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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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

Definitions: FIRST CVSS v4.0 specification.

Exploitation evidence

Disclosed: evidence found.
CVE published 31 Jul 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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.

AI-suggested

Given the absence of an official patch, European organizations should implement several targeted mitigations: 1) Apply strict input validation and output encoding at the application or web server level, using web application firewalls (WAFs) configured to detect and block malicious payloads targeting the 'campo_busca' and 'cpf' parameters. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the i-Educar application. 3) Limit access to the vulnerable intranet page by network segmentation and IP whitelisting, ensuring only trusted users can reach the affected endpoint. 4) Educate users about the risks of clicking suspicious links and implement browser security features such as anti-XSS extensions. 5) Monitor logs for unusual input patterns or repeated attempts to exploit the vulnerability. 6) Consider deploying reverse proxies or application gateways that can sanitize inputs before reaching the application. 7) Plan for an upgrade or migration to a patched or alternative solution once available, and maintain communication with the vendor for updates.

Description

A vulnerability classified as problematic was found in Portabilis i-Educar 2.9. This vulnerability affects unknown code of the file /intranet/pesquisa_pessoa_lst.php. The manipulation of the argument campo_busca/cpf 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 2.9, particularly educational institutions managing sensitive student and staff data, this vulnerability poses a significant risk. Successful exploitation could lead to theft of session cookies, enabling attackers to impersonate users and access confidential information such as personal identification data, academic records, and internal communications. This could result in data breaches violating GDPR regulations, leading to legal and financial repercussions. Additionally, attackers might perform unauthorized actions within the application, potentially disrupting educational operations or escalating privileges. The remote exploitability without authentication increases the attack surface, especially if the affected systems are accessible over the internet or within intranet environments with insufficient network segmentation. The lack of vendor response and patches exacerbates the risk, as organizations must rely on alternative mitigations to protect their environments.
