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

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 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 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

European organizations should implement specific mitigations beyond generic advice: 1) Deploy Web Application Firewalls (WAFs) with rules targeting reflected XSS patterns, particularly filtering or blocking suspicious input in the 'q' parameter of the /alunos/search_autocomplete endpoint. 2) Apply strict Content Security Policies (CSP) to restrict script execution sources and reduce the impact of injected scripts. 3) Conduct input validation and output encoding at the application layer if source code access is available, or engage with Portabilis for custom patches or updates. 4) Educate users about phishing and suspicious links to reduce the likelihood of successful social engineering exploitation. 5) Monitor web server logs for unusual requests targeting the vulnerable endpoint and implement anomaly detection to identify exploitation attempts. 6) If feasible, isolate the i-Diario application within a segmented network zone to limit lateral movement in case of compromise. 7) Regularly review and update incident response plans to include scenarios involving XSS exploitation and data leakage. These targeted actions will help reduce the attack surface and mitigate the risk until an official patch is released.

Description

A vulnerability was determined in Portabilis i-Diario up to 1.5.0. This impacts an unknown function of the file /alunos/search_autocomplete. Executing manipulation of the argument q can lead to cross site scripting. The attack may be performed from a remote location. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using Portabilis i-Diario, particularly educational institutions or administrative bodies that rely on this software for student management, this vulnerability poses a risk of client-side attacks that can compromise user sessions and data confidentiality. Successful exploitation could lead to unauthorized access to user accounts, leakage of sensitive student information, or manipulation of displayed data. While the vulnerability does not directly affect system availability, the reputational damage and potential regulatory consequences under GDPR for data breaches could be significant. The risk is heightened in environments where users have elevated privileges or where the software is integrated with other sensitive systems. Additionally, since the vendor has not provided a patch, organizations may face prolonged exposure. The medium severity suggests that while the threat is not critical, it should not be ignored, especially given the public disclosure and ease of remote exploitation without authentication.

Summary

CVE-2025-9107 is a cross-site scripting (XSS) vulnerability identified in the Portabilis i-Diario software versions up to 1.5.0. The vulnerability arises from improper handling of the 'q' parameter in the /alunos/search_autocomplete endpoint. An attacker can craft malicious input for this parameter, which is then reflected in the web application's response without adequate sanitization or encoding, enabling the execution of arbitrary scripts in the context of the victim's browser. This vulnerability is remotely exploitable without requiring authentication, although it requires user interaction to trigger the malicious payload (e.g., a victim clicking a crafted link). The CVSS 4.0 base score is 5.3, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges or user authentication needed. The impact primarily affects confidentiality and integrity to a limited extent, as the vulnerability allows script execution that could lead to session hijacking, credential theft, or defacement, but does not directly compromise availability or system-level access. The vendor has been notified but has not responded or issued a patch, and no known exploits have been observed in the wild yet. Given the public disclosure and the nature of XSS vulnerabilities, exploitation is plausible especially in environments where users are less security-aware or where the affected software is widely deployed without mitigations such as Content Security Policy (CSP).
