CVE-2019-1667 | Cisco HyperFlex Arbitrary Statistics Write Vulnerability

A vulnerability in the Graphite interface of Cisco HyperFlex software could allow an authenticated, local attacker to write arbitrary data to the Graphite interface. The vulnerability is due to insufficient authorization controls. An attacker could exploit this vulnerability by connecting to the Graphite service and sending arbitrary data. A successful exploit could allow the attacker to write arbitrary data to Graphite, which could result in invalid statistics being presented in the interface. Versions prior to 3.5(2a) are affected.

Base score Version Severity Vector Exploitability Impact Score source
3.3 3.1 LOW
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
