CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Multiple DrayTek VigorSwitch models contain a directory traversal vulnerability in the getSyslogFile function. The vulnerability is caused by insufficient validation of the option field. A remote attacker can trigger this vulnerability via crafted input containing path traversal sequences to access arbitrary files on the device. Exploitation requires valid administrative credentials for the device's web management interface.
