Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 14 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

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 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

European organizations using WeGIA should immediately upgrade to version 3.4.5 or later, which contains the official patch for this vulnerability. If upgrading is not immediately feasible, organizations should implement input validation and output encoding on the 'erro' parameter to neutralize potentially malicious scripts. Web Application Firewalls (WAFs) can be configured with custom rules to detect and block suspicious payloads targeting the 'erro' parameter. Additionally, organizations should conduct user awareness training to reduce the risk of users clicking on malicious links, emphasizing caution with unsolicited URLs. Regular security assessments and penetration testing should include checks for XSS vulnerabilities. Monitoring web server logs for unusual requests to 'index.php' with suspicious 'erro' parameter values can help detect exploitation attempts. Finally, implementing Content Security Policy (CSP) headers can mitigate the impact of XSS by restricting the execution of unauthorized scripts in browsers.

Description

WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. A Reflected Cross-Site Scripting (XSS) vulnerability was identified in the `index.php` endpoint of the WeGIA application prior to version 3.4.5. This vulnerability allows attackers to inject malicious scripts in the `erro` parameter. Version 3.4.5 contains a patch for the issue.

Impact

For European organizations using WeGIA, particularly those in the charitable sector or Portuguese-speaking communities, this vulnerability poses a significant risk to confidentiality. Attackers could leverage the XSS flaw to steal session tokens or other sensitive data, enabling unauthorized access to user accounts or administrative functions. This could lead to data breaches involving donor information, financial data, or internal communications. Additionally, successful exploitation could facilitate phishing attacks or malware distribution by injecting malicious scripts into trusted web pages. Although the vulnerability does not directly affect integrity or availability, the loss of confidentiality and potential subsequent attacks could disrupt organizational operations and damage reputation. Given the focus on charitable institutions, which may have limited cybersecurity resources, the impact could be more pronounced. Furthermore, the requirement for user interaction means social engineering or targeted phishing campaigns could be used to increase exploitation success. The medium severity score reflects these factors but also indicates that the threat should not be underestimated, especially in environments with high-value data or critical services.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
