Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 May 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

Restrict access to the add_post.php component by enforcing strict authentication and authorization controls, ensuring only trusted users can interact with this functionality.
Implement input validation and sanitization on all user-supplied data to prevent code injection, particularly focusing on parameters handled by add_post.php.
Monitor CMS logs for unusual activity or unexpected code execution attempts related to the add_post.php endpoint.
Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting code injection vectors.
Conduct regular security audits and code reviews of the CMS, especially custom or third-party components, to identify and remediate unsafe coding practices.
Isolate the CMS environment and limit its network privileges to reduce potential lateral movement if exploited.
Stay alert for official patches or updates from the flusity-CMS maintainers and apply them promptly once available.
Educate administrators and developers about the risks of CWE-94 vulnerabilities and secure coding standards to prevent similar issues.

Description

An issue in flusity-CMS v.2.33 allows a remote attacker to execute arbitrary code via the add_post.php component.

Impact

The primary impact of CVE-2024-33442 is on the integrity of systems running flusity-CMS version 2.33. Successful exploitation could allow attackers to execute arbitrary code, potentially enabling unauthorized content manipulation, deployment of malicious scripts, or further lateral movement within the network. While confidentiality and availability are not directly impacted, the integrity compromise could lead to reputational damage, data tampering, and indirect availability issues if malicious code disrupts normal operations. Organizations relying on flusity-CMS for content management, especially those with sensitive or high-traffic websites, could face defacement, misinformation dissemination, or use as a pivot point for broader attacks. The requirement for some level of privileges reduces the risk somewhat but does not eliminate it, especially in environments with weak access controls or credential management.

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
Architecture and Design · Refactoring
Refactor your program so that you do not have to dynamically generate code.
Architecture and Design
Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
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.
