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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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

Exploitation evidence

Detectable: no evidence on record.

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

Organizations should implement immediate mitigations including input validation and output encoding on the 'nome' parameter within the /module/RegraAvaliacao/edit functionality. Web Application Firewalls (WAFs) can be configured to detect and block typical XSS payloads targeting this endpoint. Administrators should restrict user privileges to minimize the impact of potential exploitation, ensuring that only trusted users can access the vulnerable module. Monitoring and logging of unusual activities related to this endpoint should be enhanced to detect exploitation attempts early. User education on phishing and suspicious links can reduce the risk of successful exploitation. Finally, organizations should maintain regular backups and incident response plans tailored to web application attacks.

Description

A vulnerability classified as problematic was found in Portabilis i-Educar 2.10. Affected by this vulnerability is an unknown functionality of the file /module/RegraAvaliacao/edit. The manipulation of the argument nome leads to cross site scripting. The attack can be launched 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, particularly educational institutions using Portabilis i-Educar 2.10, this vulnerability poses a risk of session hijacking, unauthorized actions, and potential data exposure through client-side script execution. While the direct impact on system integrity and availability is limited, the exploitation of XSS can lead to broader attacks such as phishing or credential theft, undermining trust in the educational platform. Given the sensitive nature of educational data and the importance of maintaining secure access for students and staff, exploitation could disrupt educational processes and compromise personal information. The lack of vendor response and absence of patches increases the risk exposure. Additionally, the public disclosure of the exploit code may encourage opportunistic attackers targeting European educational entities, especially those with limited cybersecurity resources.

Summary

CVE-2025-8544 is a cross-site scripting (XSS) vulnerability identified in version 2.10 of Portabilis i-Educar, an educational management system. The vulnerability arises from improper sanitization of the 'nome' parameter in the /module/RegraAvaliacao/edit endpoint. An attacker can remotely manipulate this parameter to inject malicious scripts, which are then executed in the context of the victim's browser. This type of vulnerability can be exploited to steal session cookies, perform actions on behalf of the user, or deliver malicious payloads. The vulnerability has been publicly disclosed, and while no known exploits are currently observed in the wild, the availability of the exploit code increases the risk of exploitation. The vendor was notified but has not responded, and no patches are currently available. The CVSS 4.0 base score is 4.8 (medium severity), reflecting that the attack vector is network-based with low attack complexity, no privileges required, but user interaction is necessary. The impact on confidentiality is none, with low impact on integrity due to limited scope, and no impact on availability. The vulnerability affects a specific module related to evaluation rules, which is likely used by educational institutions to manage grading criteria.
