CVE-2025-23036 is a medium-severity reflected Cross-Site Scripting (XSS) vulnerability affecting WeGIA, an open-source web manager tailored for Portuguese-speaking charitable organizations. The vulnerability is found in the `pre_cadastro_funcionario.php` endpoint, where the application fails to validate and sanitize user inputs in the `msg_e` parameter. This oversight allows attackers to inject malicious scripts, which are then reflected back to users' browsers and executed within their context.
The CVSS score for this vulnerability is 6.4, indicating a medium level of severity. The attack vector is classified as network-based, with low attack complexity and no privileges required for exploitation. User interaction is required, which means that a user must click on a link or perform an action that triggers the exploit. The potential impacts on confidentiality and integrity are low, but the vulnerability poses a significant risk as it can lead to the execution of arbitrary scripts within the victim's browser.
Organizations using WeGIA must prioritize upgrading to version 3.2.7, which addresses this vulnerability. There are currently no known workarounds to mitigate the risk posed by this issue, making patching essential.
Given the nature of XSS vulnerabilities and their potential to facilitate further attacks, organizations should assess their exposure and take immediate action to apply the necessary updates.
Vulnerability Details
The reflected XSS vulnerability in WeGIA is characterized by the inability of the application to properly validate and sanitize user input. Specifically, the `msg_e` parameter in the `pre_cadastro_funcionario.php` endpoint is susceptible to malicious script injections. This flaw was identified and disclosed on January 14, 2025, with the recommended fix provided in version 3.2.7.
The vulnerability is classified under CWE-79, which pertains to Improper Neutralization of Input During Web Page Generation (Cross-site Scripting). Organizations should take note that the exploit may lead to various consequences, including unauthorized data access or manipulation.
Technical Analysis
The root cause of the vulnerability lies in the inadequate input validation of the `msg_e` parameter, allowing attackers to inject harmful scripts. The attack vector is network-based, which means the attacker could exploit it from any location with internet access.
The attack complexity is rated as low, as no special conditions or skills are required to exploit this vulnerability. However, it does require user interaction, as the victim must click on a link containing the malicious payload.
The confidentiality impact is low, as the vulnerability does not directly expose sensitive information. However, the integrity impact is also low, as it allows for the execution of arbitrary scripts without compromising the underlying data. The availability impact is none, meaning the attack does not disrupt service.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized script execution within users' browsers, leading to phishing attacks, session hijacking, or redirecting users to malicious sites. The vulnerability's medium CVSS score indicates a notable risk that should not be overlooked.
The lack of known workarounds amplifies the urgency for organizations to apply the patch to version 3.2.7. Not addressing this vulnerability increases the likelihood of exploitation, especially in environments where user interaction is common.
Organizations should assess their deployment of WeGIA and the potential for exposure to this vulnerability. Given the nature of web applications and user interactions, the blast radius of exploitation could affect multiple users within an organization.

Affected Versions
The vulnerable versions of WeGIA are all versions prior to 3.2.7. Organizations using earlier versions should upgrade promptly to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should upgrade to WeGIA version 3.2.7 to address the reflected XSS vulnerability. It is crucial to validate and sanitize all user inputs, particularly in sensitive parameters like `msg_e`. Regular security reviews and penetration testing can help identify similar vulnerabilities in the future.
For ongoing security, organizations might consider implementing continuous penetration testing to ensure that new vulnerabilities are identified and mitigated in a timely manner.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual entries related to the `msg_e` parameter. Behavioral anomalies, such as unexpected scripts being executed or unauthorized access attempts, should be flagged for further investigation.
