Exploitation evidence

Disclosed: evidence found.
CVE published 19 Sep 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

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.

AI-suggested

Red Hat has released updated python-webob packages that address this vulnerability. Users of Red Hat OpenStack Platform 17.1 and Red Hat Enterprise Linux 8 should apply the security update as described in Red Hat advisory RHSA-2024:9989. Refer to https://access.redhat.com/articles/11258 for detailed update instructions. No other mitigation actions are indicated by the vendor.

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 4.16.14. See the following advisory for the container images for this release: https://access.redhat.com/errata/RHSA-2024:6824 Security Fix(es): * webob: WebOb's location header normalization during redirect leads to open redirect (CVE-2024-42353) 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 4.16 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/4.16/updating/updating_a_cluster/updating-cluster-cli.html

Impact

The open redirect vulnerability could be exploited to redirect users to malicious websites, potentially facilitating phishing attacks or other social engineering tactics. However, the vulnerability does not directly allow code execution or system compromise. The impact is limited to redirect behavior manipulation in HTTP responses generated by WebOb.

Summary

The vulnerability CVE-2024-42353 in WebOb involves improper normalization of the location header during HTTP redirects, leading to an open redirect flaw. This means that an attacker could manipulate the location header to redirect users to arbitrary external URLs. The affected software includes python-webob packages in Red Hat OpenStack Platform 17.1 for RHEL 8 and Red Hat Enterprise Linux 8. Red Hat has released updated packages (python-webob-1.8.7-2.1.el8ost) to fix this issue as detailed in advisory RHSA-2024:9989. No CVSS score is provided, but the vendor rates the impact as moderate.

CWE-601URL Redirection to Untrusted Site ('Open Redirect') (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
