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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Feb 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

Given the absence of an official patch, European organizations should implement several targeted mitigations: 1) Employ Web Application Firewalls (WAFs) with rules specifically designed to detect and block malicious payloads targeting the 'path' parameter in eyoucms requests. 2) Conduct thorough input validation and output encoding on all user-supplied data, especially URL parameters, to neutralize potential XSS payloads. 3) Educate users and administrators about the risks of clicking on untrusted links and encourage the use of security-aware browsing practices. 4) Monitor web server logs and application behavior for unusual or suspicious URL patterns that may indicate attempted exploitation. 5) If feasible, isolate the eyoucms instance behind reverse proxies or network segmentation to limit exposure. 6) Engage with the eyoucms community or vendor to track the release of official patches or updates and plan timely application once available. 7) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context, mitigating the impact of XSS attacks.

Description

Cross Site Scripting vulnerability in the path parameter in eyoucms v.1.6.5 allows a remote attacker to run arbitrary code via crafted URL.

Impact

For European organizations using eyoucms version 1.6.5, this XSS vulnerability poses a risk primarily to web application security and user trust. Exploitation could lead to theft of user credentials, session tokens, or other sensitive information accessible via the browser, potentially enabling further attacks such as account takeover or privilege escalation. The medium severity indicates a moderate risk, but the requirement for user interaction (clicking a malicious link) somewhat limits automated exploitation. However, organizations in sectors with high web traffic or sensitive user data (e.g., e-commerce, government portals, healthcare) could face reputational damage and regulatory scrutiny under GDPR if user data is compromised. The scope change suggests that the vulnerability could affect multiple components or users beyond the initial entry point, increasing the potential impact. Since no patches are currently available, organizations must rely on mitigation strategies to reduce exposure. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time.

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.
