CVE-2025-22133 is a critical vulnerability affecting WeGIA, a web manager designed for charitable institutions. The vulnerability is found in the /WeGIA/html/socio/sistema/controller/controla_xlsx.php endpoint, which fails to validate file uploads properly. This oversight permits the upload of malicious files, such as .phar, which can subsequently be executed by the server.
With a CVSS score of 9.9, this vulnerability is classified as critical. Organizations utilizing WeGIA should be particularly concerned, as the potential for exploitation is high due to the low complexity of the attack. The issue has been addressed in version 3.2.8, which contains the necessary security improvements.
Risk to organizations includes unauthorized access to sensitive data and potential server compromise. Given the nature of the vulnerability, the urgency for defenders to apply the patch is critical to mitigate risks associated with file upload flaws.
Currently, there are no confirmed public exploits available, but the nature of this vulnerability suggests that attackers may leverage it to execute arbitrary code remotely. Organizations should prioritize patching immediately.
For further information on patching and remediation strategies, organizations are encouraged to refer to relevant security advisories.
Vulnerability Details
The vulnerability allows the upload of malicious files due to insufficient validation on the endpoint. This issue is categorized under CWE-94 (Code Injection) and CWE-434 (Unrestricted Upload of File with Dangerous Type).
The CVSS score of 9.9 indicates a critical severity level, highlighting the potential impact on confidentiality, integrity, and availability.
The vulnerability affects all versions of WeGIA prior to 3.2.8, with the remediation available in the latest release.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of file types that can be uploaded to the server. The attack vector is network-based, allowing an attacker to exploit the vulnerability remotely.
The attack complexity is low, requiring only basic knowledge of how to upload files. Privileges required to exploit the vulnerability are low, meaning that any user can potentially perform the attack without advanced skills.
User interaction is not required for exploitation, which significantly increases the risk. If successful, the attacker could gain high-level access, severely impacting confidentiality, integrity, and availability.
Risk & Impact Analysis
The potential for unauthorized access to sensitive data raises serious concerns for organizations using WeGIA. The blast radius of this vulnerability is considerable, as it affects any system running the vulnerable versions.
Organizations should assess the risk based on their operational context and the data handled by WeGIA. Given the high CVSS score, this vulnerability should be addressed in priority patch cycles. The urgency for action is critical to prevent exploitation.
