CVE-2026-29120 | Insecure, Hardcoded Root Password Stored in Anaconda Configuration File On IDC SFX2100 Satellite Receiver

Exp

The /root/anaconda-ks.cfg installation configuration file in International Datacasting Corporation (IDC) SFX Series(SFX2100) SuperFlex Satellite Receiver insecurely stores the hardcoded root password hash. The password itself is highly insecure and susceptible to offline dictionary attacks using the rockyou.txt wordlist. Because direct root SSH login is disabled, an attacker must first obtain low-privileged access to the system (e.g., via other vulnerabilities) to be able to log in as the root user. The password is hardcoded and so allows for an actor with local access on effected versions to escalate to root

7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/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: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: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.
