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

Implement strict input validation and output encoding on the 'nome' parameter in /intranet/public_uf_cad.php to neutralize malicious scripts.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers.
Use web application firewalls (WAFs) with rules targeting common XSS attack patterns to detect and block malicious requests.
Educate users to avoid clicking on suspicious links and report unusual behavior.
Monitor web server logs for unusual parameter values or repeated attempts to exploit this vulnerability.
If possible, isolate the affected module or restrict access to trusted users until a patch is available.
Engage with Portabilis or community forums to track patch releases or unofficial fixes.
Consider upgrading to a newer version if available or applying custom patches to sanitize inputs.

Description

A vulnerability was found in Portabilis i-Educar 2.10. It has been declared as problematic. This vulnerability affects unknown code of the file /intranet/public_uf_cad.php. The manipulation of the argument nome leads to cross site scripting. The attack can be initiated 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, this vulnerability poses a moderate risk primarily to confidentiality and integrity of user sessions and data accessible via the web interface. Educational institutions and administrative bodies relying on i-Educar could face risks of session hijacking, unauthorized actions performed on behalf of users, or exposure of sensitive information through malicious script execution. While the vulnerability does not directly impact system availability, the potential for phishing or social engineering attacks leveraging this XSS flaw could lead to broader security incidents. The lack of vendor response and patch availability increases the window of exposure. European organizations with large user bases or those handling sensitive student data are particularly vulnerable to reputational damage and compliance issues under GDPR if user data is compromised.

Summary

CVE-2025-8541 is a cross-site scripting (XSS) vulnerability identified in version 2.10 of Portabilis i-Educar, an educational management system. The vulnerability resides in the /intranet/public_uf_cad.php file, specifically in the handling of the 'nome' parameter. An attacker can manipulate this parameter to inject malicious scripts that execute in the context of the victim's browser. This type of vulnerability allows remote attackers to perform actions such as stealing session cookies, defacing web content, or redirecting users to malicious sites. The vulnerability does not require authentication but does require user interaction (e.g., the victim must visit a crafted URL). The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H is unusual but likely a typo or means high privileges required), user interaction required (UI:P), and limited impact on integrity (VI:L) with no impact on confidentiality or availability. The vendor was notified but did not respond, and no patches have been released yet. Although the exploit has been publicly disclosed, there are no known exploits actively used in the wild at this time.
