EUVDB-ID: #VU13403
Risk: High
CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-5702
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary RPC commands on the target system.
The vulnerability exists in the Remote Procedure Call (RPC) session-id mechanism in Transmission due to bthe affected software uses the X-Transmission-Session-Id header for access control. A remote unauthenticated attacker can conduct a DNS rebinding attack, register a domain name and make it resolve to localhost, then delegate the domain name to an attacker-controlled DNS server that is configured to respond with a short time-to-live (TTL) record, trick the victim into following a link that submits malicious input, execute arbitrary RPC commands and arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
Install update from vendor's website.
