Exploitation evidence

Disclosed: evidence found.
CVE published 13 Mar 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 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.

What to do

Upgrade Red Hat to 4.3.5.

AI-suggested

Users of RHACS 4.3 versions prior to 4.3.5 are advised to upgrade to version 4.3.5, which contains official fixes for the SQL injection vulnerabilities and resolves the Central component crash loop issue. No additional mitigation steps are indicated or required beyond applying this update.

Description

This release of RHACS 4.3.5 provides the following bug fix: * Fixed an issue where an upgrade to RHACS 4.3 from a previous version caused the Central component to enter a crash loop. It provides the following security fixes: * pgx: SQL Injection via Protocol Message Size Overflow (CVE-2024-27304) * pgx: SQL Injection via Line Comment Creation (CVE-2024-27289) 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.

Impact

Successful exploitation of these vulnerabilities could allow an attacker to perform SQL injection attacks against the RHACS Central database, potentially leading to unauthorized data access or manipulation within the affected component. The advisory does not provide detailed exploitation scenarios or confirm active exploitation in the wild. The overall security impact is rated as moderate.

Summary

This advisory covers two SQL injection vulnerabilities in the pgx component of Red Hat Advanced Cluster Security for Kubernetes (RHACS) 4.3 prior to 4.3.5. CVE-2024-27304 involves SQL injection via protocol message size overflow, and CVE-2024-27289 involves SQL injection via line comment creation. Both vulnerabilities could allow an attacker to manipulate SQL queries. The update to RHACS 4.3.5 includes fixes for these vulnerabilities and resolves an upgrade-related crash loop in the Central component. No CVSS scores are provided in the advisory, but Red Hat rates the security impact as moderate.

CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #2OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
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.
Architecture and Design · Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Architecture and Design · Operation · Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment.
