CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
A stack-based buffer overflow in the devices Telnet/SSH CLI login routine occurs when a unauthenticated attacker send an oversized or unexpected username input. An overflow condition crashes the thread handling the login attempt, forcing the session to close. Because other CLI sessions remain unaffected, the impact is limited to a low‑severity availability disruption.
