Summary

CVE-2026-35682 is a high-severity Command Injection (CWE-77) vulnerability in Anviz Cx2 Lite Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked in the top 24.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-35682 is an authenticated command injection vulnerability in Anviz CX2 Lite, where a filename parameter allows attackers to execute arbitrary commands, such as starting telnetd, resulting in root-level access. This flaw is classified under CWE-77 (Command Injection) and carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility, low attack complexity, and significant impacts on confidentiality, integrity, and availability.

An authenticated attacker with low privileges (PR:L) can exploit this vulnerability over the network without user interaction. By injecting malicious commands into the filename parameter, they achieve arbitrary command execution with root privileges, enabling full system compromise, including potential persistence, data exfiltration, or further lateral movement.

CISA's ICS Advisory ICSA-26-106-03 details the vulnerability and mitigation recommendations, available at https://www.cisa.gov/news-events/ics-advisories/icsa-26-106-03 and in CSAF JSON format at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-106-03.json.
