GHSA-m2c7-42rf-c62f — high GitHub Advisory (CVE-2021-44255) in pip/motioneye

Description

motionEye <= 0.42.1 and motioneEyeOS <= 20200606 allow a remote attacker to upload a configuration backup file containing a malicious python pickle file. This is possible when an installation is accessible over the Internet and uses no or poor authentication credentials.

The GitHub repositories for motionEye and motionEyeOS are no longer being actively maintained as of January 2022, so release of a patched version is unlikely. Keeping a motionEye or motionEyeOS installation off of the Internet and/or using strong credentials provide protection against this issue.

CVSS Scores

Base score	Version	Severity	Vector
7.2	3.1	—	`CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H` Click to expand Attack vector (AV:N) Could be attacked over the internet or any normal routed network—not just someone sitting at the machine. 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:H) They need powerful rights—admin, root, or similar—before this pays off. 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.
