Advisory generated from the CVE record, CISA, Exploit Observer and VEDAS: what it is, whether it is exploited, who is affected, and how to fix and detect it.
Generated by VEDAS. Scores as of 2026-11-01 19:19 UTC. Rebuilt every few hours from cve-scores, CISA KEV and vedas-signatures. How this works and its limits.
What it is
An issue was discovered in Lantronix EDS5000 2.1.0.0R3. The HTTP RPC module executes a shell command to write logs when user’s authentication fails. The username is directly concatenated with the command without any sanitization. This allow attackers to inject arbitrary OS commands into the username parameter. Injected commands are executed with root privileges.
