Exploitation evidence

Disclosed: evidence found.
CVE published 14 Oct 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 OpenShift Serverless Logic 1.34.0 which includes fixes for these vulnerabilities. Users should apply this update promptly after ensuring all previously released errata relevant to their system are installed. Detailed update instructions are available from Red Hat's official documentation. No additional mitigations are specified beyond applying the official update.

Description

This release includes security, bug fixes, and enhancements. Security Fix(es): * axios: axios: Server-Side Request Forgery (CVE-2024-39338) * express: Improper Input Handling in Express Redirects (CVE-2024-43796) * io.vertx/vertx-grpc-client: Vertx gRPC server does not limit the maximum message size (CVE-2024-8391) * io.vertx/vertx-grpc-server: Vertx gRPC server does not limit the maximum message size (CVE-2024-8391) * send: Code Execution Vulnerability in Send Library (CVE-2024-43799) * serve-static: Improper Sanitization in serve-static (CVE-2024-43800) * webpack: DOM Clobbering vulnerability in AutoPublicPathRuntimeModule (CVE-2024-43788) For more details about the security issues, including the impact, a CVSS score, acknowledgements, and other related information, refer to the CVE pages listed in the References section.

Impact

The vulnerabilities fixed in this update could allow attackers to perform server-side request forgery, improper redirect handling, code execution, and potentially denial of service due to unbounded message sizes in gRPC servers. These issues could compromise the integrity, availability, or security of affected OpenShift Serverless deployments if exploited. The high severity rating indicates significant risk if left unpatched.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.

The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
