Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Aug 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat has released version 2.11.3 of Advanced Cluster Management for Kubernetes containing fixes for these vulnerabilities. Users should update to version 2.11.3 or later to remediate these issues. Before applying this update, ensure all previously released errata relevant to your system have been applied. Refer to Red Hat's official update documentation for detailed instructions: https://access.redhat.com/articles/11258

Description

Red Hat Advanced Cluster Management for Kubernetes 2.11.3 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. This advisory contains the container images for Red Hat Advanced Cluster Management for Kubernetes. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.6/html/release_notes/ Security fix(es): nodejs/elliptic: EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended (CVE-2024-42459) nodejs/elliptic: ECDSA signature malleability occurs because there is a missing check for whether the leading bit of r and s is zero (CVE-2024-42460) nodejs/elliptic: ECDSA implementation malleability due to BER-enconded signatures being allowed (CVE-2024-42461) CVE-2024-48949 Missing Validation in Elliptic's EDDSA Signature Verification

Impact

The vulnerabilities involve signature malleability and missing validation in cryptographic signature verification, which could potentially allow attackers to manipulate or forge signatures under certain conditions. This could undermine the integrity guarantees of cryptographic operations within the affected product. No known exploits in the wild have been reported. The security impact is rated as Important by Red Hat Product Security.

Summary

This advisory covers multiple vulnerabilities in the nodejs/elliptic cryptographic library used within Red Hat Advanced Cluster Management for Kubernetes. Specifically, CVE-2024-42459 describes EDDSA signature malleability caused by a missing signature length check allowing zero-valued bytes to be removed or appended. CVE-2024-42460 involves ECDSA signature malleability due to missing checks on the leading bit of the r and s values. CVE-2024-42461 relates to ECDSA malleability from allowing BER-encoded signatures. CVE-2024-48949 concerns missing validation in EDDSA signature verification. These issues could affect the integrity of cryptographic signatures. The vulnerabilities are fixed in version 2.11.3 of Red Hat Advanced Cluster Management for Kubernetes.
