CVE-2025-10428 is a medium-severity security vulnerability affecting SourceCodester Pet Grooming Management Software version 1.0. The vulnerability exists in the /admin/seo_setting.php file, specifically within an unknown function handling the 'website_image' argument. This flaw allows an attacker to perform an unrestricted file upload remotely without requiring authentication or user interaction. By exploiting this vulnerability, an attacker can upload arbitrary files, potentially including malicious scripts or executables, to the server hosting the application. This could lead to remote code execution, unauthorized access, or further compromise of the affected system. The CVSS 4.0 base score is 5.3, reflecting a network attack vector with low attack complexity and no privileges or user interaction required, but with limited impact on confidentiality, integrity, and availability. No official patches or fixes have been published yet, and while no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation.

For European organizations using SourceCodester Pet Grooming Management Software 1.0, this vulnerability poses a tangible risk of unauthorized system compromise. Successful exploitation could allow attackers to upload malicious payloads, leading to potential data breaches, service disruption, or pivoting within internal networks. Given that the software is targeted at pet grooming businesses, which may handle customer personal data and payment information, confidentiality and integrity of sensitive data could be jeopardized. Additionally, compromised systems could be leveraged to launch further attacks or distribute malware. The lack of authentication requirements for exploitation increases the threat level, especially for organizations with externally accessible administrative interfaces. This vulnerability could also damage organizational reputation and lead to regulatory non-compliance under GDPR if personal data is exposed.

Organizations should immediately audit their deployments of SourceCodester Pet Grooming Management Software to identify affected versions. Until an official patch is released, practical mitigations include restricting access to the /admin/seo_setting.php endpoint via network segmentation or firewall rules, allowing only trusted IP addresses to reach the administrative interface. Implementing web application firewalls (WAF) with custom rules to detect and block suspicious file upload attempts targeting the 'website_image' parameter can reduce risk. Additionally, disabling file uploads or limiting allowed file types and sizes at the application or server level can help mitigate exploitation. Regular monitoring of server logs for unusual upload activity and scanning uploaded files for malware is recommended. Organizations should also plan to apply vendor patches promptly once available and consider isolating the affected application from critical infrastructure to limit potential damage.
