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 endpoint responsible for changing the panel name does not implement standard CSRF protections 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, when visited by an authenticated user of the 1Panel interface, causes the victim's browser to send a forged request including valid session cookies. Consequently, the attacker can change the panel name to an arbitrary value without the user's knowledge or consent. The attack vector requires user interaction (visiting the malicious page) but does not require the attacker to have any privileges or authentication. The vulnerability has been assigned a CVSS 4.0 score of 5.1, reflecting a medium severity level due to its moderate impact on integrity and the need for user interaction. No public exploits or patches have been reported as of the publication date. The vulnerability could be leveraged as part of a broader attack chain, potentially enabling social engineering, phishing, or undermining trust in the management interface. The lack of CSRF defenses indicates a design oversight in the affected versions of 1Panel, highlighting the need for secure development lifecycle practices. Organizations using 1Panel should be aware of this vulnerability and prepare to implement mitigations or updates once available.

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of the 1Panel management interface. Unauthorized changes to the panel name could lead to confusion among administrators, potential misconfiguration, or serve as a foothold for further social engineering or phishing attacks targeting administrators. While the vulnerability does not directly compromise confidentiality or availability, the manipulation of management interface elements can undermine trust and operational control. Organizations with publicly accessible or insufficiently protected 1Panel interfaces are at higher risk, as attackers can lure authenticated users to malicious sites to trigger the CSRF attack. Sectors relying on LXware 1Panel for critical infrastructure management or hosting services could face reputational damage or operational disruptions if attackers exploit this vulnerability to cause misconfigurations or facilitate subsequent attacks. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

To mitigate CVE-2025-34430, organizations should implement the following specific measures: 1) Restrict access to the 1Panel management interface using network-level controls such as IP whitelisting, VPNs, or firewall rules to limit exposure to trusted users only. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF-like requests or anomalous POST requests to the panel name management endpoint. 3) Encourage users to avoid visiting untrusted websites while authenticated to 1Panel to reduce the risk of CSRF exploitation. 4) Monitor logs and configuration changes for unexpected panel name modifications to detect potential exploitation attempts early. 5) Advocate for or develop patches that introduce anti-CSRF tokens and validate Origin or Referer headers on the affected endpoints, and apply these updates promptly once available. 6) Conduct security awareness training for administrators emphasizing the risks of CSRF and safe browsing practices. 7) Consider implementing multi-factor authentication (MFA) for the 1Panel interface to reduce the impact of session hijacking or unauthorized access. These targeted mitigations go beyond generic advice by focusing on access control, detection, and user behavior specific to the nature of this vulnerability.
