CVE-2025-34430 is a Cross-Site Request Forgery (CSRF) vulnerability identified in LXware's 1Panel product, specifically affecting versions from 1.10.33 through 2.0.15. The vulnerability resides in the panel name management functionality where the web endpoint responsible for changing the panel name does not implement standard CSRF defenses such as anti-CSRF tokens or validation of the Origin or Referer HTTP headers. This absence allows an attacker to craft 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 processed successfully without the victim's consent or awareness. The attack vector requires user interaction (visiting the malicious page) but does not require the attacker to have any privileges or authentication. The impact is limited to unauthorized modification of the panel name, which could be leveraged for social engineering, misdirection, or to undermine trust in the system's interface. The CVSS 4.0 base score is 5.1 (medium severity), reflecting the network attack vector, low complexity, no privileges required, but requiring user interaction and limited impact on integrity only. No patches or exploits are currently reported, but the vulnerability is publicly disclosed and should be addressed promptly.

For European organizations using LXware 1Panel, this vulnerability poses a risk primarily to the integrity of the panel's configuration interface. Unauthorized changes to the panel name could confuse administrators or users, potentially facilitating phishing or social engineering attacks by misleading users about the system's identity or status. While the vulnerability does not directly compromise confidentiality or availability, it can undermine trust in the management interface and may serve as a stepping stone for more sophisticated attacks if combined with other vulnerabilities or social engineering techniques. Organizations with web-facing 1Panel instances are at higher risk, especially if users frequently access the panel from browsers susceptible to CSRF attacks. The medium severity indicates a moderate risk that should be mitigated to maintain operational security and user trust.

1. Implement immediate compensating controls such as web application firewalls (WAFs) to detect and block CSRF attack patterns targeting the panel name change endpoint. 2. Enforce strict Content Security Policy (CSP) headers to reduce the risk of malicious script execution from untrusted sources. 3. Educate users and administrators to avoid clicking on suspicious links or visiting untrusted websites while authenticated to the 1Panel. 4. If possible, restrict access to the 1Panel interface to trusted IP ranges or VPN-only access to reduce exposure. 5. Monitor web server logs for unusual POST requests to the panel name management endpoint that could indicate exploitation attempts. 6. Advocate for or develop patches that implement anti-CSRF tokens and validate Origin or Referer headers on the affected endpoints. 7. Regularly update and audit the 1Panel software to incorporate security fixes once available. 8. Consider multi-factor authentication (MFA) for panel access to reduce the risk of session hijacking that could compound this vulnerability.
