The TFTP server in PacketTrap pt360 Tool Suite PRO 2.0.3901.0 and earlier allows remote attackers to cause a denial of service (daemon hang) by uploading a file named (1) '|' (pipe), (2) '"' (quotation mark), or (3) "<>" (less than, greater than); or (4) a file with a long name. NOTE: the issue for vector 4 might exist because of an incomplete fix for CVE-2008-1312.

→Monitor TFTP WRQ (write request) packets containing special characters in the filename field: pipe '|', double-quote '"', or angle brackets '<>' — any of these sent to a PacketTrap TFTP server will trigger a daemon hang. ↗
→Detect TFTP WRQ packets with abnormally long filenames, which may indicate exploitation of the long-name DoS vector (related to incomplete fix for CVE-2008-1312). ↗
→The exploit uses Net::TFTP in ASCII mode to PUT a file with a malicious name (e.g. '|') to the target; detect TFTP write requests in netflow/packet capture where the filename field contains shell metacharacters. ↗
→A Metasploit auxiliary module exists for this vulnerability targeting PacketTrap TFTP Server 2.2.5459.0; presence of this module's traffic pattern (TFTP WRQ with special filename) should be flagged. ↗

·The IP address 192.168.0.112 in the PoC exploit is a hardcoded private/lab address used by the researcher and is NOT an attacker-controlled infrastructure indicator — it represents the target in the test environment. ↗
·The long-filename DoS vector (vector 4) may persist even on patched versions of pt360 due to an incomplete fix; verify patch completeness against both CVE-2008-1311 and CVE-2008-1312. ↗
