CVE-2025-52708 is a high-severity vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the RealMag777 HUSKY product, versions up to and including 1.3.7. The flaw allows for PHP Local File Inclusion (LFI), meaning an attacker can manipulate the filename parameter in PHP include or require statements to execute arbitrary local files on the server. This can lead to the execution of malicious code, disclosure of sensitive information, or full system compromise depending on the privileges of the web server process. The vulnerability is exploitable remotely over the network (AV:N) but requires a high attack complexity (AC:H), meaning that exploitation is not trivial and may require specific conditions or knowledge. It requires low privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), indicating the vulnerability affects only the vulnerable component. The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), reflecting the potential for significant damage if exploited. No patches or known exploits are currently documented, but the vulnerability is publicly disclosed as of June 20, 2025. The absence of patches increases the urgency for mitigation. The vulnerability arises from insufficient validation or sanitization of input controlling the filename in include/require statements, a common PHP security pitfall that can lead to arbitrary file inclusion and code execution.

For European organizations using RealMag777 HUSKY up to version 1.3.7, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive data, including intellectual property, personal data protected under GDPR, and internal configuration files. The ability to execute arbitrary code could allow attackers to establish persistent backdoors, pivot within networks, or disrupt services, impacting business continuity and reputation. Given the high impact on confidentiality, integrity, and availability, organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk. The high attack complexity somewhat limits widespread exploitation but does not eliminate risk, especially from skilled threat actors. The lack of known exploits in the wild currently provides a window for proactive defense, but the public disclosure increases the likelihood of future exploitation attempts. Additionally, the vulnerability could be leveraged in targeted attacks or ransomware campaigns, which have been increasingly prevalent in Europe.

1. Immediate mitigation should include disabling or restricting the use of dynamic include/require statements that accept user input in HUSKY configurations or custom code. 2. Implement strict input validation and sanitization to ensure that only allowed filenames or paths are processed. Use whitelisting approaches rather than blacklisting. 3. Employ PHP configuration directives such as 'open_basedir' to restrict file system access to designated directories, limiting the scope of file inclusion. 4. Run the web server and PHP processes with the least privileges necessary to minimize the impact of a successful exploit. 5. Monitor web application logs for unusual include/require parameter values or errors indicative of attempted exploitation. 6. If possible, isolate the HUSKY application in a container or sandbox environment to contain potential breaches. 7. Engage with RealMag777 or community forums to track the release of official patches or updates addressing this vulnerability and plan for prompt application. 8. Conduct regular security assessments and code reviews focusing on file inclusion mechanisms. 9. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious file inclusion attempts targeting HUSKY endpoints.
