CVE-2022-24227 is a cross-site scripting (XSS) vulnerability affecting BoltWire versions 7.10 and 8.00. This vulnerability arises due to insufficient input sanitization or output encoding in the handling of the 'name' and 'lastname' parameters within the web application. An attacker can craft malicious payloads containing arbitrary web scripts or HTML and inject them into these parameters. When a victim user accesses the affected page or functionality, the malicious script executes in their browser context. This can lead to theft of session cookies, user impersonation, defacement, or redirection to malicious sites. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The CVSS v3.1 base score is 6.1, indicating a medium severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network without privileges, requires low attack complexity, no privileges, but does require user interaction (victim must click or visit a crafted link). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component, and it impacts confidentiality and integrity to a limited extent but does not affect availability. No known exploits in the wild have been reported, and no official patches or vendor information are provided in the data. The vulnerability affects a specific CMS or web application platform called BoltWire, which is used for website content management and publishing.

For European organizations using BoltWire CMS versions 7.10 or 8.00, this vulnerability poses a risk of client-side attacks that can compromise user sessions and data confidentiality. Attackers could exploit this XSS flaw to steal authentication cookies or tokens, enabling unauthorized access to user accounts or administrative functions. This could lead to unauthorized content modification, data leakage, or further exploitation within the organization's web infrastructure. The impact is particularly significant for organizations handling sensitive user data, such as e-commerce sites, government portals, or healthcare providers. Additionally, the vulnerability could be leveraged for phishing campaigns by injecting malicious scripts that mimic legitimate content, increasing the risk of social engineering attacks. Given the medium severity and requirement for user interaction, the threat is moderate but should not be underestimated, especially in sectors with high regulatory compliance requirements like GDPR. The lack of patches or vendor guidance increases the risk window for European entities relying on these versions of BoltWire.

1. Immediate mitigation should include implementing strict input validation and output encoding on the 'name' and 'lastname' parameters to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Use HTTP-only and Secure flags on cookies to prevent theft via client-side scripts. 4. Educate users to avoid clicking on suspicious links or inputs that could trigger the XSS payload. 5. If possible, upgrade to a newer, patched version of BoltWire or apply community-sourced patches or workarounds that sanitize inputs. 6. Conduct regular security audits and penetration testing focusing on input handling in web applications. 7. Monitor web server logs and user reports for signs of exploitation attempts or anomalous behavior. 8. Consider implementing Web Application Firewalls (WAF) with rules to detect and block XSS payloads targeting the affected parameters. These steps go beyond generic advice by focusing on specific parameters and leveraging layered defenses.
