Summary

CVE-2023-22463 is a critical-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Fit2Cloud Kubepi. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked in the top 0.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

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

KubePi, an open-source Kubernetes management panel, is affected by CVE-2023-22463 in all versions through 1.6.2. The JWT authentication logic in session.go relies on a hard-coded JwtSigKey constant, so every online deployment uses the identical signing secret. This constitutes use of hard-coded credentials (CWE-798) and carries a CVSS 3.1 score of 9.8.

An unauthenticated network attacker can therefore craft arbitrary JWT tokens that are accepted by any reachable KubePi instance. Successful forgery grants full administrative control over the panel, which in turn permits takeover of the target organization’s Kubernetes cluster.

The issue is resolved in release 1.6.3 by reading the signing key from app.yml and falling back to a randomly generated value when the field is empty. The project’s GitHub Security Advisory and release notes state that no other mitigations exist and explicitly recommend upgrading. The associated EPSS score stands at 0.9152.

Vulnerability Data

KubePi is a k8s panel. The jwt authentication function of KubePi through version 1.6.2 uses hard-coded Jwtsigkeys, resulting in the same Jwtsigkeys for all online projects. This means that an attacker can forge any jwt token to take over the…

administrator account of any online project. Furthermore, they may use the administrator to take over the k8s cluster of the target enterprise. `session.go`, the use of hard-coded JwtSigKey, allows an attacker to use this value to forge jwt tokens arbitrarily. The JwtSigKey is confidential and should not be hard-coded in the code. The vulnerability has been fixed in 1.6.3. In the patch, JWT key is specified in app.yml. If the user leaves it blank, a random key will be used. There are no workarounds aside from upgrading.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-798

Enables users to notice when hard-coded credentials have been exploited for unauthorized access.

addresses: CWE-798

Security training explicitly warns against hard-coded credentials, lowering their use in systems.

addresses: CWE-798

Policy and procedures prohibit hard-coded credentials in favor of managed authentication.

addresses: CWE-798

External identity providers eliminate the need for hard-coded credentials in applications.

addresses: CWE-798

Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.

addresses: CWE-798

Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.

addresses: CWE-798

Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.

addresses: CWE-798

Planned investment enables secure credential storage and management systems instead of hard-coded credentials.

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.

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.

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.
