A vulnerability was found in Zenvia Movidesk up to version 25.01.22, rated as problematic. The vulnerability affects some unknown functionality of the file /Account/EditProfile within the Profile Editing component. Manipulation of the argument username leads to cross-site scripting (XSS), potentially allowing attackers to execute malicious scripts in the context of users' browsers. The attack can be launched remotely, making it a significant concern. An exploit has been publicly disclosed, which could be leveraged by malicious actors. Therefore, organizations using this software should prioritize patching immediately by upgrading to version 25.01.22.245a473c54.
Given the medium severity score of 5.3 according to the CVSS v4.0, this vulnerability poses a moderate risk to organizations. The attack vector is network-based, and the attack complexity is low, which means that attackers with minimal skills can exploit this vulnerability. The urgency for defenders is high, as the potential for malicious exploitation is real and could lead to significant security incidents.
Organizations should assess their exposure to this vulnerability and take necessary actions to protect their systems. This includes reviewing their deployment of Zenvia Movidesk and ensuring that they are running the latest patched version. Failure to do so may result in unauthorized access and data breaches.
In addition to upgrading, implementing security best practices such as input validation, output encoding, and regular security audits can help mitigate risks associated with XSS vulnerabilities. Security teams should also monitor for any signs of exploitation attempts targeting this vulnerability.
Vulnerability Details
As described, the vulnerability impacts Zenvia Movidesk up to version 25.01.22, allowing for cross-site scripting (CWE-79) and potentially remote code execution (CWE-94). The CVSS v3.1 score of 5.4 confirms the medium severity level, emphasizing the need for immediate remediation.
Technical Analysis
The root cause of this vulnerability lies in insufficient input validation, specifically regarding the username parameter. When manipulated, it allows execution of arbitrary JavaScript in the user's browser, which can lead to session hijacking or defacement of web applications. The attack vector is network-based, requiring no user interaction for exploitation, while the complexity remains low due to the nature of the attack.
Risk & Impact Analysis
The real-world deployment risk is significant for organizations utilizing Zenvia Movidesk. If exploited, the potential for unauthorized access to sensitive user data is high, leading to reputational damage and financial losses. Given the medium CVSS score and the fact that the vulnerability is not included in the KEV catalog, organizations should prioritize their patching efforts in their security cycles.
