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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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 deploying web application firewalls (WAFs) with custom rules to detect and block malicious input patterns targeting the nm_funcao/abreviatura parameter. Input validation and output encoding should be enforced at the application level if source code access is available, sanitizing user inputs to neutralize script injections. Organizations should also conduct user awareness training to recognize suspicious links and avoid interacting with untrusted sources. Monitoring web server logs for unusual request patterns can help detect exploitation attempts early. Segmentation of the intranet environment and limiting access to the i-Educar application to trusted networks can reduce exposure. Finally, organizations should engage with Portabilis for updates and consider upgrading to newer, secure versions once available.

Description

A vulnerability was found in Portabilis i-Educar 2.9. It has been classified as problematic. Affected is an unknown function of the file /intranet/educar_funcao_lst.php. The manipulation of the argument nm_funcao/abreviatura 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 using Portabilis i-Educar 2.9, particularly educational institutions, this vulnerability poses a significant risk to the confidentiality and integrity of user data. Attackers exploiting this XSS flaw can hijack sessions of administrators or educators, potentially gaining unauthorized access to sensitive student records or internal communications. The reputational damage from a successful attack could be substantial, especially in the education sector where data privacy is critical under GDPR regulations. Additionally, compromised systems could be used to distribute malware or phishing campaigns targeting students and staff. The lack of a vendor patch and public exploit availability increases the urgency for European organizations to address this threat promptly. While availability impact is low, the indirect consequences of data breaches and regulatory penalties could be severe.

Summary

CVE-2025-8507 is a cross-site scripting (XSS) vulnerability identified in Portabilis i-Educar version 2.9, specifically within the /intranet/educar_funcao_lst.php file. The vulnerability arises from improper sanitization of the nm_funcao/abreviatura parameter, allowing an attacker to inject malicious scripts into the web application. This flaw can be exploited remotely without requiring authentication, although user interaction is necessary to trigger the malicious payload (e.g., a victim clicking a crafted link). The vulnerability is classified as medium severity with a CVSS 4.0 base score of 5.1, reflecting its moderate impact and ease of exploitation. The vendor was notified but has not responded or issued a patch, and public exploit code has been disclosed, increasing the risk of exploitation. XSS vulnerabilities like this can lead to session hijacking, credential theft, defacement, or redirection to malicious sites, compromising user confidentiality and integrity. The vulnerability does not affect system availability directly but can be leveraged as a stepping stone for further attacks.
