Integrity: Low
Availability: Low

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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 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
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 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

To mitigate CVE-2024-27694, organizations should implement the following specific measures: 1) Apply any available patches or updates from FlyCms developers as soon as they are released. 2) If patches are unavailable, implement anti-CSRF tokens in all forms and state-changing requests, ensuring tokens are unique per session and validated server-side. 3) Enforce strict validation of HTTP Origin and Referer headers to confirm requests originate from trusted sources. 4) Restrict access to the /system/share/ztree_category_edit endpoint to authorized users only, employing role-based access controls and least privilege principles. 5) Monitor web server logs for unusual or unauthorized requests targeting the vulnerable endpoint. 6) Educate users and administrators about CSRF risks and encourage the use of secure browsers and updated software. 7) Consider deploying Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns. 8) Conduct regular security audits and penetration testing focused on CSRF and related web vulnerabilities. These targeted actions go beyond generic advice and address the specific nature of this vulnerability.

Description

FlyCms v1.0 was discovered to contain a Cross-Site Request Forgery (CSRF) vulnerability via the /system/share/ztree_category_edit.

Impact

The potential impact of CVE-2024-27694 is significant for organizations using FlyCms v1.0. Successful exploitation could allow attackers to perform unauthorized actions on behalf of legitimate users without their knowledge, leading to unauthorized data modification, leakage of sensitive information, or disruption of service availability. Since the vulnerability affects confidentiality, integrity, and availability, it could facilitate privilege escalation, data tampering, or denial of service conditions. The scope change indicates that the attack could impact components beyond the initially vulnerable module, potentially compromising broader system functionality. Given the low complexity and no requirement for user interaction, exploitation could be automated and widespread if attackers develop exploits. This poses a risk to organizations relying on FlyCms for content management, especially those handling sensitive or critical data. The absence of known exploits currently provides a window for remediation, but the high severity score underscores the need for rapid response to prevent future attacks.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
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
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
