CVE-2025-34430 is a cross-site request forgery (CSRF) vulnerability identified in LXware's 1Panel software, specifically affecting versions from 1.10.33 through 2.0.15. The vulnerability resides in the panel name management functionality, where the HTTP endpoint responsible for changing the panel name does not implement standard CSRF mitigations such as anti-CSRF tokens or validation of the Origin or Referer HTTP headers. This absence allows an attacker to create a malicious webpage that silently submits a request to change the panel name when visited by an authenticated user. Because the victim's browser automatically includes valid session cookies, the request is accepted and processed by the server, resulting in an unauthorized change of the panel name. The vulnerability requires no authentication or privileges beyond the victim's active session and only requires user interaction in the form of visiting a crafted webpage. The CVSS v4.0 base score is 5.1, reflecting medium severity, with the vector indicating network attack vector, low attack complexity, no privileges required, user interaction required, and limited impact on integrity. While no public exploits are known, the vulnerability could be leveraged for social engineering or to cause confusion by altering panel names, potentially impacting administrative workflows or trust in the interface. The lack of CSRF protections is a common web security oversight, and remediation involves implementing anti-CSRF tokens or validating Origin/Referer headers to ensure requests are legitimate.

The primary impact of this vulnerability is unauthorized modification of the panel name within LXware 1Panel, which could lead to confusion among administrators or users relying on the panel for management tasks. Although the direct confidentiality, integrity, and availability impacts are limited—since the vulnerability only allows changing the panel name and not more critical settings—it can be exploited as part of a broader social engineering or phishing campaign. For example, an attacker could rename the panel to mislead users or hide malicious activity. Organizations relying on 1Panel for infrastructure or service management may experience operational disruptions or reduced trust in their management interfaces. Since exploitation requires user interaction but no elevated privileges, the attack surface includes any authenticated user visiting a malicious webpage. The vulnerability does not appear to allow privilege escalation or data exfiltration directly, but it weakens the security posture by permitting unauthorized changes to the management interface.

To mitigate this vulnerability, organizations should implement robust CSRF protections on the affected endpoint. This includes adding anti-CSRF tokens that are validated on the server side for all state-changing requests, ensuring that requests originate from legitimate sources. Additionally, validating the Origin and Referer HTTP headers can provide an extra layer of defense against CSRF attacks. If possible, upgrading to a patched version of LXware 1Panel that addresses this vulnerability is the most effective mitigation; if no patch is available, consider applying custom web application firewall (WAF) rules to detect and block suspicious requests targeting the panel name change endpoint. Educate users to avoid visiting untrusted websites while authenticated to the panel, and monitor logs for unexpected panel name changes to detect potential exploitation attempts. Regular security assessments and penetration testing should include checks for CSRF vulnerabilities to prevent similar issues.
