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

Exploitation evidence

Disclosed: evidence found.
CVE published 3 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
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

Organizations should implement specific mitigations beyond generic advice: 1) Immediately restrict access to the vulnerable intranet page (/intranet/educar_avaliacao_desempenho_cad.php) via network controls or web application firewalls (WAF) with rules to detect and block suspicious input patterns in the titulo_avaliacao and descricao parameters. 2) Conduct user awareness training focused on phishing and social engineering to reduce the risk of user interaction with malicious links. 3) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers accessing the i-Educar system. 4) Monitor web server and application logs for unusual parameter values or repeated attempts to exploit the vulnerability. 5) If possible, apply input validation or sanitization at the application level by customizing or patching the affected PHP file, even if an official patch is unavailable. 6) Segment the network to isolate the i-Educar system from other critical infrastructure to limit lateral movement. 7) Regularly back up critical data and verify restoration procedures to mitigate potential data integrity issues.

Description

A vulnerability was found in Portabilis i-Educar 2.9. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /intranet/educar_avaliacao_desempenho_cad.php. The manipulation of the argument titulo_avaliacao/descricao leads to cross site scripting. The attack can be launched 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, this XSS vulnerability poses a risk primarily to the confidentiality and integrity of user sessions and data. Exploitation could lead to unauthorized access to user accounts, session hijacking, and potential data manipulation within the educational management system. This could disrupt academic operations, compromise student and staff personal information, and damage institutional reputation. Since the vulnerability requires user interaction and is exploitable remotely, phishing campaigns targeting staff or students could be effective. The lack of vendor response and patch availability increases exposure time. Educational institutions in Europe that rely on i-Educar for managing evaluations and performance data are particularly vulnerable, potentially affecting data privacy compliance under GDPR if personal data is compromised. Additionally, attackers could use the vulnerability as a foothold to pivot to other internal systems if network segmentation is weak.
