Summary

CVE-2026-2618 is a medium-severity Use of a Broken or Risky Cryptographic Algorithm (CWE-327) vulnerability in Beetel 777Vr1 Firmware. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 6.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SC-13 (Cryptographic Protection) and SC-8 (Transmission Confidentiality and Integrity).

Deeper analysis

CVE-2026-2618 is a vulnerability affecting the SSH Service component in Beetel 777VR1 devices up to version 01.00.09. The issue stems from the use of a risky cryptographic algorithm in an unknown function, mapped to CWE-310 (Cryptographic Issues) and CWE-327 (Use of a Broken or Risky Cryptographic Algorithm). Published on 2026-02-17, it carries a CVSS v3.1 base score of 3.7 (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

Remote attackers with no required privileges can exploit this vulnerability over the network, though it demands high complexity and is rated as difficult to exploit. Successful attacks enable limited disclosure of sensitive information via the cryptographic weakness, with no impact on integrity or availability.

Advisories from sources like VulDB indicate the exploit has been publicly disclosed, including proof-of-concept steps in a GitHub Gist, and may be utilized by attackers. The vendor was contacted early for coordinated disclosure but provided no response, and no patches or mitigations are referenced.

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The CVE describes a remotely exploitable cryptographic weakness in a public-facing SSH service on a network device, directly enabling remote exploitation for limited information disclosure consistent with initial access via a public-facing application.
