CVE-2025-30901 is a Local File Inclusion (LFI) vulnerability found in the JoomSky JS Help Desk plugin, specifically versions up to and including 2.9.2. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input to include arbitrary files from the local filesystem on the web server. By exploiting this vulnerability, an attacker can read sensitive files such as configuration files, password files, or application source code, potentially leading to information disclosure. In some cases, LFI can be leveraged to execute arbitrary code if combined with other vulnerabilities or misconfigurations. The vulnerability does not require authentication, increasing its risk, and can be triggered remotely if the vulnerable endpoint is exposed to the internet. Although no public exploits have been reported yet, the nature of the vulnerability and the widespread use of PHP-based CMS systems make it a significant threat. The lack of a CVSS score indicates that the vulnerability is newly published and awaiting further analysis. The vulnerability affects organizations using the JS Help Desk plugin, which is integrated into websites to provide customer support ticketing functionality. Without proper patching or mitigation, attackers can exploit this vulnerability to compromise the confidentiality and integrity of affected systems.

The impact of CVE-2025-30901 can be severe for organizations using the JS Help Desk plugin. Successful exploitation can lead to unauthorized disclosure of sensitive information such as credentials, configuration files, and internal application data. This can facilitate further attacks including privilege escalation, remote code execution, or lateral movement within the network. The vulnerability undermines the confidentiality and integrity of the affected systems and may also impact availability if attackers manipulate files critical to application operation. Organizations relying on JS Help Desk for customer support risk exposure of sensitive customer data and internal communications. The ease of exploitation without authentication increases the threat level, especially for publicly accessible web servers. The absence of known exploits currently provides a window for remediation, but attackers may develop exploits rapidly given the straightforward nature of LFI vulnerabilities. The overall risk is heightened for organizations with poor patch management or insufficient web application security controls.

To mitigate CVE-2025-30901, organizations should prioritize updating the JS Help Desk plugin to a version where the vulnerability is patched once available from the vendor. Until an official patch is released, implement strict input validation to ensure that user-supplied parameters controlling file inclusion cannot be manipulated to reference arbitrary files. Employ whitelisting of allowed filenames and sanitize inputs to remove directory traversal characters and null bytes. Configure the PHP environment to disable dangerous functions such as allow_url_include and restrict file system permissions to limit access to sensitive files. Use web application firewalls (WAFs) to detect and block suspicious requests targeting include/require parameters. Conduct thorough code reviews and penetration testing focused on file inclusion vulnerabilities. Additionally, monitor logs for unusual access patterns indicative of exploitation attempts. Segmentation of web servers and limiting exposure of the JS Help Desk interface to trusted networks can further reduce risk. Finally, maintain regular backups and incident response plans to quickly recover from potential compromises.
