What is CVE-2013-5757?
The Yealink VoIP Phone SIP-T38G is susceptible to an absolute path traversal vulnerability, which permits remote authenticated users to read arbitrary files on the device. This is achieved through the 'dumpConfigFile' function within the 'cgiServer.exx' script, allowing an attacker to manipulate the command parameter to access sensitive data using a full pathname.
Exploit Proof of Concept (PoC)
PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
