Exploitation evidence

Disclosed: evidence found.
CVE published 21 Nov 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

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 31 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.
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

AI-suggested

Red Hat has released updated python-webob packages (version 1.8.7-2.1.el9ost) for Red Hat OpenStack Platform 17.1 and Red Hat Enterprise Linux 9 that address this open redirect vulnerability. Users should apply these updates promptly by following the instructions in the Red Hat advisory (https://access.redhat.com/articles/11258). No alternative mitigations or workarounds are specified, so patching is the recommended remediation.

Description

A security vulnerability (CVE-2024-42353) in WebOb, a Python library used for WSGI request and response handling, involves improper normalization of the Location header during HTTP redirects. This flaw can lead to an open redirect vulnerability. The issue affects Red Hat OpenStack Platform 17.1 and Red Hat Enterprise Linux 9 packages of python-webob. Red Hat has issued a security advisory with an update to address this vulnerability.

Impact

The vulnerability allows an attacker to craft a malicious redirect via the Location header, potentially redirecting users to unintended external sites. This can be leveraged in phishing or social engineering attacks to deceive users. The overall impact is rated moderate by Red Hat, indicating a security risk that could lead to user redirection abuse but not direct code execution or system compromise.

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.
