CVE-2025-10085 is a security vulnerability identified in SourceCodester Pet Grooming Management Software version 1.0. The flaw resides in the file manage_website.php, where an unrestricted file upload vulnerability exists. This vulnerability allows an attacker to remotely upload arbitrary files to the server without proper validation or restrictions. The lack of controls on the file upload mechanism can enable attackers to upload malicious scripts or executables, potentially leading to remote code execution, server compromise, or unauthorized access to sensitive data. The vulnerability requires no user interaction and can be exploited remotely with low attack complexity and no privileges required. The CVSS 4.0 base score is 5.3, indicating a medium severity level. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as the vector components indicate low impact on these aspects but with potential for exploitation. Although no public exploit is confirmed in the wild, proof-of-concept code has been released, increasing the risk of exploitation. No official patches or mitigations have been published by the vendor at this time, increasing the urgency for organizations to implement compensating controls.

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this vulnerability poses a moderate risk. Exploitation could lead to unauthorized file uploads, enabling attackers to execute arbitrary code on affected servers. This could result in data breaches, service disruptions, or further lateral movement within the network. Given that pet grooming businesses may handle customer personal information and payment data, a compromise could lead to privacy violations under GDPR, resulting in regulatory penalties and reputational damage. Additionally, if the software is hosted on shared infrastructure or integrated with other business systems, the impact could extend beyond the immediate application. The medium severity rating suggests that while the vulnerability is exploitable, the overall damage might be contained if proper network segmentation and monitoring are in place. However, the public availability of exploit code increases the likelihood of opportunistic attacks, especially targeting smaller businesses with limited cybersecurity resources.

Since no official patch is currently available, European organizations should implement immediate compensating controls. These include restricting access to the manage_website.php file through web server configuration (e.g., IP whitelisting, authentication enforcement), disabling file upload functionality if not essential, or implementing strict file type and size validation at the web server or application firewall level. Deploying a Web Application Firewall (WAF) with custom rules to detect and block malicious upload attempts can reduce risk. Regularly monitoring web server logs for unusual upload activity and scanning uploaded files for malware is critical. Organizations should also isolate the application server from critical network segments to limit potential lateral movement. Finally, organizations should maintain up-to-date backups and prepare incident response plans to quickly remediate any compromise. Engaging with the vendor for patch timelines and subscribing to vulnerability advisories is recommended to apply official fixes once available.
