Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed

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 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-sqlparse packages for Red Hat OpenStack Platform 17.1 as detailed in advisory RHSA-2024:9986. Users should apply these official updates to remediate the vulnerability. For update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are specified or required beyond applying the vendor-provided patch.

Description

sqlparse is a tool for parsing SQL strings Security Fix(es): * parsing heavily nested list leads to denial of service (CVE-2024-4340) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.

Impact

The vulnerability can cause denial of service by triggering resource exhaustion or failure when parsing deeply nested SQL lists. This could disrupt services relying on python-sqlparse within affected Red Hat OpenStack Platform 17.1 environments. There are no reports of active exploitation in the wild. The impact is rated moderate by Red Hat.

Summary

The vulnerability CVE-2024-4340 affects the python-sqlparse tool used in Red Hat OpenStack Platform 17.1. It involves a denial of service caused by parsing heavily nested lists. Red Hat Product Security has classified the severity as moderate and released updated packages as part of RHSA-2024:9986 to fix the issue. The vulnerability is tracked under CWE-674 (Improper Control of a Resource Through a Logic Error). No CVSS score is provided in the advisory, but the impact is limited to denial of service conditions.

CWE-674Uncontrolled Recursion (opens in a new tab)
Class weakness
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
Implementation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Implementation
Increase the stack size.
Attack patterns
