A vulnerability was found in Facile Sistemas Cloud Apps up to 20250107. It has been classified as problematic. Affected is an unknown function of the file /account/forgotpassword of the component Password Reset Handler. The manipulation of the argument reterros leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
This vulnerability has a CVSS score of 5.3, indicating a medium severity. The risk to organizations includes potential unauthorized access and data exposure through cross-site scripting attacks. Given the exploit's public disclosure, organizations should prioritize patching immediately.
Organizations must assess their usage of Facile Sistemas Cloud Apps and implement necessary remediation measures. The urgency for defenders is heightened due to the nature of the vulnerability and its exploitability.
The vulnerability was published on January 20, 2025, and has been categorized under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code ('Code Injection')).
Vulnerability Details
The vulnerability allows for cross site scripting due to improper handling of the 'reterros' argument in the password reset handler. The CVSS v4.0 metrics indicate an attack vector of NETWORK, low attack complexity, and low privileges required for exploitation. The integrity impact is classified as low, while confidentiality and availability impacts are rated as none.
Technical Analysis
Root cause analysis highlights a failure to properly sanitize user-supplied input in the password reset functionality. This oversight allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to account takeover and data theft.
The attack vector is primarily network-based, requiring no user interaction, which increases the likelihood of successful exploitation. Attack complexity is low, as an attacker only needs to craft a malicious URL and share it with a target user.
The impacts on confidentiality are none, as the attack does not directly expose sensitive information. However, integrity can be compromised, allowing the attacker to manipulate web content and potentially redirect users to malicious sites.
Risk & Impact Analysis
Real-world deployment risk is significant, especially for organizations relying on the Facile Sistemas Cloud Apps for user account management. The potential for cross-site scripting attacks can lead to severe consequences, including data breaches and loss of user trust.
The blast radius is substantial, as this vulnerability can affect all users of the application, making it a critical concern for security teams. Organizations should address this vulnerability in their priority patch cycle to minimize the risk exposure.
Given the CVSS score of 5.3 and the public disclosure of the exploit, organizations should prioritize remediation efforts. The low EPS score indicates a low likelihood of widespread exploitation, but the potential impact remains significant.
