Exploitation evidence

Disclosed: evidence found.
CVE published 18 Dec 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 2026-10-25.

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 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.

What to do

Upgrade Red Hat to 2.12.0.

AI-suggested

Red Hat has released version 2.11.4 of Advanced Cluster Management for Kubernetes which includes fixes for these vulnerabilities. Users should apply this update after ensuring all prior errata are applied. The vendor advisory does not indicate that no action is required or that the issues are already mitigated, so updating to the fixed version is recommended to address these security concerns.

Description

Red Hat Advanced Cluster Management for Kubernetes 2.11.4 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, which fix several bugs. See the following Release Notes documentation, which gets updated for this release, for additional details about this release: https://docs.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.12/html/release_notes/ Security fix(es): Backtracking regular expressions cause ReDoS (CVE-2024-45296) ReDoS vulnerability in multiparametric routes (CVE-2024-45813) XSS vulnerability via prototype pollution (CVE-2024-4580)1

Impact

The vulnerabilities fixed in this release could allow denial of service through regular expression backtracking and cross-site scripting attacks via prototype pollution. These issues may affect the stability and security of the cluster management environment. The severity is rated moderate, indicating a significant but not critical risk. No known exploits in the wild have been reported at this time.

Summary

This advisory covers Red Hat Advanced Cluster Management for Kubernetes 2.11.4 container images which fix multiple security issues: CVE-2024-45296 involves a ReDoS vulnerability caused by backtracking regular expressions; CVE-2024-45813 is a ReDoS vulnerability in multiparametric routes; and CVE-2024-45801 is an XSS vulnerability via prototype pollution. The update also fixes various bugs affecting policy status updates, operator installation, certificate policy expiration, image pull secrets retrieval, and alertmanager behavior. The advisory references Red Hat's official errata RHSA-2024:11381 and release notes for detailed information.

CWE-1333Inefficient Regular Expression Complexity (opens in a new tab)
Base weaknessLikelihood of exploit: High
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
Architecture and Design
Use regular expressions that do not support backtracking, e.g. by removing nested quantifiers.
System Configuration
Set backtracking limits in the configuration of the regular expression implementation, such as PHP's pcre.backtrack_limit. Also consider limits on execution time for the process.
Implementation
Do not use regular expressions with untrusted input. If regular expressions must be used, avoid using backtracking in the expression.
