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 23 Jan 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

European organizations should implement immediate compensating controls to reduce risk. These include: 1) Educating administrators and users about the risk of clicking untrusted links, especially those purporting to be related to the admin login page. 2) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the password parameter in the /admin/login endpoint. 3) Enforcing Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the admin interface. 4) Employing input validation and output encoding at the application layer if possible, or applying temporary patches or filters to sanitize the password parameter. 5) Monitoring logs for unusual access patterns or repeated attempts to exploit the login page. 6) Planning and prioritizing an upgrade or patch deployment once the vendor releases an official fix. 7) Using multi-factor authentication (MFA) for admin accounts to mitigate the impact of session hijacking or credential theft. These measures go beyond generic advice by focusing on immediate actionable steps tailored to the vulnerability's characteristics and the affected endpoint.

Description

Cross Site Scripting (XSS) vulnerability in /admin/login password parameter in JFinalcms 5.0.0 allows attackers to run arbitrary code via crafted URL.

Impact

For European organizations using JFinalcms 5.0.0, especially those managing sensitive or critical content via the admin interface, this XSS vulnerability poses a significant risk. Successful exploitation could lead to unauthorized access to administrative sessions, enabling attackers to manipulate content, steal sensitive data, or escalate privileges. Given the scope change indicated in the CVSS vector, the vulnerability could allow attackers to affect resources beyond the initially targeted component, potentially compromising broader system integrity. This is particularly concerning for organizations in sectors such as government, finance, healthcare, and media, where content integrity and confidentiality are paramount. Additionally, since the vulnerability requires user interaction, targeted phishing or social engineering campaigns could be used to trick administrators into clicking malicious links, increasing the risk of compromise. The absence of patches means organizations remain exposed until mitigations are applied. The impact on confidentiality and integrity, combined with the potential for session hijacking or credential theft, could lead to data breaches, reputational damage, and regulatory non-compliance under GDPR and other European data protection laws.

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.
