Description
This security bulletin contains information about 1 vulnerability.
1) Stack-based buffer overflow (CVE-ID: CVE-2018-7445)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a stack-based buffer overflow when processing NetBIOS session request messages. A remote unauthenticated attacker can send a specially crafted NetBIOS session request message with malformed NetBIOS names, trigger stack-based buffer overflow and cause denial of service conditions or execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to gain full access to the affected router but requires that SMB service is running.
