Summary

CVE-2024-53356 is a critical-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Easyvirt Co2Scope. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 48th 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 IA-5 (Authenticator Management) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-53356 is a weak JWT secret vulnerability affecting EasyVirt DCScope versions up to and including 8.6.0 and CO2Scope versions up to and including 1.3.0. The issue stems from a hardcoded HMAC secret, specifically "somerandomaccesstoken", used for generating JSON Web Tokens (JWTs). This predictable secret enables attackers to forge valid tokens, leading to privilege escalation within the application.

Remote attackers can exploit this vulnerability without authentication, as indicated by its CVSS v3.1 score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). By crafting JWTs with the known secret, unauthenticated adversaries gain unauthorized access to sensitive information and perform privileged actions, potentially compromising the full confidentiality, integrity, and availability of the affected systems.

Advisories detailing the vulnerability, including potential mitigation steps, are available in the referenced GitHub repository at https://github.com/Elymaro/CVE/blob/main/EasyVirt/CVE-2024-53356.md. The issue is classified under CWE-798 (Use of Hard-coded Credentials).

Vulnerability Data

Weak JWT Secret vulnerabilitiy in EasyVirt DCScope <= 8.6.0 and CO2Scope <= 1.3.0 allows remote attackers to generate JWT for privilege escalation. The HMAC secret used for generating tokens is hardcoded as "somerandomaccesstoken". A weak HMAC secret poses a risk…

because attackers can use the predictable secret to create valid JSON Web Tokens (JWTs), allowing them access to important information and actions within the application.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Authenticator management requires secure distribution and handling of credentials, structurally discouraging hard-coded values.

Cryptographic key management mandates proper establishment and handling instead of embedding keys in code.

Mitigating Controls (NIST CSF 2.0) AI

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.AA-01 partial match
prevents

PR.AA-01's credential/key-management processes can reduce the incentive to embed secrets but do not address or detect hard-coded values in source code, so the weakness remains fully possible.

PR.AA-02 none match
prevents

PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.

PR.DS-01 none match
prevents

PR.DS-01 addresses encryption and integrity of stored data but never touches credential or key management practices, so it neither prevents hard-coded credentials nor removes any of their risk.

prevents

Education on secure configuration practices discourages technical staff from embedding or relying on hard-coded credentials in systems and applications.

mitigates

Secure key-generation, distribution and storage procedures reduce the likelihood that hard-coded or default cryptographic keys will be introduced or left unprotected.

prevents

Explicit prohibition of hard-coded passwords and unauthenticated external services stops credentials from being embedded directly in source code.

prevents

Contractual requirements for secure coding practices and evidence of testing make it less likely that hard-coded credentials will be introduced or remain undetected in delivered code.

none

Requiring independent oversight and timely disabling of non-human identities makes it harder for hard-coded or long-lived credentials to remain exploitable.

none

Mandating immediate replacement of vendor-supplied default credentials eliminates the use of hard-coded or factory passwords that attackers can trivially obtain from documentation or firmware.
