CVE-2018-12326

Exp

Buffer overflow in redis-cli of Redis before 4.0.10 and 5.x before 5.0 RC3 allows an attacker to achieve code execution and escalate to higher privileges via a crafted command line. NOTE: It is unclear whether there are any common situations in which redis-cli is used with, for example, a -h (aka hostname) argument from an untrusted source.

Base score Version Severity Vector Exploitability Impact Score source
8.4 3.0 HIGH
CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H 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:N)
No account or special rights needed—anonymous or random user is enough.
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:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
