Exploitation evidence

Disclosed: evidence found.
CVE published 5 Dec 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 13 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

What to do

Upgrade Red Hat to 3.7.17-r1 or 2.12.1.

AI-suggested

Apply the Red Hat Advanced Cluster Management for Kubernetes 2.12.1 update, which contains fixes for these ReDoS vulnerabilities. Before updating, ensure all previously released errata relevant to your system are applied. No additional mitigation steps are indicated by the vendor advisory.

Description

Red Hat Advanced Cluster Management for Kubernetes 2.12.1 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://access.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)

Impact

Successful exploitation of these vulnerabilities could lead to denial of service conditions due to resource exhaustion from inefficient regular expression processing. This could impact availability of the Red Hat Advanced Cluster Management for Kubernetes service. No information is provided about privilege escalation or data compromise. The impact is rated moderate by Red Hat Product Security.

Summary

This advisory for Red Hat Advanced Cluster Management for Kubernetes 2.12.1 addresses two ReDoS vulnerabilities: CVE-2024-45296 caused by backtracking regular expressions, and CVE-2024-45813 involving multiparametric routes. These vulnerabilities could allow an attacker to cause denial of service by exploiting inefficient regular expression processing. The update includes bug fixes and container image updates to remediate these issues. The affected versions are >=2.12.0 and <2.12.1. No CVSS scores are provided, but the vendor rates the impact as moderate. There are no known exploits in the wild at the time of the advisory. The vendor advisory is the authoritative source for remediation.

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.
