Exploitation evidence

Disclosed: evidence found.
CVE published 5 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 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 updated packages and container images in OpenShift Container Platform 4.12.70 that fix these vulnerabilities. Users should upgrade to these updated versions as soon as they are available in their release channel. The vendor provides detailed upgrade instructions via the OpenShift CLI or web console. Patch status is confirmed with an official fix available. No additional mitigations are specified beyond applying the update.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.12.70. See the following advisory for the container images for this release: https://access.redhat.com/errata/RHBA-2024:10533 Security Fix(es): * waitress: python-waitress: request processing race condition in HTTP pipelining with invalid first request (CVE-2024-49768) * waitress: Waitress has a denial of service leading to high CPU usage/resource exhaustion (CVE-2024-49769) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. All OpenShift Container Platform 4.12 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.openshift.com/container-platform/4.12/updating/updating-cluster-cli.html

Impact

Exploitation of these vulnerabilities can lead to denial of service conditions in OpenShift Container Platform environments by causing high CPU usage and resource exhaustion. The race condition in HTTP pipelining may also affect request processing reliability. These issues impact the stability and availability of affected OpenShift clusters.

Summary

This advisory addresses two security vulnerabilities in the python-waitress server used by Red Hat OpenShift Container Platform 4.12. The first vulnerability (CVE-2024-49768) is a race condition during HTTP request processing involving pipelining with an invalid first request. The second vulnerability (CVE-2024-49769) allows an attacker to cause a denial of service by triggering high CPU usage and resource exhaustion. Red Hat has released updated RPM packages and container images in OpenShift Container Platform 4.12.70 to remediate these issues. Users are advised to upgrade their clusters using the OpenShift CLI or web console following Red Hat's documented procedures.

CWE-444Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
Implementation
Use a web server that employs a strict HTTP parsing procedure, such as Apache.
Implementation
Use only SSL communication.
Implementation
Terminate the client session after each request.

CWE-772Missing Release of Resource after Effective Lifetime (opens in a new tab)
Base weaknessLikelihood of exploit: High
The product does not release a resource after its effective lifetime has ended, i.e., after the resource is no longer needed.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free resources in a function. If you allocate resources that you intend to free upon completion of the function, you must be sure to free the resources at all exit points for that function including…
Operation · Architecture and Design · Resource Limitation
Use resource-limiting settings provided by the operating system or environment. For example, when managing system resources in POSIX, setrlimit() can be used to set limits for certain types of resources, and getrlimit() can determine how many resources are available.
