Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

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 2026-10-25.

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

European organizations should immediately implement input validation and output encoding controls on the 'nome' parameter within their deployment of i-Educar, if possible, to neutralize malicious scripts. Deploying a Web Application Firewall (WAF) with custom rules to detect and block typical XSS payloads targeting the vulnerable endpoint can provide a temporary protective layer. Organizations should restrict access to the intranet interface hosting the vulnerable script to trusted networks and authenticated users only, reducing exposure. Regularly monitoring web server logs for suspicious requests targeting /intranet/funcionario_vinculo_lst.php can help detect exploitation attempts early. User awareness training to recognize phishing or suspicious links can reduce the risk of successful user interaction exploitation. Finally, organizations should engage with Portabilis or community forums for updates or unofficial patches and plan for an upgrade once a fix is available.

Description

A vulnerability classified as problematic has been found in Portabilis i-Educar 2.9. This affects an unknown part of the file /intranet/funcionario_vinculo_lst.php. The manipulation of the argument nome leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Portabilis i-Educar 2.9, this vulnerability poses a moderate risk. Educational institutions often manage sensitive personal data of students and staff, so exploitation could lead to unauthorized access to confidential information or session hijacking. This could result in data breaches, reputational damage, and regulatory non-compliance under GDPR. The remote exploitability without authentication increases the attack surface, especially if the affected systems are accessible from the internet or internal networks with many users. However, the requirement for user interaction somewhat limits automated exploitation. The lack of vendor response and patch availability means organizations must rely on other mitigations, increasing operational risk. If exploited, attackers could manipulate user sessions or inject malicious content, potentially disrupting educational services or compromising user trust.

Summary

CVE-2025-8367 is a cross-site scripting (XSS) vulnerability identified in version 2.9 of Portabilis i-Educar, an educational management system. The vulnerability exists in the /intranet/funcionario_vinculo_lst.php file, specifically through improper handling of the 'nome' parameter. This flaw allows an attacker to inject malicious scripts that execute in the context of a victim's browser when they access a crafted URL or input. The vulnerability is remotely exploitable without requiring authentication, and user interaction is needed to trigger the malicious payload, such as clicking a malicious link or visiting a compromised page. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, and user interaction needed. The impact primarily affects confidentiality and integrity, with limited impact on availability. The vendor has been contacted but has not responded or issued a patch, and no known exploits are currently in the wild. Given the public disclosure, the risk of exploitation may increase over time. XSS vulnerabilities can be leveraged for session hijacking, credential theft, or delivering further malware, especially in web applications handling sensitive user data like educational records.
