Fix not verifiedOdin Secure FTP <= 4.1 is vulnerable to a stack-based buffer overflow when parsing directory listings received in response to an FTP LIST command. A malicious FTP server can send an overly long filename in the directory listing, which overflows a fixed-size stack buffer in the client and overwrites the Structured Exception Handler (SEH). This allows remote attackers to execute arbitrary code on the client system.

A malicious FTP server can send an overly long filename in the directory listing, which overflows a fixed-size stack buffer in the client and overwrites the Structured Exception Handler (SEH). This allows remote attackers to execute arbitrary code on the client system.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
An attacker operating through a network path may attempt exploitation when the stated preconditions are met. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
CISA Vulnrichment records proof-of-concept exploitation in its SSVC data. BlackTree has not independently executed or validated exploit material.
CWE-121: Stack-based Buffer Overflow. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
