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 Adversary-in-the-Middle (T1557); ranked at the 27th 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 map to SC-13 (Cryptographic Protection) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
SC-13 requires selection and implementation of specific cryptography types, directly stopping use of broken algorithms.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.DS-01 promotes encryption for data-at-rest but never requires strong algorithms, leaving CWE-327 fully possible; the weakness is also far broader than data-at-rest so one narrow control removes none of its total risk.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating approved algorithms, cipher strength and usage standards directly stops the selection of broken or weak cryptographic primitives that attackers can exploit.
The explicit call-out of cryptography-related legal constraints (import/export, key escrow, digital-signature validity) reduces the likelihood that an organization will adopt broken or non-compliant cryptographic algorithms that violate those rules.
Access to current specialist guidance and early vulnerability alerts enables timely replacement of broken or risky cryptographic algorithms with stronger alternatives.
