RAM can be exposed.

The same method works to write to this memory area. If RAM contains pointers, those can be - depending on the application - overwritten to

return data from any other offset including Progam and Boot Flash.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
