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

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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.

AI-suggested

Given the absence of an official patch, European organizations should implement immediate compensating controls. These include: 1) Input validation and output encoding on the affected parameter 'nm_raca' at the web application firewall (WAF) or reverse proxy level to block or sanitize malicious payloads. 2) Deploy Content Security Policy (CSP) headers to restrict script execution sources and reduce the impact of injected scripts. 3) Educate users on phishing and social engineering risks to minimize the likelihood of triggering malicious scripts. 4) Restrict access to the intranet module to trusted networks or VPNs to limit exposure. 5) Monitor web server and application logs for suspicious parameter usage patterns indicative of exploitation attempts. 6) Consider temporary disabling or restricting the vulnerable functionality if feasible. 7) Plan for an upgrade or migration to a patched version once available or evaluate alternative platforms. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable parameter and the operational context of i-Educar.

Description

A vulnerability classified as problematic has been found in Portabilis i-Educar 2.10. Affected is an unknown function of the file /intranet/educar_raca_cad.php. The manipulation of the argument nm_raca leads to cross site scripting. It is possible to launch 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, especially educational institutions using Portabilis i-Educar 2.10, this vulnerability poses a risk of unauthorized access to sensitive educational data and user credentials. Exploitation could lead to session hijacking, enabling attackers to impersonate legitimate users and potentially manipulate student records, grades, or personal information. This could result in data breaches violating GDPR requirements, leading to regulatory penalties and reputational damage. Additionally, compromised accounts could be leveraged for further lateral movement within institutional networks. The lack of vendor response and patch availability increases the urgency for European entities to implement mitigations. The impact is particularly significant for institutions with large user bases or those that rely heavily on i-Educar for critical administrative functions.

Summary

CVE-2025-8543 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 'nm_raca' parameter in the /intranet/educar_raca_cad.php file. An attacker can manipulate this parameter to inject malicious scripts that execute in the context of a victim's browser session. This vulnerability is remotely exploitable without requiring authentication, although user interaction is necessary to trigger the malicious payload. The CVSS 4.0 base score is 4.8, indicating a medium severity level. The attack vector is network-based with low attack complexity, and no privileges are required, but user interaction is needed. The vulnerability impacts confidentiality to a limited extent and integrity to a low extent, with no direct impact on availability. The vendor was notified but has not responded or issued a patch, and public exploit details have been disclosed, increasing the risk of exploitation. The vulnerability affects a specific function within the intranet module, which suggests that exploitation may be limited to users with access to the intranet interface, potentially internal staff or students. However, given the remote exploitability and public disclosure, attackers could craft phishing or social engineering campaigns to trick users into executing malicious scripts, leading to session hijacking, credential theft, or unauthorized actions within the i-Educar platform.
