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

Disclosed: evidence found.
CVE published 5 Aug 2025
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

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 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.

2) Web Application Firewall (WAF): Deploy or update WAF rules to detect and block XSS attack patterns targeting the vulnerable parameter. 3) Content Security Policy (CSP): Implement CSP headers to restrict the execution of unauthorized scripts within the application context. 4) User awareness: Educate users to avoid clicking suspicious links or interacting with untrusted content related to the application. 5) Monitoring and logging: Enhance monitoring to detect anomalous activities indicative of XSS exploitation attempts. 6) Segmentation and least privilege: Limit access to the intranet application to trusted networks and users to reduce exposure. 7) Vendor engagement: Continue efforts to engage the vendor for an official patch and consider alternative software if remediation is delayed. These measures collectively reduce the risk until a formal fix is released.

Description

A vulnerability was found in Portabilis i-Educar 2.10. It has been classified as problematic. This affects an unknown part of the file /intranet/public_municipio_cad.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 2.10, particularly educational institutions and municipal education departments, this vulnerability poses a risk to the confidentiality and integrity of user data and sessions. Successful exploitation could allow attackers to steal authentication tokens, perform actions on behalf of users, or deliver malware through the application interface. This could disrupt educational operations, compromise sensitive student or staff information, and damage institutional reputation. Given the software's role in managing educational data, the impact extends to compliance with data protection regulations such as GDPR. Although the vulnerability does not directly impact system availability, the indirect consequences of data breaches or unauthorized access could be significant. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.

Summary

CVE-2025-8540 is a cross-site scripting (XSS) vulnerability identified in version 2.10 of Portabilis i-Educar, an educational management software platform. The vulnerability arises from improper sanitization of the 'nome' parameter in the /intranet/public_municipio_cad.php file, allowing an attacker to inject malicious scripts. This flaw can be exploited remotely without authentication, requiring only user interaction to trigger the malicious payload. The vulnerability is classified as medium severity with a CVSS 4.8 score, reflecting its moderate impact and ease of exploitation. The vendor has been notified but has not responded or issued a patch. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability primarily affects the confidentiality and integrity of user sessions and data by enabling script injection, which could lead to session hijacking, defacement, or redirection to malicious sites. Availability impact is minimal. The vulnerability does not require elevated privileges but does require user interaction, such as clicking a crafted link or visiting a malicious page that exploits the vulnerable parameter.
