0 CVE-2025-66802 is a critical Remote Code Execution (RCE) vulnerability affecting Sourcecodester Covid-19 Contact Tracing System 1.0. The flaw arises from improper handling of user-uploaded images, allowing attackers to upload a PHP reverse shell disguised as an image file. This enables unauthenticated attackers to execute arbitrary code remotely with full system privileges, compromising confidentiality, integrity, and availability. The vulnerability has a CVSS score of 9.8, indicating critical severity, and does not require user interaction or authentication. Although no known exploits are currently in the wild, the high impact and ease of exploitation make this a significant threat. European organizations using this contact tracing system are at risk of full system compromise, data breaches, and disruption of critical public health infrastructure. Immediate mitigation steps include disabling file uploads, implementing strict file validation, and applying patches once available. Countries with widespread use of Sourcecodester applications or strategic interest in Covid-19 tracing systems are most likely to be affected.
