Attack Vector: Local
Attack Complexity: Low
Privileges Required: Low
User Interaction: Required
Scope: Changed
Confidentiality: Low
Integrity: Low
Availability: None

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: 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 18 Apr 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.

What to do

AI-suggested

Monitor vendor communications closely for official patches or updates addressing CVE-2024-30924 and apply them promptly once available.
Implement strict input validation and output encoding on all user-supplied data processed by checkin.php to prevent script injection.
Restrict access to the checkin.php component to trusted users and networks, employing network segmentation and access controls.
Educate users about the risks of clicking on untrusted links or submitting unverified input to reduce the likelihood of successful user interaction exploitation.
Deploy Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting DerbyNet.
Conduct regular security assessments and code reviews focusing on input handling in DerbyNet components.
Implement Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers.
Monitor logs for unusual activity related to the checkin.php endpoint to detect potential exploitation attempts early.

Description

Cross Site Scripting vulnerability in DerbyNet v9.0 and below allows attackers to execute arbitrary code via the checkin.php component.

Impact

For European organizations, this vulnerability poses a risk primarily to confidentiality and integrity of web sessions and data handled by DerbyNet. Attackers exploiting this XSS flaw could hijack user sessions, steal sensitive information, or manipulate user interactions, potentially leading to unauthorized access or data leakage. Organizations relying on DerbyNet for internal communications, project management, or customer-facing portals could see reputational damage and operational disruptions if exploited. The requirement for local access and user interaction limits the scale of automated widespread attacks but does not eliminate targeted spear-phishing or insider threat scenarios. Given the medium severity and the lack of known exploits, the immediate risk is moderate; however, organizations should proactively mitigate to prevent escalation. The impact is more significant in sectors where DerbyNet is integrated with critical business processes or sensitive data, such as finance, healthcare, or government services within Europe.

Compound weakness
The product uses a denylist-based protection mechanism to defend against XSS attacks, but the denylist is incomplete, allowing XSS variants to succeed.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
