Description:
Liu Qixu has discovered a vulnerability in 3CTftpSvc, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error during the processing of TFTP Read/Write request packet types. This can be exploited to cause a stack-based buffer overflow by sending a specially crafted packet with an overly long mode field (more than 460 bytes).
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 2.0.1. Other versions may also be vulnerable.
