CVE-2018-10057 : Vulnerability Insights and Analysis

An authenticated remote attacker can exploit the absence of basedir restrictions (absolute directory traversal) in the remote management interface of cgminer 4.10.0 and bfgminer 5.5.0. This exploit enables the attacker to write the miner configuration file to any designated location on the server.

Understanding CVE-2018-10057

This CVE entry describes a vulnerability in the remote management interface of cgminer and bfgminer that allows an authenticated remote attacker to write the miner configuration file to arbitrary locations on the server.

What is CVE-2018-10057?

The vulnerability in cgminer 4.10.0 and bfgminer 5.5.0 enables an authenticated remote attacker to perform absolute directory traversal, bypassing basedir restrictions. This allows the attacker to write the miner configuration file to any location on the server.

The Impact of CVE-2018-10057

The exploitation of this vulnerability can lead to unauthorized modification of miner configurations, potentially disrupting mining operations and compromising the integrity of the server.
