CVE-2024-24324
Exposed Creds in Totolink A8000Ru Firmware 7.1cu.643_b20200521
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2024-24324 is a critical-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Totolink A8000Ru Firmware. 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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
TOTOLINK A8000RU firmware version 7.1cu.643_B20200521 contains a hardcoded root password stored in /etc/shadow. The issue is tracked as CVE-2024-24324 with a CVSS 3.1 score of 9.8 and is classified under CWE-798 for use of hard-coded credentials.
An unauthenticated attacker with network access can authenticate directly as root using the embedded credential. Successful exploitation grants full administrative control over the device, allowing arbitrary command execution and complete compromise of confidentiality, integrity, and availability.
Public disclosure references consist of GitHub repositories that document the hardcoded credential. The EPSS score rose from a low baseline to a peak of 0.0994 on 2025-01-22 before receding to the current value of 0.0010, indicating a period of increased exploitation interest after the initial publication.

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'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 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 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.

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.
Education on secure configuration practices discourages technical staff from embedding or relying on hard-coded credentials in systems and applications.
Secure key-generation, distribution and storage procedures reduce the likelihood that hard-coded or default cryptographic keys will be introduced or left unprotected.
Explicit prohibition of hard-coded passwords and unauthenticated external services stops credentials from being embedded directly in source code.
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.
Requiring independent oversight and timely disabling of non-human identities makes it harder for hard-coded or long-lived credentials to remain exploitable.
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.
