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

CriticalCVSS 9.2 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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

Root cause

For convenience in support or manufacturing, an account that is identical on every device is embedded in the software. Credentials learned from one device work on all of them.
