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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

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 2026-10-26.

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.

What to do

AI-suggested

To mitigate this vulnerability effectively, European organizations should: 1) Apply the official patch identified by commit 051465d807a8fcc6a8b0f4bcbb19299672399f48 as soon as it is available and verified. 2) Conduct a thorough code review of the recentthread_forumskip argument handling to ensure proper input validation and output encoding consistent with secure coding standards for web applications. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context, reducing the impact of potential XSS attacks. 4) Enforce strict access controls to limit high privilege accounts that can exploit this vulnerability, including multi-factor authentication and least privilege principles. 5) Educate users about the risks of interacting with suspicious links or content within the platform to minimize successful social engineering attempts. 6) Monitor logs and user activity for unusual behavior that might indicate attempted exploitation. These steps go beyond generic advice by focusing on patching, secure coding practices, layered defenses, and user awareness tailored to the specific nature of this vulnerability.

Description

A vulnerability, which was classified as problematic, was found in dragonexpert Recent Threads on Index. Affected is the function recentthread_list_threads of the file inc/plugins/recentthreads/hooks.php of the component Setting Handler. The manipulation of the argument recentthread_forumskip leads to cross site scripting. It is possible to launch the attack remotely. The patch is identified as 051465d807a8fcc6a8b0f4bcbb19299672399f48. It is recommended to apply a patch to fix this issue. VDB-217182 is the identifier assigned to this vulnerability.

Impact

For European organizations using the dragonexpert platform with the 'Recent Threads on Index' plugin, this vulnerability poses a limited but non-negligible risk. The primary impact is on the integrity of displayed content, potentially allowing attackers to inject misleading or malicious scripts that could trick users into performing unintended actions or reveal session information. However, the requirement for high privileges and user interaction reduces the likelihood of widespread exploitation. Organizations with internal forums or community platforms relying on this plugin may face targeted attacks aiming to disrupt user trust or conduct social engineering. While confidentiality and availability are not directly impacted, the integrity compromise could lead to reputational damage or indirect data exposure if combined with other vulnerabilities. The low CVSS score reflects this limited impact, but organizations should not disregard the risk, especially those in sectors with high regulatory scrutiny or where user trust is paramount.

Summary

CVE-2019-25093 is a cross-site scripting (XSS) vulnerability identified in the 'Recent Threads on Index' plugin of the dragonexpert software. The vulnerability resides in the function recentthread_list_threads within the file inc/plugins/recentthreads/hooks.php, specifically in the handling of the argument recentthread_forumskip. Improper sanitization or validation of this argument allows an attacker to inject malicious scripts that execute in the context of the victim's browser. This vulnerability is classified under CWE-79, which corresponds to improper neutralization of input during web page generation, leading to XSS. The attack can be launched remotely without requiring physical access to the system. However, the CVSS 3.1 base score is 2.4, indicating a low severity, with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:N. This means the attack requires network access, low attack complexity, but high privileges and user interaction, and impacts only the integrity of the system with no confidentiality or availability impact. No known exploits are reported in the wild, and a patch has been identified but not linked in the provided data. The vulnerability primarily allows an attacker to inject scripts that could manipulate or alter displayed content or perform actions on behalf of the user, but given the high privilege requirement and user interaction, exploitation is limited in scope and impact.
