EUVDB-ID: #VU51269
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-18282
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to track devices via UDP packets.
The vulnerability exists due to excessive data output in the flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 and affects net/core/flow_dissector.c and
related code. The auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd
value as a secret, and because jhash (instead of siphash) is used. The
hashrnd value remains the same starting from boot time, and can be
inferred by an attacker. A remote attacker can use the
hashrnd value and track reliably track activity of devices using UDP packets.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
