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

Implement strict input validation and output encoding on the nm_tipo parameter to neutralize malicious scripts.
Apply Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers.
Educate users about the risks of clicking unknown or suspicious links, especially within the educational environment.
Monitor web server logs for unusual requests targeting /intranet/educar_turma_tipo_cad.php or containing suspicious payloads.
Segregate the intranet environment to limit exposure to external networks.
Once available, promptly apply official patches or updates from Portabilis addressing this vulnerability.
Employ web application firewalls (WAF) with rules to detect and block XSS attack patterns targeting the affected parameter.
Conduct regular security assessments and code reviews focusing on input handling in web applications.
Ensure session management uses secure cookies with HttpOnly and Secure flags to reduce session hijacking risks.
Maintain up-to-date backups to recover quickly in case of compromise.

Description

A security vulnerability has been detected in Portabilis i-Educar up to 2.10. The affected element is an unknown function of the file /intranet/educar_turma_tipo_cad.php. Such manipulation of the argument nm_tipo leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used.

Impact

For European organizations, especially educational institutions using Portabilis i-Educar, this vulnerability poses a risk of unauthorized access to user sessions and potential data theft. Exploitation could lead to compromised student and staff personal information, unauthorized changes to educational records, and disruption of normal administrative operations. The impact on confidentiality is moderate due to possible session hijacking and data exposure. Integrity could be affected if attackers perform unauthorized actions within the application. Availability is not directly impacted. The vulnerability could also be leveraged as a foothold for further attacks, including phishing campaigns or malware distribution. European organizations with limited cybersecurity awareness or lacking robust input validation controls are particularly vulnerable. The public disclosure and availability of exploit code increase the likelihood of opportunistic attacks, especially targeting less protected institutions.

Summary

CVE-2025-10373 is a cross-site scripting vulnerability identified in Portabilis i-Educar, an open-source educational management system widely used in some regions. The vulnerability resides in the /intranet/educar_turma_tipo_cad.php script, specifically in the handling of the nm_tipo parameter. This parameter is not properly sanitized or encoded, allowing an attacker to inject arbitrary JavaScript code that executes in the context of the victim's browser. The attack vector is remote and does not require authentication, but user interaction is necessary, typically by convincing a user to click a maliciously crafted URL or visit a compromised page. The CVSS 4.0 score of 5.1 reflects a medium severity, considering the ease of exploitation (low complexity, no privileges required), but limited impact on confidentiality and integrity, and no impact on availability. The vulnerability could be exploited to steal session cookies, perform actions on behalf of authenticated users, or deliver further malware payloads. Although no public patches have been linked yet, the presence of public exploit code increases the urgency for mitigation. The vulnerability affects all versions of i-Educar up to 2.10, indicating a broad scope of affected systems. Given i-Educar's use in educational institutions, the threat primarily targets the confidentiality and integrity of user sessions and data within these environments.
